Preserved Cold War Bunkers in Northern England

April 8, 2023 CarloRLeave a comment

The central role taken by Britain in WWII, firstly containing and then countering the expansion of the Third Reich, is duly and proudly celebrated all around the Country, with memorials and thematic exhibitions, often hosted in historical locations, regularly open for a visit.

The United Kingdom joined NATO as a founding member in 1949, and had already been at the forefront of a European anti-Soviet alliance with France since 1947. The strategic political and military ties with the US, pivotal in putting and end to WWII in Europe, were kept over the following decades, against the menace constituted by the Eastern Bloc. Thanks to its geographical position, and bolstering a nuclear arsenal, strategic bombers and submarines of its own, Britain was a major player of the Cold War.

Despite that, the Cold War left behind comparatively less memories than WWII, with only a handful installations open to the public, and somewhat out of the spotlight. In this regard, this reflects an attitude generally widespread in Europe towards the traces of the second half of the 20th century.

However, for people with an interest in the Cold War age, and more in general for those with a thing for (especially nuclear) warfare technology, there are two really unmissable sights in Northern England, which make for a vivid hands-on experience of the ‘era of Soviet threat’.

One is the Hack Green Secret Nuclear Bunker, with a fascinating history starting in WWII and spanning the entire duration of the Cold War. Here one of the finest collections of nuclear-war-related material in Europe can be found, together with much additional material from the era, in a largely preserved historical site.

Another is the York Cold War Bunker, built in the Cold War age to provide protection to the staff of the Royal Observation Corps (ROC) in case of a nuclear attack, as well as the ability to help coordinating fundamental public functions – health, transportation, food and energy supply, etc. – in a post-attack nuclear fallout scenario.

Both sites are regularly open for a visit, and provide a vivid testimony of civil and military plans and facilities seriously prepared in England for a nuclear apocalypse scenario.

Hack Green Secret Nuclear Bunker

The Hack Green site is located deep in the Cheshire countryside, about one hour driving south of Manchester. Actually, it is in a really secluded location, far from any sizable urban center, and away from major roads. Even today, when this facility is working as a top-level museum, some attention to the signs is needed to reach the site.

Once by the gate, you are immediately driven back in time by the appearance of the tall military-style external fence with official government signs, and by the blunt and in impenetrable appearance of the big concrete bunker – what you see is only the part above ground level! – with a big antenna protruding from the top. Nearby, you can see an apparently still off-limits area, with a now-dead radar antenna and an old Jet Provost trainer in RAF colors.

History

The history of the Hack Green site dates to as back as WWII, when it was established as one of the 12 most developed Ground Controlled Intercept (GCI) centers, out of 21 total nodes in Britain. Essentially based on the airspace scanning radar plants available at the time, the so-constituted ‘Chain Home’ surveillance system was operated by the RAF, and intended to track intruding German aircraft, thus directing air force planes against them. Radar aerials appeared on site at the time, suitable against relatively slow moving propeller-driven aircraft of those years.

With the start of the Cold War, and the need to reconfigure the defense against the USSR and Warsaw Pact forces operating with jet-powered aircraft of increasing speed, several modernization plans were started in Britain, aimed at implementing more effective detection and threat-countering radar technology, like ‘Green Garlic’, and later ROTOR. The latter called for the institution of a chain of detection nodes, not much dissimilar in concept from the older ‘Chain Home’ of WWII, but much more articulated, efficient and technologically advanced. At the time one of the most expensive government-funded operations ever, 66 installations were implemented all over Britain within ROTOR before the mid 1950s, with different roles in the network. The bunker you see today on the Hack Green site was one of them.

Keeping up with the fast-developing offensive technology of the 1950s and 1960s required a continuous update of the defensive network, in particular asking for the addition of intercontinental missiles to the enemy arsenal to counter. The US-led ‘Ballistic Missile Early Warning System’ (BMEWS) included 12 early-warning radar stations around the Atlantic, including a single station in the UK (RAF Fylingdales, Yorkshire, still in operation today). Before BMEWS went operational (early 1960s), triggering a re-organization of all other defense radar systems by the time obsolete, Hack Green took an interim role as one of only 4 radar stations operated by the RAF monitoring all military and civilian traffic through the British airspace, coping with new fast jetliners. The name of the Hack Green radar site in that stage was ‘Mersey Radar North’. Finally, in 1966 the RAF released the site to the government, which put it in mothballed status.

It was in 1976 that a new life began for Hack Green. Starting in 1958, the Home Office invested much in the preparation of an emergency structure, capable of keeping of managing a post-nuclear attack scenario, and keeping the basic public functions active. In the event of a total nuclear war, a failure of the national hierarchy and military chain of command was forecast, as a result of an extensive damage to the infrastructures and communication systems. In order to recover as fast as possible in such an emergency, the UK would split in 11 regions, each with a regional seat of government (RSG). In the region, a civil Regional Commissioner would take a leading administrative role, and would be responsible for coordinating disaster recovery operations, like supplying medical resources, food, water, and reconstructing infrastructures, while waiting for the national government to reactivate its functions. The Commissioner would be aided by the UK Warning and Monitoring Organization (UKWMO), which took over the function and organization of the older Royal Observation Corps (ROC) established during WWII. This structure was further potentiated in the 1960s and 1970s, also introducing a similar regional scheme for the military in case of a nuclear attack.

The seat of the RSG was in the Regional Government Head Quarters (RGHQ). Following some years when it was hosted in Preston, then in Southport, north of Liverpool, the RGHQ for the 10th region (then 10:2, following a split in two halves of this large region) found its home in Hack Green. The former radar facility was potentiated enormously, and set up with the ability to host 160 civil and military staff for 3 months without resupply in case of a nuclear attack on the UK.

Within the framework of the emergency plan for a nuclear attack, the RGHQs all over the UK went on operating until the demise of the USSR in December 1991, to be soon deactivated over the following years. Hack Green was scrapped of all content, and put up for sale in 1993. It was privately acquired in the mid-1990s, and carefully restored in some parts, or being stocked with interesting material from the Cold War era in some of the many rooms.

A tour of the bunker

Access to the bunker is via a concrete slide, and through a metal gate. Originally the male civil servants dorm, the first room you meet is now a kind of storage for items recently incorporated in the collection. These include a jeep, a model of an Avro Shackleton, and interestingly a nuclear warhead. The original system to activate the rooftop antenna is in a cabinet along a sidewall.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The ticket office and canteen are now in the original canteen area of the Hack Green site. Restored to a 1960s appearance, parts of the kitchen furniture are original from the site. Along the sidewalls are several memorabilia items, including some original Soviet emblems, not unusual today in museums on the other side of the Iron Curtain (see for instance here), but hard to find in the UK.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

An adjoining room reproduces the environment where the ROC would have worked in case of a drill or real nuclear attack. Among their function was the pinpointing of nuclear explosions. The forecast and monitoring of the fallout is strongly bound to the local weather and winds. This was kept under surveillance through reporting stations scattered on the UK territory (more than 1 thousand), which transmitted information to Hack Green and other RGHQ and UKWMO bunkers (see the York bunker later in this post). They could then coordinate recovery operations, avoiding extreme exposure to radiation of the emergency staff.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Monitoring was through dedicated sensors, and communication through specific transmission gear. Two display cases in the same room feature interesting instruments, training documents, and memorabilia items from the rich history of the ROC, documenting also their activities in WWII.

Ground floor

The Hack Green bunker largely retains its original arrangement. It is composed of a ground and an underground floor. Along the main corridors are interesting examples of the papers produced by the UKWMO, and by the civil defense service during the Cold War. Among them, are leaflets for the population, with best practices in case of a nuclear attack.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Also interesting are more technical posters from the era, either outlining the role of the public organizations monitoring a potential nuclear apocalypse scenario, or providing technical details on the effects of nuclear weapons – what to expect in terms of damage or health issues, depending on the type and local condition of a nuclear explosion.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

For sure a focal point in the exhibition of Hack Green today is the display of nuclear warheads, and nuclear-related material. Hosted in a room previously employed by emergency staff, the exhibition retraces with original material, mock-ups, rare pictures and videos, the history of the British nuclear arsenal, managed by the Atomic Weapons Establishment (AWE).

The WE177 was designed to constitute the backbone of the air-dropped nuclear deterrent of the UK. Examples of this bomb are on display together with technical material employed to monitor their status and manage launch or drills. In service between the 1960s and the 1990s in association with larger strategic bombers like the Vulcan, or smaller fighter-bombers like some versions of the Harrier or Jaguar, it could be assembled in some different versions, sharing the same baseline construction, but with nominal yields ranging between 10 to 450 kilotons.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Also on display are pictures and mock-ups of the old Polaris warhead, together with the original casing employed to transport this 200 kilotons item! A US design, the Polaris was acquired by the UK in 1963, to supply the Royal Navy and constitute the UK underwater deterrent. The Polaris missile featured a three-warheads fuse, bearing a total yield of 600 kilotons.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A very rare artifact is the warhead of project Chevaline, a British design to improve the potential of the Polaris, which saw limited service with the Royal Navy in the 1980s. The Polaris/Chevaline was replaced by the Trident missile system, still employed today in the nuclear deterrent role.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Besides the central exhibition of nuclear warheads, the display cases in the same room offer a wealth of super-interesting technical gear and memorabilia related to nuclear weapons. These include components and cabinets of radio and radar systems, to be transported on board aircraft or to be employed on the ground. These parts come from different ages, and from several Countries, including the Eastern Bloc – for instance, a very rare Soviet suit to work on high-power radar antennas for maintenance. Powerful radars actually emit rays with a high power-over-volume (power density) ratio especially in the vicinity of the emitting apparatus. This may even turn deadly for humans (roughly like being in a microwave oven would be!), and precautions are needed when working in such environment.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A really unique collection on display is related to Geiger counters and dosimeters. These include environmental and personal use devices, from various ages and nationality.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Two display cases are dedicated to material coming from beyond the Iron Curtain, most notably from the USSR and the GDR! It is really hard to imagine how this material could manage to come to Hack Green.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Part of the display is dedicated to the civil defense corps of different Countries, with helmets, emblems, papers and uniforms, showing how similar actions in preparations for a nuclear war were carried out in many Nations of continental Europe, also in the Eastern Bloc. Actually, a very close relative of the UKWMO RGHQ control center, with a totally similar function, can be found in a perfectly preserved condition in Poland (see this post).

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

More memorabilia items come from the history of civil defense in the UK. Among the most rare artifacts are the only surviving example of the ‘Queen’s telephone’, which was employed for enforcing the Emergency Power Act, which among other things may have transferred power to the Regional Commissioner. There used to be one such phone in each of the RGHQ, but all were destroyed for security reasons following the shut-off of the bunkers, except this one, and the one at the other end of the line – in the Royal residence.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

An adjoining room hosts a reconstruction of the radar screen room from the age Hack Green was employed as a radar station managed by the RAF. All panels are lit, providing a vivid, pure Cold War experience!

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

To the end of the main corridor, you can reach another entrance to the bunker, which is nowadays normally shut. However, this used to be the main entrance, and close to it are the control room of the bunker and the decontamination area.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The control room is not accessible, but the large windows allow to take a glance to its original appearance. It is still employed to control electric power and air conditioning. Manned nuclear-proof bunkers are customarily pressurized, sucking contaminated air from the outside, which is carefully filtered for poisons and radioactive particles, and pumping unfiltered bunker air to the outside (see this post for another example in a Soviet bunker).

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

People entering after work out in the fallout-polluted environment were decontaminated through showers, and used anti-radiation suits were left in an isolated sink still on display.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Before leaving the ground floor, you can find on the ground level the female dorm for the staff of the RGHQ bunker. In the same room, an original system for communicating on the very low frequency bandwidth has been put on display. This Cold War relic could be employed to issue orders to the strategic submarine force. This very cabinet was employed by Prime Minister Thatcher for ordering the attack against the Argentinian ship General Belgrano.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A final room on this floor is the sick bay, sized for the staff of Hack Green only, but equipped to manage health issues resulting from the exposition to a nuclear attack.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Underground floor

Descending to the underground floor is possible via the original stairs. The first room you meet features an exhibition of original Soviet uniforms, belonging to some high-ranking officials from various branches of the Red Army. Really hard to see in this part of the world, their origin is well documented.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Close by, is a small display of military material from the Soviet bloc, ranging from original weapons, to communication systems, emblems and instructional posters for the troops (similar to what you can find in dedicated museums in former Warsaw Pact Countries, like here or here).

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Nearby is a communication room originally employed by the military staff of the bunker, working in parallel with civil servants in the management of the nuclear emergency. Original radio transmission gear of military standard is still in place.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Before entering the core preserved area of the bunker, i.e. the rooms of the RGHQ, you can find the original water and air supply systems, and the corresponding technical cabinets, in a big room on the underground level.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The rooms of the RGHQ are all interconnected, and located to the side of the corridor on the underground floor. The way they look is from the days of activity of Hack Green as a RGHQ, i.e. the 1980s. Typical Cold War technology from the time is featured in this area.

Firstly, you enter the warning room, which used to be the contact point of the RGHQ with the national surveillance system. By design, the BMEWS at Fylingdales should have picked up an incoming ICBM within 30 seconds from launch, spreading an alert signal at all levels. This would have been received here and by the entire civil defense system within 90 seconds. This would leave roughly 4 minutes (out of a total of around 6 minutes for the missile to come to Britain from the Eastern Bloc) to tell the population of the incoming missile, which would happen through some thousands sirens scattered around the UK. The physical alarm signal management system was called HANDEL, and was employed from the 1960s to 1992. The apparatus on display at Hack Green, a node of HANDEL, is notably still working, albeit disconnected.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The warning room can be accessed directly from the Commissioner’s room, both an office and private room. Original maps and furniture can be found in this room, the only private one in the bunker. Immediately next to it is the cipher office, a communication office connecting – at least in non-emergency conditions – the center with the external world. Ciphered language was employed for safe communication with governmental offices, both domestic and abroad.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Next are a conference room, for meeting within the staff of the RGHQ, and a broadcast studio. The latter was focused on radio broadcast instead of TV, since the latter would not work in case of a nuclear attack. The idea was for the Commissioner to communicate directly with the administrative region, possibly repeating messages of national significance, or instructing about local disaster recovery actions, evacuation operations, etc.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The tour goes on with a very interesting area, stuffed with original electronic and communication material. Communication from the bunker to the other similar bunkers withing the UKWMO was possible through a dedicated system called Emergency Communication Network (ECN). The main function was that of constantly updating the map of the fallout and of the operations taking place at all levels, including all surviving infrastructures. Many maps and teletypewriters, original components of the system, are part of the display.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The ‘brain’ of the system was the Message Switch Exchange (MSX). A top-tier system elaborated by British Telecom in the 1980s, it looks exceptionally complex. The lit cabinets and modules provide a really vivid impression of how it should have looked like back in the Cold War years. The electronic cabinets and wiring driving to the rooftop antenna are still lit as well.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A rare, incredible portable satellite communication antenna is on display. This was employed in peacetime condition, and stored inside the bunker when under attack.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

The screens where the meteorologists and nuclear scientists displayed all the information gathered and prepared forecasts are another unusual Cold War sight.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Perhaps unexpectedly in a 1980s hi-tech environment, a purely analog, wired telephone exchange system is on display. This is original as well, and was kept in service as a ‘last line’ backup system within the ECN until 1992, should the futuristic MSX system fail under an attack.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A complement to the exhibition of the RGHQ is the fire control room, where a big screen and several communication consoles were employed for directing firefighting actions at a regional level. Following the experience of Nagasaki and the extensive nuclear tests of the 1950s, it is known that fires resulting from the extreme temperature and radiation intensity associated with a nuclear explosion are possibly even more dangerous to buildings and infrastructures than the shock-wave itself.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A display which is not original from Hack Green, but found an ideal home in this bunker, is made of a reconstructed room from the Regional Air Operation Center (UKRAOC), which would gather information from the BMEWS. The material on display used to be at RAF High Wycombe, where the UKRAOC facility was located in the Cold War years.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Fed by the BMEWS early warning station at Fylingdales, the apparatus in this room was constantly updated on the defense situation. A Soviet ICBM attack would be detected here, and from here the alarm signal to the entire national civil and military defense system would be triggered. This really one-of-a-kind reconstruction is really evoking, with the original panels all lit, and a dim light background!

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

A final room on the underground floor hosts a reconstruction of a Soviet missile launch room. Perhaps not accurate as a reconstruction, it is however centered on original material and memorabilia items from the Soviet bloc. This area has been employed as a set for movies.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

At the base of a second stair well ascending to the ground floor you can find a reconstruction of one of the more than 1 thousand peripheral posts of the ROC. Such posts, scattered on the UK territory, gathered information for the RGHQ, and constituted the ‘sensors’ of the nuclear attack detection network. The technical gear includes over-pressure and radiation intensity transducers.

Getting there and visiting

The bunker is in a very secluded location, about 25 miles west of Stoke-on-Trent, and roughly 60 miles from Liverpool and Manchester. Very little advertised in the area, and not much known to the general public even in the UK, this hidden gem can be reached very conveniently by car, not much conveniently with public transport. The exact address is French Ln, Nantwich CW5 8BL, United Kingdom.

The bunker was built far from the crowds. Do not be worried as you see the road getting narrower and you feel like your NAV is taking you to nowhere – you are probably on the right path! Once there, you will find a large inside parking, and a top-level management of the entire facility.

Hack Green – Secret Nuclear Bunker – Crisis Regional Government – Cold War – UK

Visiting is on a self-guided basis, with tons of explanatory panels and illustrations allowing to make the most out of your visit even if you have just a normal interest and preliminary knowledge of the topic. For a specialist, this super-interesting, one-of-a-kind site may require at least 2 hours for capturing the details, and possibly take pictures. Website with visiting information here.

York Cold War Bunker

Besides the impressive Minster and the beautiful historic town, York has the distinction of being the seat of one of the few Cold War bunkers preserved in the UK. Differently from Hack Green (see above), the bunker in York was installed relatively late in 1961, in the middle of the Cold War. Since then and until the collapse of the USSR, it acted as a node in the UK Warning and Monitoring Organization (UKWMO), collecting information and coordinating emergency actions around York in the event of a nuclear attack. A cluster of reporting points was linked to the bunker in York, which took the name of Headquarters of the N.20 Group within the UKWMO.

An eminently intelligence collection and information relay facility, the bunker was manned by the Royal Observation Corps (ROC), who provided voluntary civilian staff to support the monitoring and communication functions of the bunker in the UKWMO network. The bunker ceased operations and was basically sealed in 1991. Until that time, the ROC ran the facility, carrying out regularly scheduled drills and simulations. The bunker was designed and sized to offer its staff a self-support ability of a few weeks in a nuclear fallout scenario. Besides all supporting facilities, including water tanks, pumps and power generators, the facility was centered on a set of sensors for nuclear blast detection, as well as provision for fallout forecast and monitoring.

The bunker has been taken over by the English Heritage, a structured nationwide historical conservation association, which restored the site and opened it to the public.

The York Cold War Bunker is not far from the historical center, yet in a quiet residential area. Access is from a small parking area among low-rise buildings. The greenish paint of the concrete walls and the tall metal antenna on top cannot be spotted from much farther away than the parking itself. Curiously, the pedestrian door of the bunker stands some feet above the ground, and can be reached via a concrete stairway. Then once on top and inside, you need to descend some flights of stairs to get underground.

York Cold War Bunker – York – England

Compared to the Hack Green bunker, the York group headquarter is more cramped, with smaller rooms, lower ceilings and narrower corridors.

York Cold War Bunker – York – England

The first part of the visit covers the supporting facilities. These include a ventilation system, which as customary for nuclear-proof bunkers (but the same is true for older bunkers dating from WWII) filtered the incoming air and ejected the inside air, basically pressurizing the bunker environment with respect to the outside atmospheric pressure. This avoided passive ingestion of contaminated air from the outside.

York Cold War Bunker – York – England

A power generator and a water pumping system are also visible. A control panel for all the plants has been preserved, similar to the machinery in this area, dating from the time of construction.

York Cold War Bunker – York – England

The centerpiece of the visit is of course the reporting room. The reason for putting a headquarters in relatively low-sized York was the presence in the area of significant food production industries, as well as of a major railway node in Northern England. Furthermore, military facilities like the only BMEWS station in the UK happened to be in Fylingdales, northern Yorkshire. These features would make York a valuable strategic target for an attacking enemy. The main function of the bunker within the UKWMO was that of ascertaining the position and intensity of a nuclear explosion on the territory covered by its jurisdiction.

Anticipated by the early warning ballistic missile detection system protecting the UK, the hit could be recorded by the sensors available in the bunker or in other reporting points scattered around in the country. The bunker would then try to predict and follow the evolution of the fallout. This would allow coordinating emergency and recovery actions including fire suppression, medical evacuation, water and food transport and supply, etc.

The central reporting room looks mostly like an operations room in a military headquarter. It is structured on two levels, with large maps and boards for visually updating the situation and writing information. Batteries of telephones and teletypewriters allowed obtaining communications and sending updated information to allow emergency services as well as decision centers to carry out post-attack operations. This system was not dissimilar from the counterpart beyond the Iron Curtain (see for instance this center in Poland).

York Cold War Bunker – York – England

Nearby the reporting room, the components of the sensor suite allowing to detect the position and intensity of a nuclear explosion are on display.

The first is the bomb-power indicator (BPI). The working principle is that of reading the over-pressure caused by the shock-wave invariably produced by an explosion, and particularly intense for a nuclear explosion, releasing an immense amount of energy in a small volume and within a very short time. The supersonic traveling shock-wave is responsible for the mechanical breaking of building and superstructures, like antennas, suspended power lines, bridges, piers, etc. Being a wave of pressure, its intensity can be measured by pressure transducers, which for the BPI show the reading on a simple analog dial.

York Cold War Bunker – York – England

The transducer, seen handing from the ceiling in the exhibition, would stand on the rooftop of the bunker, exposed to the explosion. This type of sensor was also installed in smaller reporting points scattered over the territory of the UK.

A second sensor was the ground zero indicator (GZI). Here the working principle was also very simple. The main element in the GZI is a metal drum with a small hole in the side, and a piece of photographic paper covering the inside surface of the cylinder. An explosion would send a high-energy light beam through the hole, producing an impression on a precise point on the paper. By positioning in a very accurate way the drum on its pedestal on top of the bunker, according to a precise fine-tuning, it was possible to retrieve the direction of the incoming beam. By composing the reading of more than one precisely-located drum, it was possible to pinpoint the position of the explosion by triangulation, both in terms of geographical position and altitude. The latter is a very relevant practical information, since for instance the quality and hazard of the fallout are strongly related to the proximity of the explosion to the ground.

York Cold War Bunker – York – England

The GZI, a purely analog sensor, had the odd feature of requiring collection of the photographic paper by venturing outside of the bunker after and explosion, i.e. facing the fallout.

The third and most evolved system on display is an AWDREY computer. The name stands for Atomic Weapon Detection Recognition and Estimation of Yield. This artifact is very rare to see, and a quite refined piece of engineering for the time. It was supplied to 12 headquarter bunkers of the UKWMO, including York, and was operative from the early 1970s. The computer is the computational part of the system, whereas the detection system was based on a sophisticated transducer put outside, on top of the bunker. The working principle was much more sophisticated here, and related to the evolution of the intensity of the radiation coming from the core of the explosions in the first instants of the detonation process. Several stages of a nuclear explosions happen in a row on a scale of a few millionths of a second. These include a predictable oscillation of the intensity of radiation. The exact features of this oscillation are correlated to the yield of the explosion. The ability of AWDREY to collect and interpret data from the early stage of the explosion would allow it to reconstruct the position and yield of the explosion at once.

York Cold War Bunker – York – England

Tuned on experimental data from nuclear testing in the field, this system delivered good general performance, with some inaccuracy in case of intense atmospheric phenomena taking place – or during fireworks, when the York system was apparently misled in one occasion, interpreting it as a Soviet attack!

York Cold War Bunker – York – England

The tour is completed with a view of the dorm for the civil servants of the ROC, and with a short exhibition on some historical and political aspects of the Cold War.

Getting there and visiting

The York Cold War Bunker is professionally managed by the English Heritage. Visiting is only possible with a guide. Please note that as of 2022, pre-booking is strictly necessary, since there is no ticket office on site. The guided tour lasts about 45 minutes, including a well-crafted introductory video. At the time of writing, only the first underground floor is open for a visit, but plans for an expansion of the visible part of the facility are being drafted.

The tour is very interesting and detailed, with some educated humor to make it more enjoyable! For specialists, it will be too quick, especially if you like to take pictures. However, the site indeed deserves a careful look also for the more technically-minded people, especially considering the little number of similar facilities open in Europe – and of course in the UK, where it is a one-of-a-kind destination, and a true must for Cold War historians.

The location is about two miles west of York Minster. Convenient to reach by car, several public parking lots are available in front of the gate or in the neighborhood. The exact address is Monument Cl, Holgate, York YO24 4HT, United Kingdom. Website with full information here.

Soviet and East German Relics North of Berlin

September 29, 2019June 28, 2023 CarloRLeave a comment

For the full span of the Cold War, the communist German Democratic Republic has been a highly militarized region.

Due to its position right on the European border between NATO countries and the USSR-led eastern bloc, this relatively small state was kept in high consideration by the Soviet military staff in Moscow. In the re-organization of Soviet forces following the end of the Great Patriotic War (i.e. WWII), of the four Soviet groups of forces stationed in all satellite countries outside the Soviet border, one was specifically named ‘Group of Soviet Forces in Germany’. This group was headquartered in Wünsdorf, the former location of the German OKW south of Berlin (see this post), and had under its command a force of some hundred thousands troops, divided in two tank armies, an entire air army, three mixed armies and a supplementary artillery division. Supplies were in no shortage either, with some tens of fully operational airbases/tank polygons, academies and housing for all the troops and respective families.

Despite the very significant Soviet presence, the GDR invested a huge capital of its own in the development of a full-scale military strength. The East-German National People’s Army (NVA) received top-tier technology from the USSR, and did of course manufacture military supply of all sorts. Sustaining this army, together with the enormous para-military organization of the internal Ministry of Security – the ill-famed STASI – and other governmental organizations, military expenses undoubtedly contributed to the economical crisis hitting the GDR in the 1980s, setting the scene for its final demise.

The region north of Berlin was particularly rich in military and governmental installations, some of them highly classified, their history shrouded into mystery. You can find some information in dedicated posts on this website (see this post, also here and here).

In this chapter, some more items of interest are featured. Four of them are abandoned tokens from Soviet occupation. A nice belle-epoque villa on the shore of the Röblingsee in Fürstenberg, where the headquarters of the 2nd Guard Tank Army was headquartered since Stalin’s era to the withdrawal of Soviet forces in the 1990s, is the first of them. The second is a unique, forgotten Soviet monument, to be found less than two miles south of Fürstenberg. Two more are memorials and cemeteries, for Soviet troops who perished in the last stage of the Great Patriotic War (WWII) around Berlin.

Other three points of interest are instead GDR-related. The first is the former academy for future leaders of the communist party, established in Wandlitz in the years of Stalin, and initially led by Erich Honecker, later to become the omnipotent leader of the GDR for two decades. In the same area north of Berlin – and precisely in Waldsiedlung, today a nice clinical campus in the countryside – are the former private houses of the members of the central committee of the communist party of the DDR – personalities like Walter Ulbricht, Erich Honecker, Erich Mielke and Egon Krenz lived here with their families. Finally, you will find a glimpse from the so-called ‘Honecker bunker’ in Prenden. This big and highly classified installation was prepared in case of war, to protect the leadership of the GDR and ensure safe communication with Moscow.

Photographs were taken in summer 2019 and 2021.

Soviet 2nd Guard Tank Army Headquarters, Fürstenberg/Havel

Among the Soviet forces permanently stationed in the GDR in case of war, there used to be two entire tank armies, the 1st and 2nd. The former was headquartered in Dresden, whereas the 2nd – named ‘Red Banner’ – in Fürstenberg/Havel.

The headquarter in Fürstenberg is basically an old villa, possibly dating to the late 19th century or a slightly more recent time. The villa is somewhat unusual in the panorama of todays Fürstenberg. This is a nice and lively touristic town, where many Berliners come to find a retreat in nature, less than 1 hour driving from home. Thanks to tourism-related activities, the area has got rid of the Soviet/East German grayness, and is now a typical village in the German countryside, graced with a creek and a small lake, where canoes and small boats are always roaming around.

In stark contrast with this, the villa is today completely abandoned, with overgrown vegetation almost hiding it from the main road. Access to the premises is easier from the back, where you first meet a typical Soviet prefabricated wall, and service buildings with evidence of a communist design – the usual yellow paint and railings on the windows with the stylized ‘radiant dawn of communist revolution’.

Getting closer to the house, you meet an access door, possibly going to a bunkerized area underneath. The house is in a really bad shape, with rotting walls, plants growing on the balconies and roof. The inside has been made completely inaccessible. A typical East German light is still hanging from the back wall.

To the front, a temple-like decoration contours the main door. It is difficult to say whether this decoration was there since the beginning, since it appears rather different in style from the rest of the villa.

A highlight of this site is the statue of Lenin still standing ahead of the front facade. The statue is in a relatively good shape. It looks like the man was portrayed during a discussion.

The concrete sculpture was accurately made, as witnessed by the facial expression and details in the embroidery of the tie.

On the front side, the villa used to be reachable with a large flight of steps climbing uphill, with Lenin on top. Today this perspective is gone, for vegetation has totally invaded the steps, and the front of the house is not visible from the street.

Getting there and moving around

The villa is located in central Fürstenberg on Steinförder Strasse (possibly) 44, on the southern side of the road. The house and its large garden estate are abandoned, but all other houses around are not. Getting closer without being spotted is easier from the backstreet. Technically speaking, the latter is accessible for residents only, so you may park somewhere else and come closer by foot. Visiting may take about 30 minutes with time for the pictures, for the house is not accessible inside.

It should be remarked that this site is probably not public, and at an unpredictable time it may be either restored or demolished – so checking it out may be not possible for long.

Soviet Monument, Fürstenberg/Havel

A rare example of Soviet commemoration monument can be found very close to Fürstenberg. Apart from the monumental sites in Berlin (see here), a number of smaller Soviet monuments are to be found around the GDR – impressive ghosts of a bygone era.

Among the best preserved are that in the former tank base of Zeithain (see this post), and this one in Fürstenberg.

The monument is composed of two parts, basically two concrete curtains facing each other on the sides of a small apron.

The smaller panel to the south is the most intriguing. It is apparently a celebration of an economic plan of the Soviet Union. It is all about the growth in production in several areas of industry and farming, likely resulting from careful planning by the top of the Soviet government.

Between a citation from Lenin and a stylized image of the Kremlin, several panels cite one by one the increases in production of anything from oil to weapons, from milk to corn.

To the back of the monument, the only remaining feature is a remarkable head of Lenin, with yet another citation. It is likely that other features have been removed by vandals, as empty frames can be seen aligned along this face of the monument.

The larger panel to the north is a celebration of the march to Berlin during the Great Patriotic War, likely related to specific actions of the Guard Tank Armies. The central slab features an image of the Soviet monument in Treptower Park, Berlin – one the most famous commemorative monuments in the Soviet Union, as witnessed by numerous images to be found still today in many museums in the former USSR (see for instance here).

Close by, reproductions of decorations and captions of what happened on some days of 1944 and 1945 are reported.

On the left panel you can see a reproduction of the march to Berlin, from the battlegrounds in the USSR, through central Europe and Germany. It is likely that some metal parts of the monument once used to connect the ‘points of interest’, but these have disappeared due to vandalism.

On the right wing of the monument the names of Heroes of the Soviet Union possibly from the Guard Tank Armies are cited one by one. Close by, the image of the ‘Soviet Motherland Calling’, pretty usual in Soviet war iconography, can be found together with other typical emblems.

Getting there and moving around

This monument is not maintained nor protected. It is open air, unfenced and freely accessible. It will be hopefully restored or moved to a museum, as the weather and vandals are taking their tolls. It can be reached along the road 96 about 1 mile south of Fürstenberg, immediately to the west of the road. A small unofficial parking area can be found ahead of it, making a quick visit really easy.

Soviet Memorial and Cemetery, Rathenow

The Soviet memorial in Rathenow is one of a number of smaller military cemeteries for Soviet troops in the region around Berlin. Soviet soldiers perished in the area in the thousands in the final stage of WWII (1945), when the Red Army entered the northeastern part of todays Germany from Poland, pushing towards Berlin and fighting against the agonizing but still fierce German Wehrmacht.

Apart from the gigantic and formal monuments in Berlin (see this chapter), more modest shrines are scattered around the German capital city, all built roughly in the same period, between the end of the war in Europe and 1950, in the years of Stalin.

The Rathenow site is a small town cemetery, a proportionate, down-scaled version of its larger counterparts in Berlin – especially Schönholzer Heide (see here) – and can be found in the center of the sleepy town of Rathenow. A central obelisk with a commemoration plaque is topped by a golden five-pointed star, the symbol of the Red Army.

Soviet Red Army Memorial Rathenow

A number of soberly designed grave stones for as many Soviet troops are aligned in rows, creating an elegant perspective. Most of the graves bear complete names, as well as the birth and death years. Similar to the war cemeteries dating also from WWI (see for instance here and here), the very young age of most of the troops in the final struggle around Berlin is readily apparent.

Soviet Red Army Memorial Rathenow

Despite being fenced and of course not left in a state of disrepair, the green areas immediately outside of the perimeter of the monument in Rathenow are somewhat neglected, perhaps reflecting a fading interest for this monument.

Getting there and moving around

The Soviet monument in Rathenow can be reached at the crossing of Ferdinand Lassalle Str. with Friedrich Ebert Ring, in central Rathenow. The monument is very compact and can be toured in a few minutes.

Soviet Memorial and Cemetery, Blumberg

The monument in Blumberg, in the northern outskirts of Berlin and really close to town, is smaller than the one in Rathenow (see above), but shares the general arrangement with it.

A central pillar with a commemoration slab is surmounted in this case by a statue of a Soviet soldier, holding a Red Banner flag.

Soviet Red Army Memorial Blumberg

Ahead and around the pillar, gravestones put flat on the ground are aligned in a perspective. However, the overgrown vegetation is basically hiding these lines of tombs, so that even from a small distance the central monument appears as an isolated item, put in the middle of a grassy area.

Soviet Red Army Memorial Blumberg

Actually, the major difference with other monuments of the kind lies in the rather remoteness of the one in Blumberg. It is a listed historical landmark, and therefore at least minimally cared for, but on the other hand, it is located relatively far from todays nearest settlement, hidden in the trees, and out of sight for anybody except people going there specifically for it. This makes it rather mysterious, a silent memento of old memories.

Getting there and moving around

The monument is conveniently located just out of the A10 highway (the external ring of Berlin), in the settlement of Ahrensfelde. You may reach Chausseedreieck and drive to its western dead end, where you can conveniently park. From there a grassy path points south into the trees, and in less than 150 yards you will find the monument. The size of the monument is small, hence no further walking is needed. A mosquito repellent is highly recommended in the warm season.

Free German Youth Academy & Joseph Goebbels Manor, Wandlitz

Deep in the countryside about 25 miles north of Berlin, about 3 miles from the small touristic village of Wandlitz, you can find a couple of highlights from the troublesome past of Germany, sitting side by side, close to the small Bogensee lake.

The first is the country estate of Joseph Goebbels, the famous minister for education and propaganda in the years of the Nazi dictatorship. This villa has been built in the war years, and often used by its owner, also for receiving guests. Goebbels obtained the estate as a birthday present from the Nazi Party.

Incredibly, the manor, built in a typical German country style, was not demolished after the war – so unlike other residences belonging to Hitler or his fellows, it is still there to see. It survived denazification, Soviet occupation and 40 years in the GDR as part of a school (see below).

The outside is the only part you can see. The appearance is sober, with simple lines and not much vertical elevation – it nicely integrates in the natural setting.

Joseph Goebbels Manor Nazi Leader Bogensee Wandlitz Hitler Present

Access to the courtyard is from a small road, now part of the inner network of the larger complex surrounding the manor.

This complex is actually the other peculiar item you can find in Wandlitz. This enormous academy was built in 1951, on behalf of the Free German Youth (FDJ), a youth-training organization founded and originally run by Erich Honecker, later to become the general secretary of the communist party of the GDR in the 1970s and 1980s.

The academy was designed by Hermann Henselmann the same architect who designed Karl-Marx-Allee in the Soviet sector of Berlin – one of the most iconic ‘Stalin’s-style’ perspectives in the world. The complex is composed of two large opposing buildings, on the short sides of an internal courtyard. These hosted common areas, lecture rooms and a theater.

Along the longer sides of the courtyard are buildings with bedrooms and services for around 500 students.

German Communist School Academy Bogensee Wandlitz FDJ Jugendhochschule Jugendleiterschule DDR Honecker Henselmann

The academy was for the future staff of the communist party, and in later years of the Cold War it was attended also by international students from communism-leaning nations, or sometimes even from NATO countries.

German Communist School Academy Bogensee Wandlitz FDJ Jugendhochschule Jugendleiterschule DDR Honecker Henselmann

Following the collapse of the GDR, the building went on hosting educational institutions until the early 2000s, owned by the regional government. It was then mostly shut off, with some ancillary buildings still hosting institutions connected with the administration of the natural preserve around. It was put up for sale, for a while, but all potential customers failed to present satisfactory conversion plans. An expensive and inconvenient ghost from a forgotten era, as of 2019 its fate has not been sealed yet.

Today the place is not completely abandoned. Basic preservation works are being carried out, thus avoiding the roof to collapse or the walls to rotten. The names of the blocks are likely not from the GDR years. Similarly, a board with notices and maps dating from later than 1989 can still be seen, a witness of the post-GDR activity.

The garden is not growing totally wild, and some architectural addition must have been tried in a recent past – like a small modern fountain ahead of the common building to the southwest of the complex. The buildings are still supplied with electrical power – there are lit lights above some doors – and it is discretely guarded to avoid vandalism.

Getting there and moving around

Accessing the area is possible following the L29 from Wandlitz. About 1 mile from the village, the road changes its name to Wandlitzer Strasse. There is a local road with limited access taking to the east. You may park there, and proceed along the road by foot for about .5 miles to reach the heart of the complex. This is surrounded by private houses. There is no fence, but there are proximity sensors which trigger an inspection. I was reached by a warden on a car soon after my arrival. He spotted me, but did not come close, likely noticing I was just taking pictures outside.

The site is rather mysterious and well worth a quick visit for interested subjects. Touring the site will not take more than 45 minutes, taking all the pictures.

Private Homes of the Members of the Central Committee of the Communist Party of the GDR, Waldsiedlung

Similar to other top-ranking figures in the Soviet chain of command – like Stalin and others in his communist entourage, who did not spend much of their time in public or close to crowded places in central Moscow – the masters of the communist party in the GDR had their homes in the trees north of Berlin, relatively far from the city center and from the governmental buildings.

Actually, many of them lived together in a rather compact residential district, called Waldsiedlung. Access to the area was obviously controlled, but once inside the place was somewhat similar to a holiday settlement, with smaller single or two-family houses located along quiet alleys in a rural setting. The architecture is far from lavish – all houses are very similar to one another, and are designed in a plain typically East-German style from the post-WWII era.

Today, the settlement in Waldsiedlung has been converted into a campus for clinical studies. However, the original architecture of the place has been left mostly untouched, and explanatory panels telling quick information about the history of the residence have been planted ahead of most of the housing once occupied by old communist big brasses.

The office by the gate, and the metal gate itself, are totally original, as can be seen from historical pictures.

Waldsiedlung – GDR Communist Party private homes

Among the first buildings past the gate is a former congress center/clubhouse/gathering facility for the inhabitants of the residence.

Waldsiedlung – GDR Communist Party private homes

Moving on to the northern part of the settlement, the modest house of Erich Honecker and his wife Margot can be easily found. The two-storey construction has a patio on the backyard. A mystery wooden hut can be found next to the latter.

Waldsiedlung – Erich Honecker’s Home

The Honeckers were forced to leave this house in the turmoil following the collapse of the wall and the starting of the reunification process. Honecker fled to the Soviet Union in seek for protection, quickly departing from the Soviet base in Sperenberg (see here). He was trialed in absentia, in connection to the order issued to the GDR border guards to used deadly force against people trying to pass the ‘anti-fascist wall’, and the ensuing deaths. He remained in the USSR until also that dictatorship collapsed, and he was forced to escape to South America, where he died soon after.

To the far end of the same alley is the house of Walter Ulbricht and his wife Lotte. Somewhat larger than Honecker’s house, it is however not much more evolved in adornments or architectural fantasy.

Waldsiedlung – Walter Ulbricht’s Home

On another alley, parallel to the previous one, is also the house of Erich Mielke, the uncontested head of the ill-famed STASI, since its early years to the end.

Waldsiedlung – Erich Mielke’s Home

The man was captured and trialed for an old case of homicide, after the shut-off of the STASI monstrous machine. He died soon after.

Today even these smaller buildings have been converted for a new function in the clinical campus. Therefore, they cannot be toured inside. However, strolling in this inconspicuous, quiet village where a huge concentration of power used to be seated, provides a strange feeling.

Getting there and moving around

The Brandenburg Clinic, which has now taken over the Waldsiedlung residence for the members of the GDR government, is on the road N.273, between Bernau and Wandlitz. The clinic in Waldsiedlung is rather busy, and the parking ahead of it may be crowded. However, since the place is guarded and access regulated, that is the only credible parking option also for a historically-themed visit. You can access the area by foot undisturbed, and take photographs of the exteriors. There are explanatory panels ahead of many of the former residential homes.

Honecker Bunker, Prenden

Geographically very close to the academy in Wandlitz (see above) – less than 1 straight mile away – the bunker in Prenden is the central piece of a network of bunkers and military hardware, designed an built on behalf of the National Defense Council (NVR) of the GDR from 1973 onward, and named ‘komplex 5000’. The purpose was protection of the leadership of the GDR in case of a crisis or attack from the West.

The bunker is Prenden, technically listed as ’17/5001′, was a control center of incredible sophistication, designed to withstand nuclear blasts, and with direct communication with other sub-nodes of a larger communication network, thus granting safe communication and broadcasting ability, allowing to lead the country in case of a crisis. The bunker was intended to host the general secretary of the communist party, i.e. Erich Honecker, when the bunker was commissioned in 1983 – hence the unofficial name ‘Honecker bunker’.

The premises of Prenden are now largely in private hands, but some parts are apparently publicly accessible – the original fence has been completely torn down. The bunker itself is sealed, and can be accessed only on a few days per year with a guide.

The official entrance to the area is through the original GDR-made gate. This is closed however, for it is now the entrance to a small private industrial complex.

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

Traces of the original fence, as well as piping and vents for underground rooms, can be found around the hill on top of which the installation is standing.

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

Some service buildings in typical communist style can be still found, despite demolition works having taken place. Proximity sensors and signs delimit the private property area.

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

The three-storey building on the southwestern corner of the complex used to be the ‘front office’ of the bunker. Today, it is in a really bad shape.

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

Inside, traces of the original furniture and services can still be found, albeit much deteriorated.

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

Access to the bunker is on the underground floor. You may notice the prison-like railings ahead of the access stairs. A feature that might make you jump when you are exploring alone – if walking in a forgotten communist government building, deep in the silent German countryside, was not enough… – is the lit bulb hanging over the entrance to the bunker – really unexpected!

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

Besides the building, a shelter-garage for trucks and cars is still in a relatively good shape.

Honecker Bunker Objekt 17/5001 Prenden DDR Berlin

Getting there and moving around

The Prenden bunker is not publicized, but it can be neared easily with a car, about 1 mile south of the small village of Prenden, along Utzdorfer Strasse. The gate can be clearly spotted, but it will be likely closed, and there are obvious ‘no trespassing’ signs and labels of private companies. You may park outside and proceed along the side of the property to the back of it, where the abandoned building mentioned above can be found. Whether this is still on private land or not is not very clear. There are proximity sensors between the abandoned building and the rest of the complex, likely to trigger inspection if you get too close to the (surely) private part of the complex.

Venturing in the building is definitely not safe, and the bunker entrance is usually closed. Official visits to the bunker are possible on guided tours arranged irregularly about once per month (please browse the internet for more info on visiting, cause I could not find an official site of the place to link here).

Cold War Forts and Museums in Denmark

September 15, 2019May 9, 2020 CarloRLeave a comment

During the Cold War the condition of Denmark on the international stage was among the most complex. Coming from years of neutrality before WWII, conquered in a matter of days in spring 1940 by neighbor Germany, at that time in the throes of the Nazi fury, it found itself on the front line of the two opposing blocs soon after May 1945.

Having not been occupied by the Soviets during WWII, it could better choose about its future, and in 1949 the mother country of the Vikings joined NATO as a funding member – unlike neighbor Sweden and Finland – thus giving its availability to its Allies to help countering Soviet influence over the territory under its control.

History in brief

Often overlooked when looking at the world map for its relatively small area, at the beginning of the Cold War the geographical position of Denmark nonetheless was – and, to some extent, still is – strategically very relevant. It is right on the inlet of the Baltic Sea, with a proximity to the foreign coasts of Norway and Sweden such to allow easily blocking the marine traffic on the Kattegat strait, when needed, by means of mere cannon fire from the coast. During the Cold War, this meant a virtual control over a sea where the USSR and Eastern Bloc Countries had many industrially relevant and non-freezing ports, as well as navy bases. Furthermore, the islands of Denmark, where large cities like Odense and Copenhagen are, can be found as close as 1.5 hours by boat to the coast of the German Democratic Republic – once one of the most heavily militarized countries on earth, also thanks to a massive Soviet presence. The smaller island of Bornholm, further east, is even closer than that to the coast of Poland.

A curious fact in history demonstrated the proximity of Denmark to the communist sphere of influence, shaking the minds of top ranking Soviet military. On March 5th, 1953, on the very same day of Stalin’s death, the first defection of a jet fighter from the Eastern Bloc took place, when a Polish MiG-15 on a routine flight along the Baltic Coast suddenly left his mates and rushed to Bornholm, where it landed on a field, leaving the aircraft in almost pristine conditions.

The cautious reaction of the Danish government and military forces reflects the position of the country at the time – they had identified the USSR and their satellites as a clear and present threat, and consequently they had taken the side of the West. Yet Denmark knew it could not withstand a direct military hit by the Soviets for more than a few hours, therefore as a form of self-protection, any form of provocation, at least in the early 1950s, was carefully avoided. While the pilot of the MiG was allowed to escape to the UK and then the US, the aircraft was quietly ceded to the US military for technical inspection in the FRG, but then re-mounted and returned to Poland. Other examples of a policy of constant detente with the Soviet Union are represented by the refusal to have NATO bases on its territory, or despite the adoption of the Nike missile system for the airspace protection, the missed deployment of the corresponding tactical nuclear warheads.

Of course, in recognition of the strategic relevance of this pleasant country, plans for a Soviet invasion which would strike in northern Europe, with the objective of reaching to the ports of the North Sea in less than a week from Eastern Germany, included as a major target the quick occupation of the Jutland peninsula, and of the islands of Denmark as well. This had to be done by marching fast through the northern regions of the Federal Republic of Germany, and simultaneously landing troops on the Danish islands.

About this post

Albeit not enough populated to sustain an army capable of resisting the eastern opponents on the other side of the Iron Curtain, thanks to its position on the map, Denmark took over seriously a fundamental border monitoring and interdiction task in favor of all NATO forces. Two tangible witnesses of this are the military bases of Stevnsfort and Langelandsfort, both located on the southern coasts of the islands, overlooking key sea straits, and pointing south to the East German coast. Both have been shut down after the end of the Cold War, and now they can be visited as top-tier military museums.

Further souvenirs from the Cold War era can be found in the Defense and Garrison Museum in Aalborg, a wide-spectrum military museum with a focus on WWII and the Cold War, and in the Danish Museum of Flight, where exemplars from the heterogeneous wings of the Danish Air Force are displayed, together with unique specimens of Danish aircraft production from the inter-war and early Cold War period.

This post covers all these four sites, visited in summer 2019. Presentation doesn’t follow any special order.

Cold War Museum Stevnsfort

This museum on the eastern coast of the island of Zealand (the same of Copenhagen) is actually a former Cold War military fort, operative from the early 1950s to the year 2000. It was re-opened as a museum in 2008, carefully preserved in most part in the forms it had in the 1980s, the most technologically advanced years of the Cold War.

By the entrance to the museum area you can see three surface-to-air missile, namely an old Nike-Ajax, and a much more performing – and bigger – Nike-Hercules. Both were part of the US Nike airspace protection system, which was deployed in Denmark around Copenhagen. The missiles are from the Cold War years, but were not originally present on Stevnsfort.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Strictly speaking, Stevnsfort is not the part of the installation you access first. The area you meet when getting in from the parking used to be a missile base in charge of the Danish Air Force. It was built for the Hawk system, another US interdiction surface-to-air missile system, the heir of the Nike system. Actually, Nike Hercules batteries in Denmark were withdrawn from use – as elsewhere, see this post – in the 1980s. Their role was taken over by Hawk missile batteries, gradually entering service since the 1960s, and operated till 2005 in Denmark.

Differently from its predecessor, the radar-based Hawk system was entirely movable, making it more flexible and less vulnerable. As a result, there are basically no bunkers in this area, and all constructions here are ‘soft’. Target designation and tracking was demanded to three sub-systems, namely a radar-pulse antenna for target individuation, an interrogation friend-or-foe (IFF) and a target-tracking/homing antenna.

Two radar-pulse antennas are displayed. The aerial emerges from a tent, which covers the electronics and motor of the system. Both are mounted on a truck trailer, which is actually totally movable. The range of the radar scanner was about 75 miles.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

The IFF antenna is a smaller barrel-shaped device coupled with systems on-board aircraft, needed to distinguish between an enemy aircraft and a friend or ally. The target-tracking/homing antenna, with its distinctive two radar dishes, shares the installation setup with radar-pulse antennas – it sits on top of a trailer, covered in a green tent.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Close by, trucks and special moving cranes to mount the missiles on their launch gantries are displayed. Also containers for the missiles are shown, together with an example of the Hawk missile itself. The launch order could arrive only from the central Air Force command, except in case of a communication breakdown, when each missile base could decide on its own – at the high risk of making a mistake!

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Farther on, power trucks and other launch systems are displayed besides batteries of Hawk missiles. The launch gantry is smaller in size compared to that of Nike-Hercules, but each gantry launches three missiles instead of only one. The gantry is anchored to the ground, and when inactive it is shrouded in a peculiar rubber-coated eyelid-like bubble, which can be quickly lowered to let the missiles out.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

On the far end of the missile area, you can see an old-fashioned coastal cannon, part of the original fort, used as an illumination cannon in support of larger cannons in the battery.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

One of the naval gun batteries is the first item you meet when entering the actual Stevnsfort fort. The fort was built between 1952 and 1955 for use by the Navy, and is the oldest part of the installation. Together with the Langelandsfort gun battery and command post (see below), it was tasked with monitoring marine traffic along the straits giving access to the Kattegat and the North Sea from the inner Baltic. For the purpose, it was supplied with a huge underground bunker, its most distinctive feature, as well as batteries of naval guns.

The 150 mm guns have an intriguing history. They were made in Nazi Germany early during WWII, for the Kriegsmarine ship ‘Gneisenau’. This was damaged when still in the dockyard, and the guns were re-designated to be placed on the Danish island of Fano on the North Sea coast, as part of the fortifications of the Atlantic Wall. Following the end of WWII in May 1945, the guns were captured and finally found their way to Stevnsfort.

The two-guns batteries were capable of 4-6 shells per minute per barrel, and could reach to the coast of Sweden, thus effectively closing the Oresund strait between Denmark and Sweden if needed. While primarily an anti-ship battery, the swiveling turret could be used to cover the coast, in case of an amphibious attack.

Firing direction was by means of a primary radar station on site, which is still in use, complemented by five other stations along the coast. The shells were loaded with an elevator from the bunker underneath. The guns were temporarily deactivated – but not dismantled – in the 1980s, when Stevnsfort assumed the role of main control and communication post for the southern district of the Danish Navy. Joint exercises with the military forces of the FRG were carried out also here in the final years of the Cold War.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

By the entrance to the underground bunker you can spot several air hatches emerging from the ground, and an example of sea mine. The latter was the primary weapon to interdict traffic on the strait, with gun battery fire being mainly directed against enemy mine-sweepers.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Past the entrance, you need to descend a long stair into the bunker. At the base of the stair is an airlock with facilities for decontamination. The Stevnsfort bunker was most notably the first structure in Denmark to be built to withstand a nuclear attack.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

The bunker is not excessively big, with about twenty reinforced-concrete-padded rooms connected by tunnels carved in the rock.

One of the highlights of this installation is the communication bunker, operative since 1984 in an area formerly hosting a hospital, then shut down when the naval batteries were deactivated. This used to be a highly inaccessible facility during the Cold War. Thanks to a careful preservation, the room looks like it was still in use! Batteries of telex and other communication machines originally in place, monitors and modern imaging technology from the Eighties, together with examples of ciphered messages are all on display.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Next to the communication room, the operation room is even more impressive. Similar to the former, it was constantly manned, and totally inaccessible for non-authorized personnel. The radar monitors can be seen towering over the consoles! Military staff on duty identified and followed all marine traffic in the assigned district, both civilian and military, friends and potential enemies.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Catalogs of existing ships are on display. Several thousands ships were identified and observed from this facility in the days of operation. It is reported that patrol ships from the USSR approached the coast under surveillance about 30 times per year, tasked with familiarizing troops with local geography…

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Another highlight of the visit is the ammo storage for the gun battery previously visited. In the storage, explosive cartridges are placed separately from the shells themselves. There were four types of shells, recognized through a color code – grey for armor-piercing, orange for explosive, green for illuminating and blue for inert.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

The almost-100 pounds cartridges were loaded on an elevator, and lifted up to the battery. A ladder provided direct access from the bunker to the cannons, serving also as an emergency exit.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Other rooms you can visit are sleeping quarters for the 250 men which stationed inside the bunker, until the guns were deactivated in 1981. The fort was capable of sustaining prolonged isolation in case of crisis or war. During the Cuban missile crisis, the Stevnsfort bunker was put on maximum alert for a week, with all men living underground, all accesses sealed.

Cold War Museum Stevnsfort Denmark – Cannons, Bunker and Operations Center

Getting there and moving around

The Cold War Museum Stevnsfort is an international-level museum, to be found 1 hour driving south of central Copenhagen. The official website with directions and opening times is here. Visiting inside the gun battery and the bunker is possible only on a guided tour, where you are given an audio guide in English (also German and possibly other languages) if you can’t follow the Danish-speaking human guide. The guided tour includes also a visit of the missile battery, but this part can be toured also on your own. The guided visit lasts about 1.5 hours, and may turn a little boring in some parts (as usual, the human guide speaks longer than your audio-guide), but it is needed to get access to the most unique parts of the museum. I suggest visiting relatively early in the day, allowing some spare time after the guided tour and before closure to tour the missile part on your own. Free parking ahead of the installation, nice military-themed shop.

Cold War Museum Langelandsfort

This museum has been opened on the premises of a former naval gun installation from the same years of Stevnsfort (see above). Located on the southern island of Langeland, at the inlet of the Belt channel giving access to the Kattegat from the Baltic, it was in a good position to monitor all marine traffic in its sector, as well as for blocking the channel. As a matter of fact, similarly to Stevnsfort, the main target of the naval guns here were minesweepers, for the channel was completely covered with Danish remotely-controlled sea mines, and action of enemy minesweepers would have been necessary before any attack by the bulk of navy forces.

The main naval force in Langelandsfort was constituted of four naval guns, mounted on swiveling turrets, and a fire control bunker which in non-crisis time was used to keep trace of all marine traffic in the sector. The fort was complemented with anti-aircraft defensive positions, a bunkerized power station, and ‘softer buildings’, including barracks. Except for the latter, everything has been restored and can be visited. One of the naval batteries has been restored completely to its original form including the mechanisms underneath, whereas at the base of the other three batteries you can find exhibitions about various aspects of the Cold War – they are all pretty well studied, rich and interesting.

The command bunker is the first construction you meet. The building is from the 1950s, and it shares many aspects with Stevnsfort, though this is much smaller. You can see sleeping quarters and a kitchen, which would be used especially in case the fort was sealed, i.e. in case of high alert or war.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The control rooms are three. Two are for tracking marine traffic in the marine district of the Belt, and also for coordinating air operations from other military installations in Denmark. A radar antenna and an observation tower outside, likely complemented by similar gear in the area, provided a complete real-time picture of the civilian and military traffic in the sector. It is reported that ships going to Cuba with SS-4 nuclear missiles and related supplies were spotted in these rooms months before that material was photographed by the US, when the crisis broke out.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The third control room is the fire control room for the whole fort, coordinating fire from all four gun batteries. Fire control was by means of a very interesting piece of machinery, a fully mechanical computer, taking in atmospheric data like temperature, humidity, wind direction and speed, and target data. No electricity was needed except for lighting the goggles of this analog computer! A similar item was present in Stevnsfort, but I could not see it during my guided visit.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

In an adjoining room you can see a perfectly restored communication facility, with ciphered messages hanging on the walls, as well as original transmission machines and early computers. There is also a personal study room for the commander of the post.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Besides the control bunker you can find an anti-aircraft position, centered on a four-barreled anti-aircraft gun. Similar to all others, the small bunker underneath could be manned and sealed in case of war.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The cannon battery closest to the control bunker has been restored completely, including the bunker underneath. The 150 mm guns, one per battery, were made in the final years of WWII by Skoda works in Plzen, in the then-Nazi occupied territory of Czechia. They were originally intended by the Wehrmacht for the Atlantic Wall in Denmark, but they never became operative there. Instead, they ended up to be installed by Denmark to counter a Soviet threat on the Baltic.

The mechanism for supplying cartridges to the cannon is similar to that in Stevnsfort, with an elevator lifting the explosive charge and the shell separately to the level of the gun. However, here the storage bunker is just beneath the cannon, and the lift does not carry the cartridge directly inside the turret, but to a hatch in the reinforced wall besides the cannon – something similar to some of the smaller cannon batteries of the Atlantic Wall built by the Germans.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Inside the bunker you can see the ammo storage, as well as a sleeping compartment for the 15-men crew needed to operate the cannon.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Some example shells have been preserved, with colors corresponding to different functions of the shell (see Stevnsfort above).

The cartridge elevator room is very small, and access is from both sides. Explosive and shell came from opposite directions, each from the corresponding storage room.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The bunker under the next cannon battery has been dedicated to the analysis of the threat from the Danish perspective. Here you see copies of the Soviet plans to invade Denmark, as part of an operation to conquer central and northern Europe lightning-fast in case of an open war against the West. Among the most striking items, you can see detailed Soviet maps covering all regions of Denmark – with city names and all writing in Cyrillic!

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

There is also a nice collection of ordinary weapons and military supply from the Eastern Bloc, and especially from the neighboring German Democratic Republic. A very special feature is an example of the ‘Blücher decoration for valor’, a medal created by the GDR to be attributed to individuals for actions of exceptional courage in the defense of the GDR, and to be assigned only in case of war – thanks to the Cold War never turning ‘hot’ for the GDR, nobody could be awarded this decoration.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The next battery is dedicated to espionage and spy gear, with many examples of James-Bond-like trinkets, actually used by both enemy and Danish spies. Machinery for ciphered communication, once considered hi-tech, is also on display, together with maps used by a Danish spy visiting the Polish coast, and satellite imagery of East German/Soviet airbases.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The exhibition in the last battery is about the Cold War and society, and is full of old photographs of pro-Soviet protesters in Denmark, spies, famous characters of the Cold War, momentous events taking place in Denmark during the Cold War and so on. Most notably, there are also many artifacts from both Denmark, the Eastern Bloc and the USSR, including medals, posters, portraits and much more.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Similar to the control bunker, the power station has been preserved in its original condition. Three diesel engines could provide power to all bunkers in case of war or failure of the grid for whatever reason. Immediately outside the entrance to the power station bunker there are apparently some suspended showers…

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The large area of Langelandsfort has been selected also for the exhibition of a submarine, a mine-sweeper and two aircraft! The submarine ‘Springeren’ was used by Denmark in the 1990s and early 2000s, but it was built much earlier and operated by the Norwegian Navy. Sadly, after the retirement of ‘Springeren’, the Danish Navy shut off completely its underwater branch. The ship is a small conventionally powered attack submarine. The interior is apparently pretty modern with respect to older German or US WWII U-boats.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The submarine features six torpedo tubes.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The mine-sweeper has the appearance of a small conventional boat, but with room for a crew of several men. It is hosted in a hangar together with examples of sea mines – apparently US models.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The two aircraft are a SAAB Draken of Denmark and a MiG-23 of Poland. They represent some of the most advanced aircraft of these opposing countries at the height of the Cold War. Both exemplars are well preserved inside hangars protecting them from the weather and sunlight.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Another interesting sight is a reconstruction of a civil defense bunker, with much original material, including packs of ration cards already prepared for the population in case of war. In an adjoining room you can see a reconstruction of a bunkerized broadcasting studio – the national TV channels were tasked with providing updates to the population in case of an attack, hence a similar facility was prepared in the basement of the TV headquarters.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Close to the ticket office, you are offered a very well-designed exhibition tracing the timeline of the Cold War, with some clever text and many pictures, some of which rather uncommon – really worth spending some time on, before or after visiting the museum.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

There is also room for temporary exhibitions, in a hangar which includes an original section of the Berlin Wall.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

The building of the ticket office is also interesting. From the back of it you can get access to a smaller exhibition about travels to the DDR (the native acronym for the GDR), with everyday items, old Interflug boarding passes, and some incredible postcards – apparently, modern Soviet-style housing and heads of Marx were the items that GDR postcard-designers liked most… Fragments of the Berlin Wall are also on display.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Ahead of the entrance there is an old and pretty big hammer and sickle, originally from a Soviet ship. The commander threw it outboard when the Soviet Union officially ceased to exist. It was collected by a Danish sailor and ended up here. Nearby you can see a reconstruction of the Berlin Wall, and an original Trabant crossing it.

Koldkrigsmuseum Langelandsfort, Bagenkop – Cold War Museum Denmark – Cannon Battery, Bunker and Operations Center

Getting there and moving around

The Cold War Museum Langelandsfort is located close to the southern tip of the island of Langeland, which is connected with bridges to the major island of Fyn, where Odense can be found about 1-hour north of the museum by car. You can move around the museum on your own, there are several panels with explanations. Most panels have at least a quick translation in German and English. All presentations are very well designed and maintained. Visiting may take at least 2 hours for an interested subject, and even more especially if you are taking pictures. Free parking ahead of the entrance, and picnic area nearby. Official website here.

Aalborg Defense and Garrison Museum

This museum was opened in the year 2002, in the hangar of a seaplane base constituted by the occupying German forces in 1940. The base was potentiated in more instances during WWII, and a half-interred command bunker similar to those of the Atlantic Wall was added.

Aalborg has been a military post for centuries, therefore the museum is centered on several aspects of war and military life. Of course, the majority of the artifacts on display date from WWII and the Cold War period.

The hangar hosts a small collection of aircraft, which capture your sight when you get in. Most notably, there are a venerable F-84, an F-86, and somewhat older T-33 and Gloster Meteor.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Close by, you can find a more modern F-104. Jet engines of American make from some of these aircraft have been taken out of the airframes, and put on display separately.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Again in the center of the hangar you can see a Hawk missile system, including the missile battery and movable power and control trucks. Also anti-aircraft guns and searchlights from various ages are on display.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Items from WWII include a nice exhibition of locally-collected gear used by the Danish resistance movements. Supplied by the Allies from the air, they managed to build several types of bombs, mines, and so on, made to disturb and damage enemy transports, or to kill enemy staff in well programmed para-military actions.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Memorabilia include the engine of an US B-17 bomber, sadly downed over the Baltic during the crew’s final mission, the original Luftwaffe eagle once standing on the building of the local German air command, and a Nazi flag weaving on some public building in town in the years of the German occupation.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

There are also many photographs from the area from the war years, and reproductions of German maps and local newspapers. The latter tell about relevant facts taking place during the war, as reported by the local media. There are also diplomas of merit issued by the US and Britain in favor of a local citizen, member of the resistance.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

A part of the exhibition is about civil defense. Similar to the US, Britain and other countries during the Cold War, this service was activated to prepare the population to a nuclear war scenario, and to provide shelter and a chance of survival, by means of bunkers and deposits of supplies. Here you can see a reconstruction of such a shelter, and items which used to be stored in preparation for survival in the nuclear winter.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

There is also a nice collection of light weapons from local firms, uniforms and communication rigs.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

A few uniforms and technical gear from the current supplies of the Danish military are on display as well.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

In a room to the side of the central hall, you can find uniforms dating from WWII, including German stuff. The story of a Dane coming to the US and fighting for the US Army is also told in a corner, also through some memorabilia.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

On an elevated platform you can find an exhibition about the Cold War. This is mostly made by panels retracing the history of that confrontation over the decades. Among the most peculiar items on display, a copy of the invasion plan studied by the Soviet in case of a sudden war with the West. That plan included the rapid conquer of Denmark, due to its strategically relevant position. A copy of a Soviet-made map of Aalborg in Russian, needed in case of war, is another example of the unique artifacts on display.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

This special Cold War exhibition is completed with a set of field and anti-aircraft weapons from various ages of the confrontation.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Other rooms around the main hall display modern uniforms, NATO-related material, military supply from various ages and even a throne used by the Queen of Denmark on an official visit.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

In an adjoining smaller hangar you can find a rich collection of trucks and weapons with various – not only military – functions.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Outside, a highlight of the museum is the former air command bunker built by the Germans. This has been filled with memorabilia from the Nazi occupation period. An unusual and little-known story is told here, about the German refugees from Eastern Prussia, a region loosely coincident today with the part of Russia around the town of Kaliningrad (ex-Konigsberg). This area used to be part of Germany since before WWI, and it remained under the Weimar Republic, even though separated from German mainland. Neighboring Lithuania was annexed to the Third Reich before WWII – similar to Sudetenland – on account of the proximity to that region, with the excuse of a significant German group living in Lithuania. In 1939 the Germans re-gained control over northern Poland, and the two regions of Prussia were reunited in the Reich.

Following the victories of the Soviets in 1944 and the ensuing landslide-march towards Berlin, Eastern Prussia was lost to the enemy. Refugees escaped to mainland Germany, and the administration of the Reich sent these folks in several areas relatively far from the front – including a significant number to occupied Denmark, and especially in the hangars in Aalborg, where the museum is today. So the hangar acted as a hospitality center for the refugees. This was something strange though, for the refugees were not local nationals, but instead enemies. This led to a controversy soon after, when the war ended. In the event, most of the refugees returned to their land of origin, only to find it permanently occupied by the Soviets. Some handmade artifacts of these German refugees can be seen on display in the bunker.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Finally, a very good collection of tanks, field guns and movable howitzers from various countries including the Eastern Bloc and mainly from the various ages of the Cold War can be admired on the museum apron. For the most part, these are reportedly kept in working condition.

Aalborg Forsvars- og Garnisonsmuseum – Defense and Garrison Museum – WWII and Cold War Weapons – Denmark

Getting there and moving around

The museum is located close to central Aalborg, on the waterfront. You can visit it totally on your own. Some of the exhibitions are described in more languages, but some parts are in Danish only. Nonetheless, the visit can be very rewarding for experts and for the kids as well, thanks to the chance to touch many of the artifacts on display. A two-hours time may be enough for having a look, more time is required for a more in-depth visit or if you want to take pictures.

Convenient parking just ahead of the entrance. Website with full information here.

Danish Museum of Flight

This fantastic collection of aircraft can be found next to Stauning Airport, on the west coast of Jutland, at the level of the Ringkobing firth. This is by far the largest aircraft collection in Denmark, and the reference air museum in this country.

The exhibition is well designed and rich, and it covers both the civil and military branches of aviation. Furthermore, a good half of the aircraft appear in fully airworthy conditions.

There are three thematic hangars. In the first you can find civilian aircraft from various ages, smaller sport aircraft and military trainers mainly from the inter-war period or the late 1940s. Some of them appear airworthy.

Most notably, there is the front part of the fuselage of a Douglas DC-7, formerly in service with the national carrier SAS, still on business today. The cockpit and the crew compartment are well preserved. The analog instrumentation adopted on this plane, which dates from 1957 and represents the last and most advanced of the Douglas propliners, is abundant and remarkably sophisticated.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Another unique aircraft on display is an Aerospatiale Corvette, an executive jet by the same French airframer who participated in the Concorde project. You can also board the plane.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Similarly rare today is the DeHavilland Dove, a British-made short range liner from the early Cold War period. Similar aircraft, cheap to operate, went on flying well into the 1970s in many countries. Here you see an exemplar in the colors of Cimber Air.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Among the trainers, you can find a DeHavilland Tiger Moth and a Chipmunk from the same manufacturer. Less common aircraft include a DeHavilland Hornet Moth, which apparently spent most of its flying time in Kuala Lumpur, and a nice Bucker Bestmann, a German trainer adopted and license-built also in Sweden.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Despite never adopted by the Danish military, a V-tailed Fouga Magister French trainer apparently found its way to here. It was reportedly flown in private hands by a Danish professor, before being donated to the museum.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

In the first hangar are also examples of Danish aircraft production, including the reconstruction of an early prototype by a local pioneer. Propellers and dismounted engines and systems, likely used for training purposes in the past, are an interesting part of the exhibition too.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

A huge collection of model engines, some air traffic control consoles and airport trucks complete the exhibition in the first hangar.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

The second hangar is mainly devoted to aircraft manufactured in Denmark. Most notably, the Skandinavisk Aero Industri – abbreviated in SAI – specialized in trainers and small transport in the inter-war and WWII period, and knew a good national and local international success between 1937 and 1954, when it disappeared – and with it basically also the Danish aeronautical industry.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Some of the aircraft on display are unique exemplars, the last witnesses of this interesting story. Not all aircraft here are from this manufacturer though – an ubiquitous Piper Cub in its distinctive yellow colorway can be found as well, together with a Supermarine Spitfire. Also here, most aircraft appear to be in airworthy conditions.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

In the last hangar, which despite being the largest one, is the most crumpled, you can find military aircraft retracing the history of the Danish Air Force supply. The aircraft here are all from the Cold War period, hence giving to this hangar a historical connotation. This part of the exhibition is also particularly nice, as you can walk close and beneath the aircraft, an ideal setting for getting pictures of smaller particular features.

The variety of present aircraft is very interesting, and reflects the close bounds of Denmark with the US and Britain. Aircraft from the early Cold War include Lockheed T-33, a North American F-86, and two different versions of the Republic F-84.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

An exemplar of the latter is supplemented with JATO – Jet Assisted Take-Off – bottles under the fuselage. The mountings of the underwing rockets on the F-84 and of the belly rockets on the F-86 are really unique examples of Cold War technology!

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

A big Consolidated Catalina amphibious aircraft towers on all others in the hall, while a Douglas C-47 transport in excellent conditions is preserved in a corner, with an interesting ski system mounted on the landing gears.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

British aircraft from the same early era include a Gloster Meteor and what appears to be a pretty rare Fairey Firefly. Another US design is a T-6 trainer, to be found under the wing of the Catalina.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

More recent designs still from the Cold War include a Lockheed F-104, a British Hawker Hunter and a Swedish SAAB Draken.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Especially the configuration of the latter – both the general configuration and the arrangement of the landing gear and wing pylons – is really unique, reflecting a different yet interesting school of aircraft design.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Rather uncommon out of the US, a North American F-100 Super Sabre is also on display, with a foldable Pitot boom.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Finally there are a Hawk missile battery, a movable command center and service trucks.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Modern aircraft are represented here by an F-16. There are also two helicopters of US make, closing the collection.

Danmarks Flymuseum Denmark Museum of Flight Jutland Skjern Cold War Planes

Getting there and moving around

The museum is located between Stauning and Velling, two small villages on the inner coast of the Ringkobing firth, western Jutland. The facility is modern, with a large free parking and a picnic area. It is located on the border of a local airport, immersed in nature – a very pleasant location. The museum requires about 2 hours for an interested subject, 2.5 if you want to take pictures. Website with full information here.

Soviet Depots for Nuclear Warheads in the GDR

Despite their great destructive potential and strategic relevance, nuclear assets were deployed far from the ‘centers of power’ in Moscow and Washington by both the USSR and the US. As the front of the Cold War was especially ‘hot’ along the border between the Warsaw Pact and NATO Countries in central Europe, large arsenals of nuclear weapons were deployed to the area, on both sides of the Iron Curtain, and in several instances over time.

On the western side this was not hidden and led often times to protests in Countries like the UK, West Germany and Italy, so that the history of the presence of a nuclear arsenal in those Countries can be traced with some accuracy, albeit not easily. Conversely, much less is known about the deployment of Soviet nuclear arsenals over the territory of the former Eastern Bloc, making this segment of Cold War history especially mysterious.

History – in brief

In this Cold War scenario, the German Democratic Republic (GDR, or DDR in German) received special consideration by the Soviets. Thanks to its advanced position in Europe and the local, much trusted ‘hardcore’ communist regime, the USSR planned the deployment of early strategic missiles – SS-3 Shyster and SS-4 Sandal – starting already in the late Fifties, the years of Khrushchev. Traces of an actual deployment exist in Vogelsang and Furstenberg, about one hour driving north of Berlin (see this post about Vogelsang, and this about the mysterious deployment of missiles in the area).

Later on, in the early years of Brezhnev as leader of the USSR, it was decided that for a prompter and more flexible response in case of an attack, nuclear warfare especially for tactical use should be deployed outside of the USSR borders, to Countries in close proximity with the West. On the other hand, strategic warheads and missile systems could be withdrawn to within the USSR, as more technologically advanced intercontinental ballistic missiles had become available, making a hit of a foreign objective possible even from deep inside the Soviet borders.

Consequently, deployment of air launched nuclear warfare started in selected Soviet airbases, which were really not in any shortage in the GDR – considering both the national air force (NVA) and the Soviet aviation, the DDR used to be one of the world’s top countries in terms of airbases per square mile, or per resident. You can see several posts on former Soviet bases in the GDR on this website (look here, here and here).

For military corps not operating from airbases – especially missile brigades – the headquarters of the Red Army in Moscow deemed necessary the deployment to the GDR of nuclear warheads for tactical or theater missiles.

Two depots were built anew in dedicated installations specifically for hosting such warheads. One was in Stolzenhain, codenamed ‘Objekt 4000’ and sometimes referred to as Linda (the name of a village nearby), close to the highly-militarized area of Juterbog (see this post) and Kloster Zinna, about one hour driving south of Berlin. The other was again close to Furstenberg, and named Lychen-2, and codenamed ‘Objekt 4001’.

The nuclear bunkers in Stolzenhain and Lychen were payed for by the GDR – through a governmental agreement with the USSR – which always detained official property of the facilities, and were built by German workers, around the year 1967. Once ready, in 1968 the bunkers were handed over to Soviet staff, and the corresponding areas totally closed to non-Soviets. The bunkers, as other similar facilities in other Countries of the Warsaw Pact, communicated directly with Moscow, as similarly to the US, only the top of the command chain could authorize the use of nuclear forces.

The facilities were kept running until the end of the Cold War. Control was officially given back to the agonizing GDR in 1990, the Soviets having transferred all valuable material to the (agonizing) USSR.

Here the story splits for the two installations. While the Lychen bunker has been selected for interment, the installation largely being demolished around 2015, forgotten and reclaimed by nature, as of 2019 the Stolzenhain bunker is in a far better condition, apparently in private hands, and albeit plans for it are sadly similar to Lychen, it may be still in time to be turned into a unique, world-class museum.

About this post

This post covers both Lychen-2 and Stolzenhain bunkers. The former was explored in the summer of 2019. The latter was explored a first time in 2019, and in a second instance with the guidance of its owner Manfred van Heerde and the nuclear scientist and historian Reiner Helling in 2021. As the Stolzenhain installation is still in a relatively good shape, you can also get an understanding of what the inside of these bunkers looks like, their design and specific features. Pictures of this installation from above can be found in another chapter (see here).

Objekt 4000 – Stolzenhain

The Stolzenhain bunker, aka ‘bunker Linda’, due to the name of a nearby village, is a perfect specimen of this type of construction (codenamed Monolith-type – see also this post for similar sites in nearby Poland, including one open as a museum). It is composed of two adjoining sub-parts – an area with larger barracks and ‘soft’ constructions, and a larger area were two twin bunkers for warheads are located, together with smaller service buildings and smaller service quarters for the troops. The two areas are arranged along a north-south direction, with the bunker area north of the barracks area.

Today, access to the barracks area is mostly interdicted – you may venture in by foot, but there is a gate which does not allow getting in by car, despite the relatively good condition of the road. The premises are in private hands, and some demolition/reconstruction/conversion works are being carried out here. There is also a service building, looking like a private residence, built in recent times.

Main Gate and Outer Buildings

The main access road features typical prefabricated concrete slabs, found in most Soviet/communist installations everywhere in eastern Europe. Halfway between the external gate and the barracks area, traces of an external wall can be found, with a couple of ‘welcome stones’.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

A closer look to the slabs reveal a rather poor quality material used for manufacture. Writings are excerpts of the Soviet constitution, presented as mottoes in Russian, with some communist symbols.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The barracks and some softer constructions date from the Seventies – the frieze on the sidewalls of the buildings tells it quite clearly. The area is protected by a concrete wall, bearing a probably original greenish camouflage.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

In the years of operation, there used to be four large apartment blocks aligned in a row, just ahead of the entrance to the area of the barracks. These buildings were for the officials and their families. While still inside the external fence of the base, these apartments allowed more privacy and convenience, forming a de facto little Soviet village in the GDR, segregated from the surrounding German community. This housing has been completely demolished today. However, some trace of correlated ‘civilian’ facilities can be found to the south of the barracks area.

In particular, a swimming pool was built at a certain point in the history of the base, and it is still in a relatively good shape. Changing rooms for men and women are still there. A tall springboard and starting blocks still face the pool, which is apparently watertight, despite the greenish water not being really attractive!

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The pool features an outer fence, with a service gate bearing a characteristic Soviet ‘diverging rays’ motif.

Another facility put specifically for comfort in this area is a sauna/bathing house, a widespread Russian tradition. The sauna building in Stolzenhain features several smaller adjoining rooms, with pools, sauna/Turkish bath areas, a central heater, as well as more general purpose sitting rooms with fireplaces. A video studio was also featured in this multi-functional building.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

An interesting specimen of Soviet naive art, some frescoes adorn the walls of some of the rooms, with subjects ranging from sea life to women performing ‘spa activities’.

Still outside of the innermost military part, yet inside the external fence of the base, a training ground is to be found to the east of the military area, not too far from the spa building. A walk in the trees along the inner perimeter of the wall of the base is needed to reach this part. A control building with an observation post on top features plenty of instructions for tasks to be performed in a training exercise – in Russian!

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Close by, a shooting range for light weapons (rifles, guns) can be found, again with precise indications on the distances to be taken from the target, marked by colored lines on the ground.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Back to the gate to the military barracks area and stepping inside, among the few surviving buildings is a former gym. Despite used as a storage today, the larger hall is clearly a former volleyball/basketball court. A referee chair is still hanging from the sidewall, and sport-themed frescoes decorate the walls.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Former hangars for trucks or technical vehicles can be found in the eastern part of the former barracks area, similar to traces of a fuel pump. As said, most of the former buildings here are now gone.

A special feature in the barracks area is a manhole with traces of a set of cables, pointing towards the highly secretive and guarded bunker area. Communication is of paramount importance for military practice. In the case of nuclear depots so far away from Moscow, a cable connection was implemented not to loose contact under any circumstances between the Soviet headquarters and this peripheral, yet so valuable facility. Pressurized cables were used, such that when an attempt to severe or intercept cable signals was carried out by the enemy cutting the cable, the external jacket was pierced, a loss of pressure was sensed, and an alarm was triggered immediately. Similarly, in the case of an accidental degeneration of the ground where the cable ran, the pressurized jacket was pierced triggering an alarm, allowing the technicians to repair the cable and restore contact.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

An old and forgotten Soviet standard service container, typically transported by truck, can be found close to the manhole totally invaded by vegetation. From here, a view to the perimeter concrete wall around the innermost part of the site can be easily seen, with clear traces of camo paint.

Bunker Area

The area of the bunkers is fortified with a concrete wall with barbed wire on top running along all its perimeter. The size of the bunker is immediately apparent from above – you can look at some aerial pictures from a dedicated flight over the area, see this report. There is a gate connecting it to the barracks area. The only other gate to the bunker area, located north on the other end of the complex, opposite to the first gate, is partially obstructed.

For its entire length, the external wall of the bunker area is almost perfectly preserved, and abundant traces of camouflage can be easily spotted all along.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Inside the wall, you soon find a fence of barbed wire with concrete posts, again standard for Soviet military installations. Some sections of the barbed wire are very well preserved, albeit rusty. The overgrown vegetation looks like the only difference between now and the years when the bunker was in operation!

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Inside the barbed wire fence, you find traces of an exceptional system of trenches and turrets, which should have granted protection to the innermost part of the complex – the storage bunkers. There are turrets of many kinds, including one which looks like the dome of a tank, re-used for the purpose – a feature also of the Atlantic Wall and the Salpa Line (see here). Such a degree of protection is extraordinary also with respect to other military installations. Abundant traces of barbed wire-holders along the tranches can be easily spotted. The site was clearly considered as an objective of special value, to be seriously defended in case of an attack from the West.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Close to the center of the large fenced area, you soon reach the bunkers (there are a western and an eastern bunker, described below), which despite being mostly underground, feature a small mound on top which allow spotting them from the distance.

Western Nuclear Storage Bunker

Access for the warheads is at the level of the ground. There are two large tight doors corresponding to the two ends of the main hall of the bunker. Below you can see a 3D sketch of the bunker, from a placard found close to Objekt 4001 (the Lychen bunker), describing the inner layout.

Abandoned Soviet Nuclear Warhead Bunker Lychen-2 Objekt 4001 East Germany

By one of the entrances to the bunker is a small loading/unloading platform for two trucks. The apron connecting the platform to the bunker door used to be covered by prefabricated roof tiles – rich in asbestos – and covered with artificial vegetation, of which some traces remain.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The area is overlooked by a firing turret, seating above the front of the bunker.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The external tight door gives access to an airlock, a small square compartment closed to the opposite end by another identical door. This is explained in view of the need to protect the innermost part of the bunker from attacks by means of high-yield weapons. A similar architecture can be found in a Soviet nuclear depot in Szprotawa, Poland (see this post).

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

From the airlock you get access to a suspended platform, from which you can appreciate the storage facilities of the bunker. There is a main hall, where the warheads were lowered by means of a motorized crane from the suspended platform down to the underground level. From there, they were moved to one of the four long storage chamber, all accessible on the same side of the main hall.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Temperature and humidity of the main hall and storage rooms were perfectly controlled. Ventilation pipes and an impressive array of hangers for heat exchangers can be seen in the main hall.

Access to the underground floor from the suspended platform is only possible with a ladder, passing through a narrow hatch – as usual, it’s hard to understand why the Russians (or the Germans in this case) built passages so narrow and uncomfortable, considering they are not among the shortest human types on Earth… – see this post for another brilliant example…

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The storage rooms are very long, and traces of strongpoints for anchoring the warheads safely on ground can be seen surfacing on the floor. The doors between the main hall and the storage rooms, where present, don’t appear to be tight. Most writing is in Russian, but some labels are in German. This can be explained with the bunkers being realized by GDR personnel, upon requirements by the Soviets.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The blue cabinets and piping in the pictures are part of the warhead monitoring plant. Each warhead – the actual number is part of the mystery, but there used to be several tens of them in each of the two bunkers on site! – was kept in a sealed shell, to keep sensitive nuclear material precisely in the required climatic condition. Constantly checking the condition of the warheads was part of the duty of the bunker personnel. For the task, each warhead was moved to the hall and connected to the piping, to take measurements of temperature, pressure, atmospheric composition and similar parameters. In case of an anomaly, the warhead was resent to a major technical facility in the USSR (in particular, in Belarus for the Stolzenhain warheads), for fixing.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

To the opposite end of the main hall from the entrance is another identical entrance, with a suspended platform and an airlock. In the case of this bunker, the most external tight door to the far end has been taken off its hinges and put on the floor, whereas that between the airlock and the main hall has been permanently shut.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Back to the main hall, on the opposite side of the storage rooms on the underground floor, it is possible to access a service area, with several smaller rooms connected by a narrow corridor. The function of each room is not difficult to argue, and looking at some details it is possible to make some easy hypothesis.

Electric actuation for the ventilation system may be the function of a first room.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

What looks like a kind of hydraulic pumping/water filtering system is located next door, split over three adjoining rooms. The system has been pulled down to the ground, but it is not severely damaged.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Next you can find a reservoir for water, placed in a room close by, painted in green and highly damaged.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Going further along the corridor, you can find a toilet. Poor drainage – don’t forget this floor is entirely underground – meant that the troops spending their shift in the bunker did not use the toilet much, and climbed out of the bunker for their necessities.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Further on, you can see a room which is probably a sleeping room for the troops stationed inside the bunker. A heat exchanger and traces of a sink on the wall may support this theory. Air ducts leading to the surface can be found in recesses close by.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

A room with traces of electric material and an electric panel outside may have been an electric power control facility, maybe even a cable communication facility.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Further on, you get access to a power station, where clear traces of a diesel system for supplying electric energy to the bunker can be found. A big reservoir painted in yellow may have been the diesel fuel tank. A stator of an electrical generator can be seen on the floor. Parts of a diesel engine can be found, and what may have been tanks for lubrication oil can be seen on the walls. As it often happens with defense bunkers – even for larger defensive forts since before WWII – the installation was usually powered from the outside grid in peacetime, but it had to be capable of staying active in case of an attack and failure of the external grid. Hence backup generators can be found in most underground bunkers since the 20th century. Especially in the atomic age, when a nuclear attack on the installation was considered a potential scenario, a stress was put on this type of countermeasure.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The diesel engine is earmarked with a Soviet label, witnessing its origin! Similarly, electric motors and components scattered on ground – part of the ventilation system – are ‘made in CCCP’.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Traces of lubrication oil can be found on panels on the floor. Between the power station and the main corridor, a side door gives access to a ladder going up. This was likely the ‘normal’ pedestrian access to the bunker.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

A few more service rooms can be accessed from the main underground hall, through doors on its short sides, under the suspended balconies. There were mechanical workshops, but also facilities for dealing with contaminated or poisonous material, in particular that of nuclear warhead triggers. This is further witnessed by traces in the eastern bunker (see below), and by special valves installed on the ventilation system in those rooms.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Getting out and climbing on top of the bunker, it is possible to spot several air hatches for the ventilation system (including that of the power station), as well as a metal cabin covering the ladder giving access to the service rooms in the bunker – the ‘normal’ pedestrian access cited above.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

A loading/unloading facility, larger than the one on the other side and with platforms of different sizes numbered from 1 to 4, can found also by the other gate of the bunker, which as noted is sealed.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Also here, an asbestos-rich roof can be found in the truck docking area, but there is no superstructure covering the apron leading to the door of the bunker.

Eastern Nuclear Storage Bunker

A large concrete road forms an ‘8’ around the two nuclear storage bunkers. The bunkers are identical, but for protection the eastern bunker was built tilted by 90° with respect to the western one – this way, it was not possible with a single attacking wave to hit the entrance gates of both bunkers.

The gate on one end of the bunker has been partially interred. The large apron leading to the truck loading facility is not covered. Traces of a fire emergency system can be found. Many hatches can be seen on top of the bunker, not all well conserved. One of them carries the curious inscription ‘Baku’, the capital city of the former Soviet Republic of Azerbaijan, written in Russian – as elsewhere in Soviet military installations, maybe the troops stationed here marked the place with the name of their city of origin (see this post).

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The bunker is slightly better preserved than the western one. The motorized cranes can be see on top of the main hall – nominal capacity is 32 tonnes.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The array of heat exchangers for temperature control on the side of the hall is clearly visible. A pressure gauge dates back to 1967. The storage rooms keep trace of a ventilation system, yet today humidity is damaging the inside of the bunker.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

An exploration of the service rooms, accessible from the main hall opposite the storage rooms, reveals a water pumping/filtering system and a water tank in their original positions.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The toilet, complete of toilet brush, is placed on top of a platform – the composition is so perfect that it looks like a weird ‘monument to a toilet’!

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Here the air pumps are better preserved than the in the western bunker, with fans still in place and air ducts pointing upwards to the roof of the installation.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

A room possibly for the shift on duty, with a heat exchanger and sink, features a supporting structure possibly made for beds. The electric panels in the adjoining room confirm its function as a control center for electric supply.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Before reaching the power station at the far end of the service corridor, a side passage gives access to a room with bulky air filters. This looks very similar to the filtering system of other military installations elsewhere – see this post for instance. Big greenish canisters are still there with writings in Russian. These were needed for survival inside the bunker, in case of an attack with nuclear or chemical weapons, which would have made outer air poisonous.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The area of the power station is similar to that in the other bunker, except the diesel engine, which is somewhat in a better shape. A big radiator, looking from an old-style truck, has been put alongside a large fan. More radiators can be found in the room, which is also stuffed with air ducts in a bad shape and tanks.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

The smaller service rooms accessible from below the suspended platforms are basically empty, except one with a transparent case, likely for manipulating poisonous material. This was required for older-style nuclear bomb triggers. Soon after the bunker was built, triggers were redesigned, and this room with its facilities was no longer needed. Holes for thick rubber gloves, and even remains of the gloves themselves, can be clearly spotted. The ventilation system in this room features particular valves.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Outside on the far end you can find a docking station for trucks. This has been used more recently as a deposit for asbestos tiles, and venturing should be avoided. On top of the bunker, the metal case with the ladder descending into the underground part, as well as the ladder itself, have been demolished to hamper access.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Other Buildings

In the premises of the fortified bunker area are also other smaller service buildings. Their function is hard to guess at a first glance. Most of them display writings in Cyrillic.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

One of these smaller constructions contained ‘poisoning charges’. These were special ‘weapons’ which could be put on the shell of the warhead and, when triggered, were capable of making it totally inert and ineffective. This was an extreme emergency move, in case a capture of the nuclear warheads was deemed possible due to enemy action. The name of the person responsible for this special action is painted on the gate of the storage.

A low-profile building with a curved roof, not far from a softer construction dating to the 1970s, looks larger and with a mainly pedestrian access. This was a storage for light weapons.

Turrets and defensive buildings are abundant, and all are connected by concrete roads which look pretty good in spite of the decades of disrepair.

Closer to the wall of the inner part, hatches giving access to underground bunkers can be spotted, when exploring with accuracy. These underground bunkers, service rooms or resting rooms for the many troops constantly guarding this installation, are of different size.

A first one, rather convenient, is made of concrete. Nothing remains inside, except traces of a Soviet-style electric plant, made with a questionable safety standard…

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Another is made of prefabricated corrugated tubes, with a sealed entry hatch. This is rather well-preserved, with berths, a stove and a small living area, all accessible via a corridor from the outside.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Finally, close to the barracks area described above, but still inside of the innermost part of the installation, is the access to another underground bunker. Here many smaller rooms, including communication rooms of great importance for triggering actions in the bunker area, are located along a straight tunnel. In the origin, the tunnel went all the way to the barracks area, passing under the fences and wall separating it from the innermost bunker area. The outer entrance was clearly deceived for improved safety, and today it is totally gone.

Abandoned Soviet Nuclear Warhead Bunker Stolzenhain Objekt 4000 East Germany

Getting there & moving around

As the place is private property, no detail will be provided concerning access. Moving around the area is dangerous, due to difficulty of access, proximity with local activities and residents, bad phone signal for emergency, plus tons of rusting material, barbed wire, pits, pierces in the ground, asbestos, slippery soil, etc. scattered over the area. The bunkers are wet and completely dark inside. Obviously, the fact that nuclear ordnance and diesel fuel used to be stored there does not help making the place healthier.

That said, the place is in a fairly good shape for the age and vicissitudes, and hopefully it will be at least partly restored and opened to the public in the future, once suitably sanitized.

If you are interested in a legit visit of a Monolith-type bunker, you may consider going to Podborsko in nearby Poland. See this post for pictures and info.

Objekt 4001 – Lychen-2

The Lychen bunker was built on a design basically identical to that of Objekt 4000. The only difference was the orientation, this time along an almost east-western direction, with the ‘softer part’ towards the east and the bunkers to the west.

Historical pictures – actually, even from the early 2010s, when the installation was still mostly untouched – show a very peculiar monument with the head of Lenin and other emblems, marking the entrance to the bunker area.

Today this installation has been completely wiped out. All soft constructions have been demolished, and the ground has been leveled – there is basically no trace of them at all. The monument is gone too. The turrets and protection systems have totally disappeared, similarly to the truck loading and unloading stations.

Abandoned Soviet Nuclear Warhead Bunker Lychen-2 Objekt 4001 East Germany

Even more surprising is the great care taken to make all walls and fences disappear completely. There are no walls, nor barbed wire fences. What you can still – barely – spot is where the external wall and inner fence used to be, as vegetation has not yet covered the perimeter.

Looking with great care, and knowing where it used to be, if you are lucky you may find scant remains of barbed wire on the ground.

Abandoned Soviet Nuclear Warhead Bunker Lychen-2 Objekt 4001 East Germany

Instead, the concrete access road and inner service roads are still there. In the middle of the ‘8’ shaped road around the two bunkers, a placard with information has been put by the regional administration. The placard concludes saying that being there should ‘provoke thoughts’ – for instance, why wasn’t this installation preserved somehow for posterity, instead of leaving it slip into oblivion?

Abandoned Soviet Nuclear Warhead Bunker Lychen-2 Objekt 4001 East Germany

The bunkers, made to withstand a nuclear blast, are too expensive to be demolished. However, the doors have been completely sealed and covered with land and concrete. The camouflaged concrete fronts of the bunkers are the most visible trace of Objekt 4001.

Abandoned Soviet Nuclear Warhead Bunker Lychen-2 Objekt 4001 East Germany

On top of the bunkers some metal ventilation hatches appear to have resisted the demolition works. More interestingly, the metal cabin with the ladder for pedestrian access has been demolished, and access blocked with a concrete slab in both bunkers. In the southern bunker the concrete slab has been broken recently, and maybe a difficult access re-opened. However, this is not practicable if you are traveling alone – and is extremely dangerous in all other cases.

Abandoned Soviet Nuclear Warhead Bunker Lychen-2 Objekt 4001 East Germany

Getting there & moving around

Going to Lychen-2 is easy from the small nice town of Himmelpfort, about 1 hour driving north of downtown Berlin, in the heart of the natural preserve and nice tourist district of Oberhavel.

An access road is marked on the map attached to this post. You may see the Lychen-2 bunker from the satellite map, just north of the road, at the level of the launch platform for the SS-4 Sandal marked as ‘Furstenberg’. The latter post lists also several other Soviet-related destinations in the area, which may be more rewarding than Lychen-2. The (once) prominent secret Soviet base of Vogelsang (see this post) is also a highlight of the area, despite significant demolition works having taken place also recently, pushing also that part of the story towards oblivion.

The Border Forts of Czechoslovakia Against Nazi Germany

September 14, 2018September 28, 2019 CarloRLeave a comment

The Maginot line – a line of forts running along the French border with Italy, Switzerland, Germany and Belgium – is a widely known example of military engineering from the inter-war period (see this chapter). The adopted construction technique, based on reinforced concrete pillboxes with walls several feet thick, half interred to decrease visibility from above, field cannons and anti-tank defensive guns, witnesses the great consideration given to tanks and aircraft as attack weapons.

Due to the fast movements typical to the new strategy of the German army since the beginning of WWII, the Maginot line is mainly remembered for having not been involved in any major action, and having being largely bypassed. As a matter of fact, the German opted for a bypass also because the line was in place, so it was not as ineffective as it is often thought.

What is possibly even less known is that similar defensive lines were built in earnest in other European countries, before and even during WWII, after the Maginot line had failed to stop the invading German army. The enormous Salpa line, built by Finland against the Soviet Union, was probably the last and most effective to be completed (see this chapter). The Stalin line, prepared by the Soviets against Germany in Belarus, is another example. Another country who invested much in this type of deterrent was Czechoslovakia.

To understand the drivers of the design of the huge line of forts envisaged by the Czechoslovakian government of the mid-1930s, one should take a look at a map of Europe from the time. After the defeat of WWI Germany had managed to keep significant parts of todays Poland. The border between Germany and Poland ran close to Gdansk – aka Danzig in German -, and the province of Lower Silesia with the town of Wroclav – Breslau in German – were undisputed German territory. This means that todays border between the Czech Republic and Poland used to be actually a border between Czechoslovakia and Germany in the years before WWII.

With the turmoil preceding the infamous Munich Agreement and Nazi Germany claiming the right to control ‘Sudetenland’ – a large part of the peripheral territories of todays Czech Republic – in 1937 the Czechoslovakian government quickly started the construction of a huge system of forts to protect the border.

The concept was pretty similar to that of the Maginot line, with extensive underground tunnels to shelter soldiers and ammos, facing to the surface with reinforced concrete bunkers with different purposes, including observation, artillery shelling with field cannons, mutual protection with short range anti-tank cannons, machine guns and grenade-throwing tubes. There were also bunkers for accessing the tunnel system with resupply. About 10’000 light fortifications were actually built, more than 200 heavy fortified positions and a handful of heavy artillery positions.

The geopolitical situation in Europe got worse quickly in 1938, with the annexation of Austria in spring and finally the Munich Agreement, which caused the dissolution of Czechoslovakia. As a result of this internationally approved de facto German invasion, the works on the defense line were halted by the Wehrmacht. A relevant part of the hard construction had been completed, but most of the bunkers were still unarmed or lacked some software – air filters, ammo supplies, everyday items for the troops, etc. – and were not serviceable.

Most of the ironworks, including especially all heavy-metal turrets, were salvaged by the Germans. Some of the cannons found their way to the Atlantic Wall. The most massive concrete bunkers were used to test new weapons. As a result, the majority of the most sizable structures are still today in a partly damaged shape.

Some of the bunkers came to life again in the 1970s, when re-founded Czechoslovakia, that time a satellite country of the USSR living under a repressive and hard communist dictatorship, started a low-paced conversion of some of the structures into nuclear shelters for top ranks of the military and political hierarchies.

Notwithstanding these incidents, todays Czech Republic is duly proud of the significant work which was carried out in the difficult late Thirties. Very much was done for the little time available, and the quality of the design and construction is remarkable. While most of the sites are open only rarely, there are some where you can step inside and enjoy an interesting visit. This chapter covers with photographs and text five larger fortified complexes along this anti-German defensive line, from a two-days visit taken in August 2018.

Map

The following map shows the highlights of each of the five sites listed in this chapter. Please zoom in for greater detail. For the Bouda fort I could not spot and pinpoint on the map all the pillboxes you can easily visit from the outside – this are covered by vegetation.

Stachelberg

The Stachelberg site is located about three miles north of the small city of Trutnov. The fort should have consisted of a main entrance and peripheral shooting positions, some of them linked by underground tunnels, to defend the area of the Giant Mountains. Construction works were terminated much before completion, so the surface bunkers forming the ensemble are actually not connected. Yet the major installation, a bulky infantry positions with provision for anti-tank artillery, provides access to an extensive system of half-prepared tunnels, which gives you a clear picture of the size and capacity of the complex.

The site is open to the public, and the ticket office can be found right inside this huge major bunker. From the outside, the volume of this pillbox is particularly stunning. Also interesting are the anti-tank obstacles, which used to be placed along the border line and between the forts, to trap invading columns in a position where anti-tank guns could be most effective.

Stachelberg Fort Czech Republic

This multi-level bunker is also place for a little museum on the fortifications, mainly based on explicative panels and scaled models of weapons and of the entire bunker complex. It covers the history of the fortifications, and explains most technical features of their construction. There are no weapons or other software – they were either not installed before the construction works were stopped, or salvaged by the Germans.

The tunnels can be visited on a guided tour only, starting from inside the main bunker with a descent of several tens of feet along a flight of stairs, originally made at the time of construction. The tunnels unfold on the sides of a major, perfectly straight initial track. Some of the lateral halls, intended to store ammos as well as for sleeping the troops, are very large and close to completion, whereas others are just sketched.

Stachelberg Fort Czech Republic

The tunnels were dug in the rock with the help of explosives. The next step in the construction works would have been a layer of concrete from the pavement up to the ceiling of the tunnels. This is present today only close to the entry point, at the bottom of the access stairs.

Stachelberg Fort Czech Republic

There are at least other five smaller pillboxes which have been preserved to some extent in the Stachelberg complex. They are accessible with different timetables, and do not provide access to the underground – by design, some of them should have.

Stachelberg Fort Czech Republic

One of the pillboxes has been colored in a very bright camouflage. I could not find out whether this used to be the standard, but it looks pretty unusual and not really mimetic… There are also refurbished connecting trenches between the smaller bunkers.

The concrete base of a never built bunker can be found not far from the parking area.

Getting there and moving around

Getting close to the complex is really easy, the area is very scenic and a popular destination skiing, and for nature trail hiking in summer. There is a parking on road N.300 from where the museum-fort can be reached with an almost flat, 0.3 miles track.

The complex can be toured on the outside without restrictions. The main bunker has opening times, and the underground part can be toured only with a guide. The guide speaks Czech, but you are provided a leaflet with explanations in English, upon request. The tour takes about 30 minutes, and is offered on a regular basis, with several entries per day. They warn you about the inside temperature, but I found it pretty easy to bear with normal summer clothes. Website here, but you will need some Google translation to find the info you need.

Voda, Brezinka and Lom

These three forts are actually parts of the same system, built on the eastern end of the town of Nachod-Beloves, the major center in a local valley ending in Poland. Three items in the complex are typically accessible to the public.

The one closest to the town, on the bottom of the valley, is the Voda bunker. This is very convenient to reach, and is basically composed of a preserved typical infantry pillbox with provision for machine guns. The bunker has been painted in a credible camouflage. On one end it is possible to note the damage inflicted by the Germans, when they took out the metal observation turret. This kind of treatment – and damage – can be observed on a great many bunkers of the line.

Voda Brezinka Lom Fort Czech Republic

Inside, the bunker has been turned into a local museum on the armed forces. There were border guards operating in the area, involved in skirmishes before and after the end of the war. The weapons originally intended for the fort are not in place, but there is an interesting collection of weapons, uniforms, motorcycles and other gear from the army corps operating around there over the years.

Voda Brezinka Lom Fort Czech Republic

The Brezinka fort is possibly one of the most famous of the entire defensive line. The reason for that is that it was recently restored to look like it should have looked, if only it was completed back in the late Thirties. In the restoration process, weapons and system parts from other locations in todays Czech Republic were brought to the Brezinka site.

Voda Brezinka Lom Fort Czech Republic

The visit of the interiors is really exceptional, even compared to the forts of the other defensive lines in Europe. The fort really looks like it could be put in operation today!

The first part of the visit of this two-levels artillery bunker will take you downstairs, where you can find the sleeping quarters for the troops with a food storage.

Voda Brezinka Lom Fort Czech Republic

Close by, there are two rooms for the electrical generator and for the ventilation system. Here you can see the electrical compressor, with backup manual handles, and the huge air filters. These are multi-stage filters, where each stage was designed to stop different poisonous components in the air. The system is working, so you are given a demonstration of the compressor – interesting to get an impression of the incredible noise this system produced!

Voda Brezinka Lom Fort Czech Republic

On the same floor there is also a telegraph system, which was used to communicate with other bunkers in the complex in case of failure of the telephone link. This system was capable of transmitting Morse signals to the other pillboxes next to it, projecting the signal into the ground and using it as a medium – there were no cables! This allowed it to work even if a direct electrical link was lost.

Voda Brezinka Lom Fort Czech Republic

The upper floor is even more surprising, cause basically all weapons have been restored to their original positions. The Brezinka bunker featured two main firing chambers. The one pointing uphill features two heavy 7.92 mm machine guns Zbrojovka Brno Mark 1937, a very widespread and reliable weapon, with an operational range of 1’000-2’000 ft at 500-300 rounds per minute. These were used to target infantry movements along the border line, pinpointed by anti-tank obstacles. Fire direction was from the observation turret or via an optical aim system. The latter was extremely precise, but more expensive than the machine gun!

Voda Brezinka Lom Fort Czech Republic

In presence of an impenetrable smoke curtain or at night, an open-loop aiming system could be used. This consisted of a board with a precise sketch of the view of the outside from the firing point, mounted on top of the machine gun. A calibrated needle pointer was used to align the machine gun with respect to the target, by simply pointing the needle on the intended target on the board!

The third machine gun is a light ZB vz. 26, a very popular light 7.92 mm machine gun. This was used for close defense of the fort access. There are also grenade throwing tubes for the same purpose.

The other firing chamber points downhill, and is supplied with a machine gun as in the first chamber, plus the assembly of an anti-tank cannon and another machine gun. The cannon is a 4.7 cm Skoda KPUV vz. 38, with an up to 1-mile range at 35 rounds per minute. It could pierce a 50 mm armor from 0.7 miles apart, and was a very effective weapon. This very cannon was already in place before the German invasion, and was taken by the Wehrmacht to the Atlantic Wall in Norway. It has been returned to its original location in recent times.

Voda Brezinka Lom Fort Czech Republic

There are other two metal-reinforced embrasures in the bunker for other two ZB vz. 26s. On the same floor you can find a kitchenette and toilets for the troops, ammo storages, and two observation turrets. The latter feature a working movable floor, to allow tailoring to the height of the observer. The turrets were fitted with a periscope, and were used to direct fire. They weighed 21 tonnes each, and could withstand direct close fire from anti-tank guns!

Voda Brezinka Lom Fort Czech Republic

Finally, the room of the commander and the telephone room – with an original machine from the Thirties – conclude the tour.

Voda Brezinka Lom Fort Czech Republic

The Lom object, five minutes uphill with respect to the Brezinka fort, is another infantry bunker. It has not been refurbished to the level of Brezinka, but nonetheless it is used to showcase construction pieces, weapons and memorabilia from WWII years. The armored turret was taken away by the Germans.

Voda Brezinka Lom Fort Czech Republic

Between the Brezinka and Lom bunkers you can find a section of anti-tank obstacles. The concrete base used to support them can be spotted in several places here and other sites of the defensive line.

Voda Brezinka Lom Fort Czech Republic

Getting there and moving around

These bunkers, and especially Brezinka, are surely among the most interesting of the kind to visit, considering also their counterparts in France, Finland and Belarus.

The Voda site is easily accessible by car. The Brezinka and Lom bunkers cannot be reached by car. You can park on a street close to the trail-head and take the trail. Unfortunately, the road going uphill, albeit not uneven, is extremely steep and about 1 mile long. You should definitely take this into consideration when planning your excursion, even if you are physically well-trained. Very few beverages are available at the Lom site, which is five minutes farther uphill from Brezinka. Nothing is sold at Brezinka.

It is a pity they didn’t prepare a better access road, cause the site is surely worth a visit, and may appeal to the specialist and to the general public – especially children! – as well.

Only cash is accepted in all these sites. The Brezinka site is accessible only with guided tours. Tours were offered every 20 minutes in late August when I visited. You are given a detailed leaflet in English or German, in case you can’t speak Czech. The guided tour of Brezinka takes about 50 minutes.

The Lom site can be toured in 10 minutes, whereas the Voda bunker is worth a 20-30 minutes self-guided visit. Explanations are partly also in English and other languages in the Voda bunker.

Information on these three forts can be found from this website.

Hanicka

The Hanicka site features an extensive underground tunnel system, actually connecting the main entrance to some major peripheral forts. The ensemble includes one of the few most imposing firing units in the entire defensive line.

But what makes this site even more unique is the fact that, after having fallen into oblivion since the end of WWII, in the 1970s it was selected to be developed into a nuclear-proof governmental bunker – codenamed ‘Kahan’. The ensuing modifications altered greatly the appearance of the entrance bunker, and most of the systems you can see today in the underground part are actually dating from the 1980s.

The works on the conversion were carried out at a slow pace, and were actually not completed before the end of communism in Czechoslovakia, the collapse of the Czechoslovakian federation and the birth of the Czech Republic in the early 1990s. The bunker was soon opened to the public as a unique specimen of military building engineering from both WWII and the Cold War.

The tunnels can be be visited only with a guided tour. The original entrance to the tunnel, modified in the 1980s, is the starting point of the visit. The entrance to the bunker looked totally different before it was developed into a nuclear shelter. The modifications at the level of the entrance included the construction of a soft service building, with room for storages of trucks, armored vehicles and other material.

Hanicka Fort Czech Republic

In the first hall giving access to the tunnels you can find weapons, communication systems, scale models of the site, maps and much more from both the ‘two lives’ of the bunker, in the 1930s and 1980s.

Hanicka Fort Czech Republic

Access it through a thick, typical soviet nuclear-blast-proof gate. Inside, you see the nuclear-proof system allowed to seal a section of the entry tunnel close to the gate. The bunker was designed to allow long-term survival and operations for 300 people also in case of total insulation from the world outside.

Hanicka Fort Czech Republic

A modern energy production system was put in place and can be seen together with water and gasoline tanks. The structure of the bunkers was not altered significantly, but the various systems date clearly from more recently than the Thirties.

Hanicka Fort Czech Republic

There are also extensive sleeping quarters and a medical facility to the far end of the main tunnel, which was built in the side of a hill.

Hanicka Fort Czech Republic

You finally come out in a former infantry bunker, reached climbing upstairs to the top of the hill. Here the embrasures and reinforcing panels of the firing chambers are still in place.

Hanicka Fort Czech Republic

The next part of the visit will take you to some other smaller bunkers, visible only from the outside.

Hanicka Fort Czech Republic

The visit ends in front on the major RS-79a bunker, a top of the line artillery bunker. This was provided with three embrasures for field guns. The size of this installation is really striking. You cannot visit inside this bunker.

Hanicka Fort Czech Republic

It was somewhat damaged by weapons testing by the Germans, and never refurbished. You can see a nuclear-proof door substituting one of the original embrasures.

Back to the parking, it is possible to see from the outside an infantry bunker and examples of anti-tank barriers. This bunker is a rare example of a totally undamaged fort of the line – even the metal turrets are original and have been left in place by the Germans.

Hanicka Fort Czech Republic

Getting there and moving around

The Hanicka complex can be explored outside with no restrictions, but the inside can be toured only with a Czech-speaking guide. They provide you a leaflet in English. The visit lasts about 60 minutes. Info on their website.

The entrance is via the original entrance bunker, modified in the 1980s. Reaching this point from the parking on road N.319 is a bit demanding, cause you need to walk on an unpaved road going uphill with a relevant grade for about 0.7 miles, then you have about another 0.7 miles walking on an easy, flat road. Differently from Brezinka (see above), they have a facility selling food, beverages and souvenirs close to the entrance. It’s a pity they just did not prepare a good road and a parking nearby the entrance.

Anyway, this site has much to offer and the visit is highly recommended, both inside and outside, for children and adults as well.

Bouda

The two nearby forts of Bouda and Hurka share a basically similar construction, and represent possibly the best examples of almost-complete forts in the defensive line. They are articulated around a straight tunnel, mined in the side of a mountain. The section of the tunnel next to the main entrance bunker features a narrow gauge railway, used to transport ammos and various supplies to the storage units inside. Deeper in, there is provision for sleeping quarters for the troops. To the far end of the tunnel you can get access to a group of fortified installations and artillery bunkers.

The Bouda installation can be visited thoroughly. The site is very big but more remote to reach than Hurka. Besides the access bunker, where the ticket office can be found, you can see a specimen of a metal turret. None of the original turrets has been left in this site, all have been salvaged by the Germans.

Bouda Fort Czech Republic

Soon after the beginning of the tour, you will see the terminal of the narrow gauge railway. The double track goes through a short incline. At the base of the incline the main tunnel starts.

Bouda Fort Czech Republic

Not far from the entrance you meet slots for sealing doors and related actuation systems. These were installed by the Germans and used to test their reliability and the effectiveness of their weapons on them. They had some cannons installed further in along the tunnel, and shooting on the armored doors they had installed.

Bouda Fort Czech Republic

The railway turns single-track, until you reach a major storage for weapons with a loading platform. One of the storage chambers has been reused to display a collection of weapons used in the forts and the corresponding armored embrasures.

Bouda Fort Czech Republic

Further on you visit a group of chambers originally intended to be fitted as sleeping quarters. The dividing walls and metal frames have been demolished at some point – or may be they were never installed – but some of them can be seen, original or reconstructed. In this area there is also a memorial to Czechoslovakian troops.

Bouda Fort Czech Republic

Further in the tunnel you reach another set of chambers, one of them with pieces of armored constructions and other heavy material from around the site. Then you get access to the stairs leading to a heavy artillery bunker.

Bouda Fort Czech Republic

What you see here is the cylindrical concrete box where the actuation mechanism and reinforced cupola should have been installed. The size of the construction suggest the total intended size of the field cannon assembly, really big! This should have been very similar to some of the installations in the Maginot line (see this post). There is also a firing chamber for lighter weapons where nothing remains except some metal coating.

The guide will lead you back to the bottom and inside the main tunnel, and ascending along another stairwell you can reach an observation bunker with provision for light weapons. This bunker is in a better shape, and significant traces of the original soft construction are clearly visible.

Bouda Fort Czech Republic

Damage is due also to weapons testing carried out by the Germans, clearly visible from the outside.

Bouda Fort Czech Republic

Upon reaching the surface, you will be directed along a walk through the exteriors of the bunkers in the fortress, including the incomplete heavy artillery bunker, with the large concrete pit from visible above.

Finally, you access one of the bunkers, which appears pierced and heavily damaged from the outside. On the inside the firing chamber is fairly well conserved, with the original embrasures for machine guns still in place. The wall is pierced presumably by a shell or mine.

Bouda Fort Czech Republic

This very bunker was used also for testing high-yield explosives, and as a result of a huge explosion it shifted sideward of a few feet, without collapsing and with no alterations to its general shape – really sturdy! You can clearly appreciate the shift by going down in the stairwell!

You will then return to the main entrance with the ticket office where the visit will finish.

Getting there and moving around

The bunker parking can be found very easily driving north of the road N. 11 between Cervena Voda and Cerkovice. The area is popular for nature trail hiking, and the fort is also a popular attraction. Following the road signs, you will be driven to an observation tower on top of a mountain.

From there, the entrance to the bunker can be reached only by taking a trail which descends along the northwestern side of the mountain. The distance to cover by foot is a good 1.5 miles, so this should be taken into consideration when planning your trip. You have to go uphill on your way back to the parking, so the trail is more demanding when you are leaving. There are signs on every crossing, so you should not get lost. By the way, the walk is really nice, going in the trees with some bird-eye views on this beautiful countryside!

Once at the entrance of the bunker you can find refreshments and souvenirs. The bunker can be visited only with a guide. They are offering three options for the visit, each of them adding something to the other, yielding a difference in time. I took the most complete tour, and it took about 180 minutes.

You are provided jackets for staying inside – even though the temperature is not extremely low, especially if you are wearing technical trekking clothes, which are recommended for the preliminary trail to the entrance. The jackets are dirty, so it’s better to bring one of your own, as they almost force you to have something to cover in!

The tour is offered in Czech, with explanations in English provided on all panels and on a leaflet you can borrow inside. There is a fee for taking pictures, but both this and the entry ticket are rather cheap. Further info on their official website.

Hurka

The Hurka fortress is an installation pretty similar to the Bouda site, at least considering the inside part. After some years of closure following WWII, the Hurka site was converted into an ammunition depot in the 1960s. The modifications inside include some demolition work on the soft walls and frames, so the structure is mainly composed of large vaults.

The tunnels can be visited only with a guide. The visit starts from the original gate of the underground facility, where all supplies could be placed on a narrow-gauge convoy. An external loading platform can be spotted, together with specimens of anti-tank devices and of the reinforced observation turrets.

Hurka Fort Czech Republic

Inside, an incline leads to the initial part of a long straight tunnel. The exhibitions provide an impressions of an ammo storage, and there are also weapons and armored embrasures from the fort.

Hurka Fort Czech Republic

An interesting exhibition prepared in one of the halls is about the activities of the agents of the Czechoslovakian government in exile during WWII. This included launching paratroopers over the territory of the former Republic, tasked with establishing contact with dissident anti-Nazi movements, and carrying out high-risk, top-priority missions. A pretty famous mission they were tasked with was the assassination of Reinhard Heydrich, a top-ranking SS, since 1941 responsible for the administration of the annexed territory of todays Czech Republic. A bloodthirsty, feared and hated figure, he died in hospital soon after having being shot in June 1942 in an operation codenamed ‘Anthropoid’. All the spies involved in the operation were later killed, and terrible retaliation actions were taken by the Nazis on the local population. An international movie was produced on this subject in 2016.

Hurka Fort Czech Republic

You don’t get access to the firing positions from inside, but you can visit them from the outside on your own and with no restrictions.

A pretty rare feature is a ‘top of the line’ artillery bunker, with three shooting embrasures on one side. This bunker is today standing severely damaged from German fire, inflicted during weapon testing. The bunker was actually de-interred by the Nazis to expose its walls, and perforation cannons were tested on it. Among them, the so-called Röchling shells, with a high perforation potential, adopted operationally but used very rarely in action by the Germans.

Hurka Fort Czech Republic

The other artillery positions are scattered on a grassy area on the side of a hill dominating a local valley. You can see the damages inflicted by fire testing, and the empty boxes of the metal turrets salvaged by the Germans.

Hurka Fort Czech Republic

Getting there and moving around

The tour of the underground starts from the original access bunker, which can be reached just north of Kraliky on road N.312. Convenient parking outside. The underground can be accessed only with a guide. The ticked office offers also food and beverages. More info on their official website.

The firing positions can be toured on your own. They can be accessed driving about 0.3 miles north along the same N.312 road to the top of the hill, and turning left on an unpaved road. You will soon see a bar with a prohibition sign for cars. You can park nearby on the grass and proceed by foot, you will meet the fortification with an almost flat walk of 0.15 miles. There are signs with multi-language explanations close to each of the bunkers. The place is really nice, and the walk is highly recommended.

Inside the World’s Largest Aircraft – Antonov 225 Mriya

October 15, 2016May 9, 2020 CarloRLeave a comment

I am not sure this post does fit in the ‘sightseeing’ category. If you go to Malpensa – the largest airport of Milan – on a regular day, it’s unlikely you will spot the distinctive shape of the unique six-engined Antonov An-225. Yet in this post I will give a pictorial description of this crazy flying machine, so that wherever and when you should see the Mriya, here is what you might expect. This aircraft is a moving attraction, so exceptional that I feel going out to photograph it is still ‘sightseeing’ in some sense…

I had the chance to climb on it one night in early 2015, thanks to Paolo, a friend of mine from Italy, who is working in the company operating the airport system of Milan. The huge aircraft had been going in and out of Italy on an almost regular basis for some weeks, tasked with moving military equipment from central Africa back to the Italian soil.

It was a matter of coordination between me and Paolo, and of course some luck was involved, for the landing and take-off times of the Mriya are usually in the middle of the night and not perfectly predictable, plus good weather is never assured especially in winter. Anyway, in the end I succeeded in arranging a private visit to the Mriya with Paolo and another friend of mine. Paolo registered us as official visitors, so being there and allowed to walk on the apron of the largest airport in Northern Italy, we could come close also to some other interesting items.

The following photos are about that incredible night.

Sights

Mriya Parked

When we went on the apron the plane was still resting on its many (32) wheels, with doors closed and nobody around. The flight scheduled for that evening was basically a ferry flight to Africa, so no loading operations were expected. We were free to walk around taking pictures.

Antonov 225 Mriya

You may see how big this aircraft is by comparing its size to that of the guys walking under it. You will feel like walking close to a moored cruising ship more than an aircraft…

Air India Boeing 787 Dreamliner

While waiting for the crew to come to the aircraft for departure, we came close to a Dreamliner preparing for a flight to India. It still retained its ‘new plastic’ smell. Among the most distinctive features of this model are the beautiful engine nozzles, with a toothed profile for noise suppression.

Boeing 787 Dreamliner Air India

Emirates Airbus A380

We had the chance to see an A380 taxiing to the gate after arriving from Dubai. This double-decker is really impressive, as you can see again looking at the size of the people walking under its wings. Yet this time this was not the star of the show…

Airbus 380 Emirates

We walked up to the cabin, but were not allowed to take pictures. As it is the case for most modern aircraft, the cockpit is not so fascinating especially when the electronics are switched off – you just have an array of TV scopes…

Inside the Mriya

We then went back to the Mriya to meet the crew and walk in. The crew is composed by about ten people, including those connected with flight operations and those responsible for payload.

You get access to the aircraft through a hatch with an attached ladder. Otherwise, when the cargo door to the front is open, you may access the aircraft from there. There is no cargo door to the back.

Antonov 225 Mriya

The inside is structured with a main cargo deck in the central section of the aircraft, with a built-in crane capable of moving a 5 ton load. There are apparently no hooks on the ground, they possibly fasten the payload to the sides, but I’m not sure. The tail cone section can be accessed through an internal hatch for inspection, and cannot host any payload.

Antonov 225 Mriya

Along the sides of the cargo bay there are tons of bulky items and tools for servicing, spare parts including wheels, gauges connected with the landing gear operation, and small round windows to allow visually checking the wings and the engines underneath. The main cargo section is closed to the front by the folding platform for cargo loading, resting in a vertical position in flight, when the nose cargo door is closed and the nose cone lowered.

Antonov 225 Mriya

A retractable ladder gives access to the cockpit and crew resting area, which is configured in a similar fashion to the upper deck of the Boeing 747. To the front from the hatch on top of the ladder you get access to the seats of the flight engineers and to the cockpit. Seating in the engineering compartment is for four people, but I guess this was necessary for operating the Buran or for more complicate missions. Anyway, I would say at least a crewman for each side would be needed for normal flight operations. Seating in the cockpit is for two, and the arrangement of controls and gauges is neat and linear.

Antonov 225 Mriya

I would have spent one month in the engineering compartment to check every item in detail – tons of late Cold War items, and everything so Soviet-looking! – but this was not a day-off visit for the crewmen, who were busy with preparing the aircraft for the flight. To the back of the access hatch the quarters for the crew include two side compartments for living and sleeping, a small galley and a large storage room. From there it is possible to look through a window to another compartment to the back, with clusters of electronic material and other stuff, close to the wing section.

Antonov 225 Mriya

I noticed the usual placard with evacuation routes, and other strange knobs close to the upper-deck access ladder. Close to the side door of the aircraft the crew has many stickers from various places visited with this wonderful aircraft, and a bell like that of a 19th century ship!

Antonov 225 Mriya

Boeing 747 Cargo

Waiting for the Mriya to depart, we boarded a brand new Boeing 747 cargo of the Russian company ABC cargo. The contrast between this and the Antonov couldn’t be more striking. This new 747 has a fully automatic cargo deck, with a really impressive plethora of sensors and a system of rails to safely fasten cargo pallets. The flying deck is very comfortable and modern, with the typical brownish Boeing plastic, clearly reminding you this aircraft was ‘proudly manufactured in the USA’!

Boeing 747 Cargo ABC

Mriya Leaving

We finally went back to the Mriya to follow the departure sequence. The aircraft was pushed back with a dedicated towing strut, coping with the twin-mast front undercarriage. This item travels with the aircraft, so before engine startup it is necessary to open the front cargo door and load this gear, pushing it inside by pure handwork. The front undercarriage is tilted, lowering the front of the plane and making loading operations possible. After that, a crewman closes the side access door and startup of the six engines is initiated.

Antonov 225 Mriya

I shot a video during engine spool up, posted on my YouTube channel broadbandeagle.

Note

As I wrote at the beginning, this is a ‘special report’ and not a post with many how-to notes. I hope you got an idea of how the An-225 looks inside, but I was clearly lucky to be allowed on this special tour. All thanks go to Paolo, who invited me to join in, registering me as an official visitor. I dare to say that if you don’t know somebody doing his job and with his passion for aeronautics, then unfortunately you’ll hardly have a chance to board this aircraft and see the inside… unless you do his job yourself, or they retire the aircraft and put it in a museum!
