The events taking place on the geopolitical stage during the last decade of the Cold War – the 1980s – gave little indication of the imminent collapse of the Soviet-led Eastern Bloc (1989-1991). Correspondingly, looking at the amount of technology developed and deployed in the military field during the late, hi-tech stage of the Cold War, it is easy to notice that opponents on both sides of the Iron Curtain dedicated a significant (and even increasing) budget in preparation for a possible total confrontation. Reading papers and specialized books from the time, the outbreak of an open conflict, such to put a violent and abrupt end to years of opposition between the two opposing systems by recurring to nuclear warfare over the territories of Western Europe (most of them belonging to the NATO alliance, and all being substantially more militarized than today), was not deemed just likely, but more as a matter of time.

The БАРС system – The tropospheric network of the Warsaw Pact

In that era of extreme tension, it is not surprising that one of the most sophisticated and expensive assets developed and deployed jointly by all Nations in the Warsaw Pact, of course led by the USSR, came alive. History would cut its life short though, and as soon as the Warsaw Pact disintegrated, as a result of the opt-out from communist dictatorship of all Countries in Eastern Europe, this asset was decommissioned. This system was the tropospheric communication system ‘БАРС’, a Russian word reading ‘BARS’ and meaning ‘snow leopard’. The name stands as an acronym for four words in Russian, which translate into something like ‘Sheltered autonomous radio communication system’.

The idea put forward by the Soviet top-ranking military staff in the early 1980s (prior to the onset of Gorbachev administration) was that of a system capable of transmitting complex orders (not just simple signals, like for opening a bunker door or silo, but articulated messages) in a safe encrypted way, at a long distance and minimizing the chance of a complete breakdown even in case of an enemy nuclear attack. Despite being not new, the concept of a resilient and reliable system, such to allow exchanging significant amount of data without relying on cables, had been tested in earlier stages of the Cold War only for short-radius operations. Mobile transmitters/receivers, loaded on purpose-designed trucks, allowed for a reduction of the risk of a direct hit from an attacker, and for a quick redeployment in case of need. However, for the amount of data and range required for the coordination of a war scenario, involving many different Countries, and geographically encompassing an entire continent, a different system was required, capable of transmitting more massive data flows on longer distances, with a reduced risk of a sudden or complete interruption.

The БАРС system was based on a certain number of stations, scattered over the territory of the Countries of the Warsaw Pact. Each node was built as a bunkerized, manned military installation, featuring high-power, high-frequency fixed antennas emerging from the ground, and an underground shelter protecting all the technical gear required for manipulating the data to be sent or received, interfacing with the other existing local (i.e. national) networks for military and executive governmental communication, and of course managing the tremendous amount of energy required to pump a long-reaching signal into the ether.

Laying on the front line with the West, hosting a Soviet contingent of some hundred thousands troops (see here and links therein), aircraft (see here), missiles (see here) and nuclear warheads (see here), and being a key-ally of the USSR in case of the outbreak of an open war (at least until late 1989), the German Democratic Republic (or GDR, or DDR in German) was clearly included in the БАРС network from the initial drafting phase. Similarly, Poland, Czechoslovakia, Hungary and Bulgaria, and of course the Soviet Union (which included Belarus and the Baltics, and stretched west to Kaliningrad), all had БАРС stations on their territory. Stations were located at a range of a few hundred miles from one another, thus within the range required for each of them to communicate with one or more of the other nodes. Data (e.g. orders, reports or authorizations) input locally could be relayed along the network through intermediate nodes, down to the intended destination node. There were 26 nodes in total, of which four were in the USSR.

The Wollenberg site – Bunker 301 ‘Tushurka’

The GDR in particular had three stations built, all along the border with Poland, and located east of Berlin – namely Station 301 in Wollenberg, at the same latitude of Berlin, Station 302 in Langsdorf, towards the Baltic coast, and Station 303 in Röhrsdorf (near Königsbruck), not far from Dresden in the southeast of the GDR territory. The first among them, the Wollenberg site (codenamed ‘Tushurka’) could communicate with the other two national stations, as well as with Station 207 in Poland, from where data would be transmitted further down the network, towards the USSR.

The site was built by the GDR state, with technical hardware coming from several Countries within the Warsaw Pact, and most of the military hi-tech components manufactured in the USSR. The actual site (similar to its sister sites) was built in the frame of a highly secretive operation. The staff comprised about 60-70 men, the majority of which were military, where about 15% were civil technicians. Maximum security clearance was required, due to the top-secret nature of the installation and of the overall БАРС system. The bunkerized part of the installation was only a component of the larger premises of the base, camouflaged within the trees on the side of low-rising hill.

As pointed out, the immense spending required for setting up this multi-national hi-tech military communication system, which was extensively tested and completely commissioned (as a network) by 1987, did not save it from a quick demise and disappearance. In particular, Station 301 went definitively offline as early as August 1990.

However, the fate of the Wollenberg site was not so sad as that of many former Soviet or NVA (i.e. the East German Army) installations in the GDR. The high-power antennas were torn down, but except from that, little material damage was inflicted to the buildings and bunker on site. The place was basically shut-off and left dormant, until when a society of technically very competent local enthusiasts started a plan to preserve and open it to visitors, as a memorial specimen of the technology of the Cold War years.

A visit to the Wollenberg bunker site reveals a tremendous deal of interesting details, very uncommon to find elsewhere in the panorama of Cold War relics around Europe. Thanks to a careful preservation and restoration work, the bunker has most of its original systems still plugged to the grid and lit-up – some of them are reportedly still working! Even though the communication networks have been severed, the experience in the bunker is really evoking, and the atmosphere – with all the lit-up cabinets, lights, CCTV cameras, 1980-style screens, etc. – closely resembles that of the bygone era when БАРС was operative!

This report and photographs were taken during a private visit to the bunker, carried out in the Summer of 2023.

Sights

A visit to the the installation in Wollenberg starts from the original high-security access gate. As you may quickly notice when passing through it and getting a first view of the site, the state of preservation is exceptional. Except for the lack of military staff around, everything looks mostly like in the years of operation.

A group of soft-construction service buildings and a reinforced multi-entry garage constitute the first – and visible – nucleus of the installation. All buildings are painted in a camo coat.

A former building for the on-site staff has been turned into a permanent exhibition, with memorabilia items from the Cold War years, when the Nationale Volksarmee (or NVA, the Armed forces of the GDR) cooperated with the Soviet Red Army and the national Armed forces of other Countries in the Warsaw Pact.

A meeting room, now employed also for small gatherings, is especially rich of interesting and diverse items, including emblems, books, memorial plates and pennants, as well as TV screens, hi-fi systems and and beamers from the era.

Another room has been set-up as a control center for the base, with an original console and regional maps.

Compared to military bases (for aircraft or tanks), the Wollenberg installation is rather compact, with a main road giving access to most of the (not many) buildings on site, as well as the bunker. Actually, the bunkerized part was built under a low-rising hill, with the antennas originally standing on top of it. Access to the bunker is possible either by climbing uphill on the main road, or through a suggestive original pedestrian tunnel. The latter starts from within the service building itself, and – somewhat unexpectedly, for an underground installation – it climbs uphill, while keeping beneath the surface of the hill side slope. The lower end is guarded by an original CCTV camera.

At the top end of the tunnel you can find the actual access to the bunker. The design and reinforcement level conferred grade ‘D’ protection according to the military standard in use at the time, with grade ‘A’ being the strongest. Access is through an airlock, constituted by two tight doors at the opposite ends of a small vestibule built in concrete. This design allowed protection from the blast of a nuclear device.

Notably, the locking mechanism of the tight doors is Soviet military standard, which can be found in high-value installations like nuclear depots elsewhere in the Eastern Bloc (see for instance here in Poland, and here in Czechoslovakia).

To the visitor with some experience of Cold War installations, it will be apparent from the very start of the tour that the state of conservation of the bunker, including the systems in it, is exceptional, similar to the rest of the Wollenberg site. The original warning lights and the CC-TV camera for identifying people at the entrance are still in place.

Next to the entrance, a control room with technical gear for checking-in can be found – including original dosimeters for radiation and chemicals, mostly Soviet-made. Looking inside these devices is possible, and reveals a great deal of sophistication in the design and realization of the military-grade material from the time.

Showers and sinks for washing, as well as canister for disposing of contaminated clothes, are located in the same area.

Upon getting access to the sealed area of the bunker and passing by the decontamination facility, you find yourself on the top floor of the underground bunker. The high-technology gear required for the transmission/reception of data on the БАРС network, as well as the interface with other national communication systems, required for receiving data, issuing orders, etc. over the territory of the GDR, were located on this floor.

Two symmetrically placed rooms host two twin transmission centers for the БАРС system. A single manned console can be found in each of them, surrounded by electronic cabinets and switches. At a closer look, all the material herein is Soviet made, and labeled in Russian only.

On the wall ahead of the console station is a set of cables, communicating with the antenna and allowing to set the orientation and monitoring its status.

The actual signals transmitted to the antenna, or received from it, traveled along special hollow ducts, with an almost rectangular section. Bundles of these ducts can be found in the ‘Sender’ (which means ‘transmitter’ in English) room, immediately next to the room where the manned console is.

The modulation and demodulation of the signals going out and coming in respectively through the antenna on top of the bunker required some special pieces of electronics, which included the Soviet-designed KY-374 klystron (codenamed ‘Viola’), a component to be found in the cabinets of the ‘Sender’ room.

Following the hollow ducts, it is possible to find where they finally exit the usually manned part of the bunker, bending into receptacles and leading outside. Piping related to other systems, including air conditioning, can be seen as well crossing or running in the same narrow technical corridors.

Beside the consoles monitoring the antenna and the data flowing through it, a kind of operative room for communication can be found, where consoles allowing to receive and forward data and communication to/from all systems are on display. This largely original room features consoles of different levels of technology.

Original explanatory schemes showing the basic features of the БАРС system are on display in that area – in Russian!

An adjoining room features the cabinets required for making all these system work. The cabinets are really many, with a significant share of material manufactured in the USSR. The sight of all these cabinets together is really impressive, and tangibly provides the feeling of a high technology, sophisticated and expensive design. It compares well, but in a largely up-scaled fashion, to the electronics to be found in some special communication bunkers on the western side of the Iron Curtain (see here).

Interspersed with the original arrangement of the cabinets and consoles are some displays of original material. These include specimens of different types of cables for signal transmission – some of them hollow and pressurized, others featuring impressive bundles of thinner wires – the KY-374 klystron, and other once top-secret core components of the БАРС transmission system. Also on display is one of the few remaining parts of the original system of antennas, once on top of the bunker. The antennas were the only part to be physically torn down when the system was decommissioned, upon the demise of the Warsaw Pact and the end of the Cold War.

The bunker was manned by military and technical staff 24/7. Furthermore, as typical for bunkers from the Cold War era, provision was made at a design level to allow the staff to live isolated within the bunker for an extended period of time, in view of the eventuality to face a nuclear fallout scenario.

On the same floor as the technical rooms, the commander of the station had his own private room. This is still adorned with typical Soviet iconography, as well as everyday material from the age when the bunker was operative.

A small canteen, with a kitchen and a modest living room, can be found at the same level. An original storage room has been employed to gather examples of everyday products, like soap, skin care cream, etc., as well as canned food, cocoa, and beverages of all sorts.

This represents a very rich catalog of now largely defunct and forgotten labels, from the age and regions of the Eastern Bloc (and especially from within the GDR). Also on display are bottles of spirits, likely still very good!

The visit proceeds then to the lower floor, which can be reached through a flight of metal stairs.

The lower floor host the plants required for the regular operation of the entire bunker, such to guarantee operational ability even in case of an enemy attack carried out with nuclear, chemical or biological warfare. The air filtering and conditioning system is very modern. Beside typical filtering drums for particles, to be found also in other bunkers (see for instance Podborsko here), you can see a bulky filtering and climate conditioning system, neatly arranged within two parallel square-shaped ducts. Filtering against chemicals as well as biologic agents was carried out employing special active filters.

Sensors for the level of contamination of the bunker air can be found in different rooms. Much material here is standard Soviet-made.

Systems for water pumping and compressed air can be found as well, including compressors, pumps and reservoirs. Looking at the always interesting factory labels in this area, it is easy to find export products of Bulgaria, Romania and other communist dictatorships of the era. Of course, much hardware is also manufactured in the GDR.

Electricity was supplied from the outside grid, yet capability for self-sustaining in case of a grid loss (for instance in case of war) was implemented as well. Three big German-made Diesel generators have been put in place, and are still in an apparently good condition.

Another example of the high technological standard reached in the late Cold War era is represented by the control room for the plants within the bunker. A manned control station, with a console and a direct view of lit-up cabinets, reporting the status of the various systems running in the bunker, compares well with control rooms of large industrial plants in operation today.

Carefully kept in its original status, with many of the electric links and cabinets still working, the sight of this room is especially evoking.

Also on the lower floor are the sleeping rooms for off-duty staff. Typically, this was not employed except for drills, when the bunker could be sealed to simulate operations in case of the outbreak of hostilities.

Back to the upper floor, it is possible to exit the bunker via a stairway and through a side gate. You will find yourself on top of the low-rise hill where the bunker has been dug. Here the concrete base of the crane where the БАРС antenna used to sit are still visible. Notably, these antennas were much smaller than the tropospheric antennas employed for the TROPOSCATTER system of NATO. This was the result of a different bandwidth employed for transmissions. Therefore, even in the days of operation, the antennas on top of the bunker were not as sizable as those of TROPOSCATTER installations (which were enormous in size).

Looking closely, in the top area of the installation, the duct for supplying the Diesel oil tank of the bunker can be found, similar to sensors for radiation and other atmospheric parameters (similar to what can be found also in other nuclear-proof bases, for instance here). These allowed to monitor the conditions of the outside air, detect an attack and trigger or manage the sealing of the bunker in case of need, by locking all the tight doors.

This access to the bunker is fenced by the original electrified fence, severing this area from the rest of the installation through a further layer of security.

All in all, a visit to the Wollenberg bunker offers an incredible insight in a fascinating and crucial field of warfare – data and communication exchange – as well as a lively and evocative display of a late Cold War hi-tech installation from the Soviet side of the Iron Curtain!

Getting there & Visiting

The German name of the Wollenberg bunker is ‘Militärhistorisches Sonderobjekt 301 Wollenberg’. It can be reached very easily with a car. It can be found in the open countryside along the regional road 158, driving about 35 miles (about 1 hour) northeast from downtown Berlin towards Poland. The exact location is between the small village of Höhenland (~4 miles) and the more sizable Bad Freienwalde (~6 miles). There is a large parking area immediately next to the road, giving direct pedestrian access to the premises of the former military installation. Despite being placed very conveniently, the site is rather elusive when passing by, since it is hidden in the trees and not directly visible from the road. The address corresponding to the place in Google Maps is Sternkrug 4, 16259 Höhenland. The inconspicuous village of Wollenberg, giving the name to the installation, is just nearby, but it is not crossed by the regional road, and it should not be employed for pointing this destination with a nav.

The Wollenberg bunker is a listed historical installation. It is perfectly maintained, privately managed, and it can be regularly accessed with guided tours. These are offered typically one day per week in the summer, or by prior arrangement. Possibly the best option for getting the most out of your visit is getting in contact with the group of very knowledgeable enthusiasts running the place. The official website is here (do not be discouraged by the ‘static’ appearance of the website, they are very active, and they shall typically answer your inquire).

My visit was planned by initiative of Dr. Reiner Helling (see also here), and we visited in a group of three, including the guide (Dr. Michael Schoeneck, a former engineer, with a profound knowledge of any technical aspects related to this installation), which happened to be a perfect option for touring also the narrowest receptacles of the bunker. Visiting in groups too big may be not advisable, since the rooms and corridors are rather narrow, and the place may turn overcrowded for interacting with the guide and for taking good pictures. I think the visit – including the technical content – may be tailored to the needs of the audience. For technical-minded subjects, historians and former military, a visit may take about 2-3 hours (the latter was my experience). In my case, the guide could understand but not speak fluent English, yet Dr. Helling could translate with ease all the explanations. Of course, if you have at least a basic knowledge of German and of the technical material you are looking at, this may simplify your visit, which is in any case highly advisable for those interested in military technology and the Cold War.

Herdla Torpedo Battery – Defending Bergen in WWII and the Cold War

Despite overshadowed by the natural beauties of Norway, the heritage of the rich war history of this Country would really deserve a dedicated trip. Thanks to its geographical location, this Scandinavian Nation had a primary strategic role both in WWII and the Cold War.

Hitler’s Third Reich military forces conquered Norway early in WWII (Spring 1940), gaining an effective stronghold for launching sea and air patrolling missions over the Norwegian Sea and the northern Atlantic. The long coastline stretching from the Skagerrak strait up to North Cape was made impenetrable to enemy invasion, building anew a capillary network of fortifications – the Atlantic Wall. This masterpiece of military engineering was based on an extensive catalog of reinforced concrete standard elements (Regelbau in German), ranging from fortified casemates to radar towers, to observation and target range finding stations, to bunkerized gun batteries, etc. These elements were assembled in larger fortified compounds, placed in key strategic locations along the coast or in the narrow firths reaching to major ports and towns, like Bergen or Trondheim.

Typically run by the Kriegsmarine (Navy) or Luftwaffe (Air Force), these forts may comprise measuring stations, anti-shipping guns, anti-aircraft cannons, plus barracks, services, ammo storages, and even airfields in some cases. They were built not only in Norway, but having been originally planned by the Third Reich to protect the entire coast of conquered continental Europe, they were erected along the shoreline also from Denmark down to France.

As a matter of fact, many of the Norwegian fortresses of the Atlantic Wall rank today among the most massive and well-preserved of the entire line (see here for some highlights).

But the war history of Norway, and of its mighty military infrastructure, didn’t stop with the end of WWII. With the start of the Cold War, Norway became a NATO founding member, and once again of great strategic value. It found itself in close proximity to the USSR, and with a long coastline facing the sea corridor taking from the highly-militarized Murmansk and Kola Peninsula (see here) to the northern Atlantic.

Most of the Atlantic Wall forts, especially anti-shipping and anti-aircraft gun batteries, were obsolete by the 1950s, and were soon deactivated. Some were abandoned or, when retained by the Norwegian military, they were modified to cover new functions.

In a few cases, the original mission of the site by the Third Reich was retained by NATO forces in the Cold War. This is the case of the torpedo battery in Herdla.

The fortress of Herdla was a major strategic fort in the Atlantic Wall, allowing to keep a watch on the entry point to the inner waters leading to the large industrial and military port of Bergen. Thanks to the morphology of the area, featuring a rare spot of flat land nearby a steep and rocky cliff, an airfield was installed by the Third Reich besides a set of bunkers, effectively hidden in the rocks. A land-based torpedo battery, consisting of a range-finding and aiming station and torpedo-firing tubes, was part of the fort.

During the Cold War, it was decided that the torpedo battery could be still a valuable asset, and Herdla was retained by the Norwegian military – by comparison, the airfield, too short for the requirements of the jet-era, was not. Over the years, the torpedo battery was potentiated to keep up-to-date against the technological offensive capabilities of the Eastern Bloc, and to exploit the most modern identification and surveillance techniques.

The torpedo battery was part of a larger naval fort, which controlled also the barrier of sea mines implemented to stop a sea-based intrusion towards Bergen.

As a matter of fact, the area control functions and the offensive capability of Herdla were retained until the early-2000s, when the fortress was deactivated following the end of the Cold War and defense budget cuts.

Luckily however, the often neglected Cold War chapter of warfare history has in Herdla a valuable asset – an accurately preserved fortress regularly open for a visit. A modern visitor center welcomes the more curious travelers, leaving Bergen towards the remoteness of the coast. It retraces the WWII heritage of the Herdla site, thanks to an exhibition centered around an original Focke-Wulf FW190, recently salvaged from the bottom of the sea, and with a special history to tell. Then a visit to the battery, looking like it had just been left by the military staff, is a unique emotion for both the specialized war technology enthusiasts and the general public as well.

The following report and photos is from a visit taken in Summer 2022.

Sights

As outlined in the overview, the Herdla site today is centered on two major highlights. One is the visitor center, with the preserved relic of a unique Luftwaffe Focke-Wulf FW190. The other is the former torpedo battery and Navy area command bunker, Norwegian facilities installed during the Cold War in bunkers dating to the Third Reich era.

Visitor center & Focke-Wulf FW190 exhibition

The relic of a Focke-Wulf FW190 A-3 German fighter from WWII is hosted in a dedicated room, where a scenic lighting makes this impressive exhibit literally shine.

This exemplar of the iconic Third Reich fighter, produced in some thousands examples, and now almost impossible to find especially in Europe, is ‘Gelbe 16’ (which can be translated in ‘Yellow 16’) of 12./JG5, and its history is deeply related to Herdla.

It took off on December 15th, 1943, from the airfield the Luftwaffe had established on the flat area now lying ahead of the visitor center, at the time a very active German airbase.

Following troubles with the engine, it ditched in the cold inner water near the island of Misje, some ten miles south of Herdla, the pilot being able to abandon the doomed aircraft, and being saved by local fishermen – and returned to the Luftwaffe, who had a Norwegian resistance prisoner released in acknowledgment.

The aircraft sank to the bottom of the sea, but its memory was not lost by some of the locals, who clearly remembered the events. The Focke-Wulf remained there for 63 years, but it was finally located and pinpointed by the Norwegian Navy, instigated by local interest, in 2005. After preparatory work – including exploration dives, to assess the condition and to set-up recovery operations – the fairly well-preserved wreck was lifted to the surface on November 1st, 2006, and loaded on a tug. Conservative restoration work then took place in Bergen.

Instrumentation and the machine guns were all recovered, together with many further fragments of equipment. Interestingly, evidence of repaint was found during conservation, retracing some previous assignments. Yet the history of this very exemplar remains difficult to write in its entirety.

Finally, following completion of conservation works, a new home for the aircraft was prepared in Herdla, where a hangar was built anew – and this is where you can see it today.

The aircraft is in an exceptional state of conservation, considering it spent 63 years in sea water. The fuselage, wings and tail are not significantly damaged, with just some paneling having disappeared on tail control surfaces, due to corrosion. The swastika on the vertical stabilizer is still perfectly evident, like other painted details.

The propeller blades are all bent downstream, as typical for an emergency landing carried out without the landing gear and the engine still running. The tail wheel is there with its original tire, the emblem of the German brand ‘Continental’, still in business today, being clearly noticeable.

The instrumentation from the pilot’s control panel has been put on display separately. Also a gyroscope has been found. Everything is only slightly damaged. Similarly, the two machine guns, dismounted prior to lifting the aircraft from the sea, are little damaged, and displayed with some ammo.

Complementing the exhibition are a few other pieces from other wrecks, as well as some quality scale models and dioramas portraying Herdla in the days of Third Reich tenancy.

Torpedo Battery

Access to the torpedo battery, which was built in WWII just above sea level, is from a gate on the land side. From outside, the bunkers in the fortress of Herdla appear especially well-deceived in the rocks of the cliff.

What is seen today inside, however, dates to the years of Norwegian tenancy. The facility was updated in several instances during the Cold War, the last in the 1990s. Immediately past the gate, you get access to a modern and neat mechanics shop, where a partly dismounted torpedo allows to have a suggestive look inside this marvelous weapon.

Interestingly, Norway inherited and went on operating a significant number of German G7a (TI) torpedoes. This was the standard torpedo employed by the Kriegsmarine since 1934, and with some modifications (‘TI’ standing for ‘first variant’, the later variants bearing other codes), for the full span of WWII.

Propulsion power for this torpedo was from a piston engine, fed by high-pressure vapor obtained by the combustion of Decaline with compressed air stored onboard, mixed in a heater (i.e. a combustion chamber) with fresh water, similarly stored in a tank. The resulting mixture fed a 4-cylinder radial piston engine, driving two counter-rotating propellers. The exhaust in the water produced a distinctive contrail of bubbles, and the presence of a high-frequency moving mechanism had the side-effect of a significant noise emission. The head of the cylinders can be clearly seen in the dismounted exemplar.

Guidance was provided by rudder steering controlled with the help of gyros, whereas depth was controlled via a mechanical depth sensor. The torpedo could stay close to the surface or keep an assigned depth. In WWII the torpedo had no homing device – i.e. it was ‘blind’, thus requiring carefully putting it on a target-intercept trajectory. It could however cover pre-determined trajectories of some sophistication. The set-point selection for guidance and the yaw regulation gyro assembly have been taken out of the torpedo, and can be checked out in detail.

The range could be selected before launching, and was traded off with speed. It could be between 5.500 and 13.200 yards, and the speed ranged between 44 kn and 30 kn correspondingly. The German origin of the torpedo on display is betrayed by the writings in German on some parts.

Leaving the workshop through a gate towards the inner part of the bunker, a roomy supply storage area can be found, with some interesting material including torpedo parts, as well as a torpedo launching cannon.

This item represents the primary way of launching torpedoes in the early Cold War from land-based batteries or ship decks. This was a technology inherited from WWII, when coastal batteries of the Atlantic Wall ejected torpedoes from slots in the bunker wall, shortly above the surface of the water, employing cannons similar to this one (which dates from the Cold War period), thanks to a burst of compressed air. This cheaper, but less ‘stealthy’ and accurate launching procedure, was replaced by underwater launching tubes only over the years of the Cold War, featuring an increase in the level of sophistication of warfare. Correspondingly, the slots in the side of the torpedo battery bunker facing the water were bricked up, and torpedo cannons were retained mostly for use from the deck of warships.

From the storage room you get access to the core area of the battery. This is through a decontamination lock, with gear for anti-contamination testing, including paper strips for checking contamination from poisonous gas.

The battery features two diesel generators for electric power, employed in case of disconnection from the regional grid.

Less usual – for a military facility – is the presence of two air compressors. Compressed air is relevant for torpedo operation, being employed for the launch burst from the torpedo tube, as well as for propulsion and gyros in the G7a torpedo. The air compressors in Herdla are made by Junkers, solid German technology from 1961!

A few bunkerized resting rooms for the staff manning the battery can be found in the same area, besides the power/compressed air supply room and the torpedo room. The resting rooms are minimal as usual, with suspended berths, and much personal military equipment on display – coats, blankets, medical kits, and more technical material.

Finally, the core of the battery is the torpedo room. This is much longer than wider, access is via the short side. In the Third Reich years, the launching slot was on the short side to the opposite end of the room, right above the water. Today, this slot has been bricked up, and there is no window at all.

The torpedoes are aligned on racks along the long sides of the room. The launching system is via two underwater tubes, which are accessed via obliquely mounted hatches, one to each side of the room at the level of the floor. The section of the racks closer to the entrance door is actually a pivoting slide. The slide could be pitched down, thus allowing the torpedo to slip through the hatch in the firing tube. The original launch control console can be found to the right of the access door – in a mint condition, it looks really like it had just been put in standby following a drill!

Over the years, the stockpile of G7a TI torpedoes was upgraded especially in terms of guidance. The major modification was the adoption of wired control. This is based on a thin electric cable unwinding as the torpedo proceeds along its trajectory, keeping it linked with the launching battery. This upgraded model is called G7a TI mod 1. Control via a steering joystick and trajectory monitoring system could provide manual guidance to the torpedo, thus sharply increasing the chance of target interception. This technology is still in use today. Wire tubes can be found on top of the rudder of torpedoes.

Besides the G7a, Herdla battery received the TP613 torpedo, a weapon developed in Sweden in the early 1980s from previous designs. Exemplars of this torpedo, still in use, are visible in the torpedo room. In terms of mechanics, the piston engine of this torpedo is powered by the reaction of alcohol and Hydrogen-peroxide. In terms of guidance, this torpedo features improved wired communication for guidance and power setting (i.e. changing torpedo speed during the run), as well as passive sonar homing. A dismounted section exposing the engine can be found on display.

The wire tube installation on top of the rudder is featured also on this model, and examples of the wire are on display.

The original guidance console, made by Decca, with a prominent joystick on it, is on display as well!

Training and proficiency checks are typically carried out without a warhead, but with an instructional head. Distinctively painted in shocking red, and with powerful lights in them – to show their position to simulated targets during training exercises, when needed – these are on display in a number. Since the torpedoes, just like missiles, are very expensive, a way of recovering them after instructional use has been envisioned, in the form of inflating bags coming out of the head, increasing the buoyancy of the emptied torpedo and forcing it to surface when reactants tanks are empty and power is off.

Offensive warheads can be exchanged with dummy ones for training, bolting them to the body of the torpedo, which remains totally unchanged. A warhead with a 600 lbs explosive load, triggered by a proximity pistol, was typically put on G7a torpedoes. The proximity pistol was made of four petals, which on contact with the target were bent towards a conductive metal ring around the nose cone of the torpedo, closing an electric circuit and triggering the explosion.

Leaving the torpedo room and the bunker is via the same way you came in.

Sea Mines & Area Control Center

But your visit is not over. As mentioned, the Herdla coastal battery hosts an area control center, with provision to manage target detection facilities and the minefields in the waters around Bergen.

This part was built in a facility strongly potentiated with tight doors, typical to the shockwave-proof military construction syllabus of the Cold War. A sequence of roomy vaults carved in the rock hides a number of containerized modules, together with an exhibition of sea mines and related apparatus.

Most notably, an L-type Mk 2 moored mine and a Mk 51 bottom mine are on display, with a understated control panel. The latter is actually a portable controller for triggering the mines. Already before WWII, sea mines were often put on the bottom of the sea in shallow waters, or moored in deeper waters, to control access inner waters, firths, ports, etc. The Germans made extensive use of this technique in Norway, and following WWII this strategy was inherited by Norway to protect its waters from (primarily) Soviet intrusion.

Despite contact mines were still popular in WWII, they have been surpassed and gradually replaced already in that age by proximity mines, based on noise and – especially – magnetic sensors. Today, proximity fuses activated by the magnetic field of ships or submarines passing nearby are standard technology. Onboard electronics allows to distinguish between the magnetic signature (i.e. fingerprint) of different ships, thus avoiding any issue for civilian or friendly traffic, and activating only against enemy shipping. Degaussing techniques – i.e. the ability of military ships to hide their signature – have forced to improve detection technology, which is today extremely sophisticated.

Furthermore, for the protection of ports and friendly waters, sea mines are typically controlled and triggered by hand, upon detection and localization of enemy shipping, by means of dedicated detection facilities on land or water. This improves precision and allows more flexible defensive-offensive tactics, since a human chain of command has control on the minefield, instead of a pre-determined computer program.

To trigger the mines, consoles like that on display are employed, where a trigger for each mine allows precise control over the minefield.

The first containerized control center hosts a similar, yet much more modern, dedicated console. Everything in this movable control center is very neat, and really looking like reactivation might take place in just moments! Of interest is also the situation map, covering the area around Herdla and the water inlet to Bergen.

A nearby container reveals berths and a small living area for stationing staff.

Yet another container hosts a complete situation room covering the area. Similar to the coastal battery in Stevnsfort, Denmark (see here), a careful eye was constantly overlooking the shipping in the area.

In the same container, a console for steering torpedoes, more modern than that previously seen in the torpedo battery, is on display.

All in all, Herdla is a one-of-a-kind destination, of primary interest for those interested in Cold War military history, enjoyable and easy to visit. Totally recommended for everybody with an interest in history, with much to see and learn for the kids as well.

Getting there & Visiting

Herdla fortress features an official visitor center with a large parking area, and amenities including a small restaurant and a shop. The official website is here. It can be reached about 27 miles north of central Bergen, roughly 45 minutes by car. The address is Herdla Museum, Herdla Fort, 5315 Herdla.

The torpedo battery and control bunker can be visited only on a guided tour. Visiting from abroad, we scheduled an appointment, and were shown around by the very knowledgeable guide Lars Ågren, a retired officer of the Royal Norwegian Navy. He joined the Navy in the late 1970s, in time to gain a substantial, hands-on Cold War experience during the final, high-tech part of that confrontation. He was promoted to tasks in the NATO headquarters in Belgium, later returning to Norway, and totaling more than 37 years in service. He is strongly involved in the management of the Herdla site. Chance is for you to embark on a visit with this guide, or other very competent guides who will satisfy the appetites of more committed war technicians and engineers, being capable of entertaining also the younger public as well.

A visit to the torpedo battery and control center may last about 1 hour. Seasonal changes to opening times may apply, as common in Northern Countries, therefore carefully check the website.

Soviet Nuclear Bunkers in the Czech Republic

History – In brief

After the end of WWII and the collapse of the Third Reich, the territory now belonging to the Czech Republic fell on the Soviet side of the Iron Curtain. Together with today’s Slovakia, it formed the now disappeared unitary state of Czechoslovakia. Despite laying right on the border with the West – including Bavaria, which was part of West Germany and NATO – communist Czechoslovakia enjoyed a relative autonomy from the USSR, until the announced liberally-oriented reforms of the local communist leader Dubcek in the spring of 1968 triggered a violent reaction by the Soviet leader of the time, Leonid Brezhnev (see here). About 250’000 troops from the Warsaw Pact, including the USSR, landed in the Country. As a result, the Soviets established a more hardcore and USSR-compliant local communist regime, and largely increased their military presence.

Similar to the German Democratic Republic (see here for instance), Hungary (see here) or Poland (see here), since then also in Czechoslovakia the local national Army was flanked by a significant contingent of Soviet troops, who left only after the entire Soviet-fueled communist empire started to crumble, at the beginning of the 1990s.

Consequently, for the last two decades of the Cold War, Czechoslovakia was a highly militarized country similar to other ones in the Warsaw Pact (see here). Its geographical position on the border with the West meant it received supply for a high-technology anti-aircraft barrier (see here). Two major airbases in Czechoslovakia were taken over for use by the Soviets and strongly potentiated (see here).

Soviet Nuclear Depots in Czechoslovakia

Beside conventional forces, also nuclear warheads were part of the arsenal deployed in this Country. Where in the late 1960s Soviet strategic nuclear forces were already mostly based on submarine-launched missiles and ICBMs ground-launched from within the USSR’s borders, tactical forces were forward-deployed to satellite countries, to be readily operative in case of war in Europe. Missile systems like the SCUD, Luna (NATO: Frog) and Tochka (NATO: Scarab) were deployed to the Warsaw Pact, supplying either the local Armies or the Soviet forces on site. Typically armed with conventional warheads, these systems were compatible with nuclear warheads too, making them more versatile, and of great use in case of a war against NATO forces in central and western Europe (see here).

Irrespective of their employment by a local national Army or a Soviet missile force, nuclear warheads were kept separated from the rest of the missile system for security, and invariably under strict and exclusive Soviet control. Bunker sites were purpose built in all components of the Warsaw Pact for storing nuclear warheads – see page 46 of this CIA document, showing with some accuracy the location of the corresponding bases.

Granit– and Basalt-type bunkers were typically prepared on airfields or artillery bases, for short-term storage of soon-to-be-launched nuclear weapons. Instead, top-security Monolith-type bunkers (the triangles on the map in the CIA document) were intended for long-term storage of nuclear ordnance.

Monolith-type bunkers were built by local companies on a standard design in the Soviet military inventory, and were implemented in satellite Countries in the late 1960s. Czechoslovakia received three such sites, which took the names Javor 50, by the town of Bílina, Javor 51, close to Míšov, and Javor 52, close to the town of Bělá pod Bezdězem. All three locations are in the north-western regions of today’s Czech Republic.

The Soviet military started withdrawing the nuclear warheads from satellite Countries in 1989, months before the collapse of the wall in Berlin. As for Czechoslovakia, by 1990 all nuclear forces had been moved back to the USSR. Following the end of the Cold War, Monolith-bunkers – similar to most of the colossal inventory of forward-deployed military installations formerly set up by the Soviet Union – were declared surplus by the Countries where they had been implemented.

These primary relics of the Cold War have known since then different destinies. Some of them have been hastily demolished, and together with their associated fragments of recent history, they have almost completely disappeared into oblivion. Luckily, a few are currently still in private hands, and still in existence (see here and here) – specimens of recent military technology, and a vivid memento from recent history, when the map of Europe looked very different from now. Two can be visited, of which one is Javor 51, in the Czech Republic, the main topic of this post. This has been turned into the ‘Atom Museum’, which has the distinction of being the only Monolith-type site in the world offering visits on a regular schedule (the other open site is Podborsko, in Poland, covered here, which is open by appointment).

Also displayed in the following are some pictures of the now inaccessible site Javor 52 in former Czechoslovakia. Photographs were taken in 2020 (Javor 52) and 2022 (Javor 51).

Sights

Javor 51 – The Atom Museum, Míšov

An exceptionally well preserved and high-profile witness of the Cold War, the nuclear depot Javor 51 is a good example of a Monolith-type installation. These bases were centered around two identical semi-interred bunkers for nuclear warheads.

When starting a visit, you will soon make your way to the unloading platform of bunker Nr.1. The shape of the metal canopy, and the small control booth with glass windows overlooking the platform are pretty unique to this site. The metal wall fencing the unloading area is still in its camo coat outside, and greenish paint inside. Caution writings in Russian are still clearly visible. Concrete slabs clearly bear the date of manufacture – 1968. This site was reportedly activated on the 26th of December, 1968.

Even the lamps look original. Some of the – likely – tons of material left by the Soviets on the premises of this site has been put on display ahead of the massive bunker door.

The opening mechanism of the latter is a nice work of mechanics. Four plugs actually lock or unlock the door. They can be moved by means of a manual crank, or likely in the past via an electric mechanism (some wiring is still visible). The thickness of the doors is really impressive (look for the cap of my wide lens on the ground in a picture below for comparison!).

Each bunker had two ground-level entrances to the opposite ends, each with two blast-proof doors in a sequence. Warheads were transported by truck, unloaded beside the entrance of one of the two bunkers, and carried inside through the two doors, which constituted an air-tight airlock.

Today, you can see the inside main hall of the bunkers from the outside during a visit. This was likely not the case in the days of operation. The opening procedure required a request signal to travel all the way to Moscow, and a trigger signal traveling in the opposite direction. Once past the first (external) door with the warhead trolley, that door was shut, and the procedure was repeated for the second door, giving access to the inside of the bunker.

A security trigger told Moscow when the door was open. It can still be seen hanging from top of the door frame.

Once inside, you find yourself on a suspended concrete platform. The warhead trolley had to be lowered via a crane – still in place – to the bottom of the cellar ahead, i.e. to the underground level. The stairs now greatly facilitating visitor’s motion around the bunker were not in place back then, and descending to the underground level for the technicians was via a hatch in the floor of the suspended platform, and a ladder close to the side wall.

On the platform, an original Soviet-made air conditioning system can be seen – with original labeling – and signs in Russian are on display on the walls.

The platform is also a vantage point to see the extensive array of heat-exchangers put along a sidewall of the central hall – atmosphere control was of primary importance for the relatively delicate nuclear warheads. Each of them traveled and was kept in a pressurized canister. However, also the storage site was under careful atmospheric control.

To the opposite end of the bunker, the inner tight door of the second entrance can be clearly seen, ahead of another suspended platform. The warheads left the bunker for maintenance (they might have left also for use, but this never happened, except possibly on drills) from that entrance, which had a loading platform outside for putting the warheads on trucks (this can be better seen in other Monolith sites, like Urkut in Hungary, or Stolzenhain in Germany).

Down on the lower level, the main bunker hall gives access to one side to four big cellars, where the warheads spent their time in storage, and to the other sides to technical rooms. The pavement in the storage cellars features the original metal strongpoints, used to anchor the trolleys for the warheads to the ground. This was in case of a shockwave investing the site in an attack, to avoid the trolleys moving and crashing against one another. The original hooks with spherical joints to link the trolley to the strongpoints are also on display.

The storage cellars today have been used to display informative panels, with many interesting pictures and schemes. These include some from major sites connected with the history of nuclear weaponry in the Soviet Union (like from the test site of Semipalatinsk) and the US (like the Titan Museum near Tucson, AZ, covered in this post).

A few former technical rooms are used to store much original technical gear. This ranges from spare parts, tools and personal gear like working suits left by the Soviets (most with signs in Russian), to items ‘Made in Czechoslovakia’ or even radiation detectors from Britain and the West, gathered here for display and comparison.

Some of these spare parts are wrapped and sealed in Russian, looking like they were cataloged back in the time of operations.

In the main hall, many rare vintage pictures retrace the presence of Soviet military forces on this site as well as others in Czechoslovakia. Magnified copies of rare pictures portray the trucks, canisters and the very warheads likely involved in transport and storage in Javor 51. Actually, much mystery exists around the deployment of nuclear ordnance by the USSR outside its borders (not only to Czechoslovakia). Historical and technical information today made available, even to a dedicated public, is very limited, making this chapter of Cold War history even more intriguing.

Again in the central hall, cabinets for monitoring the nuclear warheads can be seen hanging from the walls, painted in blue. Each warhead used to be stored in a canister, which was periodically linked to these cabinets to check the inner atmosphere, temperature, etc., in order to monitor the health of its very sensitive content.

A large part of the technical/living rooms has been preserved in its original appearance. You can see parts of an air conditioning system, a big water tank, a toilet, a now empty bedroom for the troops. The bunker was constantly manned inside by typically six people, who operated in shifts. They did not sleep there, nor used the toilet much due to poor drainage. However, these facilities were used in drills, and were intended for the case of real war operations, when the bunker might have been sealed from the outside.

The electric cabinets take a dedicated room, like the huge air filters and pumps (Soviet made), installed to grant survival of the people inside the bunker in case of an attack with nuclear weapons or other special warfare. Clearly, the level of safety in the design of the bunker stemmed from the fact that it was considered by the Soviet as a a strategic target for NATO forces.

The last technical rooms host a big Diesel generator, supplied with air from the outside, and a big fuel tank in an adjoining room. Many labels bear writings in Russian, but the generator appears to be made in Czechoslovakia. The bunker was linked to the usual electric power grid of the region, and the generator was intended for emergency operations, in case the grid was lost or the bunker was isolated.

From the technical area, it was possible to access or exit the bunker, via a human-size airlock. The innermost tight door can be seen painted in yellow, with a locking mechanism resembling that of the major tight doors for the missile warheads. Outside the airlock, climbing three levels of ladders was required to get to the surface. This was the normal access to the bunker for the military technical staff, except when warheads arrived or left the storage (this was made via the major entrances, as explained).

Back outside, the second bunker, Nr.2, can be found at a short distance from the former. Nr.2 is being prepared for an exhibition on technology. At the time of writing, it can be toured except for the technical/living rooms. It is in a very good condition, and allows to get similar details as the previous Nr.1 on the construction of this type of facility – including the heating/air conditioning system.

The blue cabinets for plugging the canister for routine status checking and maintenance can be found also in Nr.2 in good shape.

Clearly visible here are the doors closing the technical areas and the warhead cellars. The latter were monitored for security just like the external airtight doors of the bunker, each with a sensor telling controllers whether the cellar was locked or not.

The airlock is covered in soot, possibly the result of a fire. Ahead of the entrance, the unloading platform is very interesting, having a unique set of light doors which had to be opened to allow trucks to come in. The concrete part of the platform appears slightly off-standard, with a short lateral concrete ramp, giving access to the main platform from one side. Parts of missiles – original – are being gathered in this area for display.

Monolith sites include two bunkers, which are the core of a strongly defended fenced area. In Javor 51, fences except the external one have been removed for the safety of visitors (rusty barbed wire can be very dangerous). These can still be found in other similar installations (see here). Similarly, the troops and technicians working on site lived in purpose-built housing, segregated from local communities. In Javor 51, this housing still exists, but cannot be visited.

Leaving the place, you can visit the nice visitor/gathering center, and even find some interesting souvenirs!

Getting there and visiting

All in all, the Atom Museum prepared at Javor 51 is a top destination for everybody interested in the history of the Cold War, nuclear warfare, Soviet history, military history, etc.

Credit goes to the owner of the place, Dr. Vaclav Vitovec, who is leading this remarkable preservation effort, and is a very knowledgeable and enthusiastic guide to the site for those visiting. Dr. Vitovec is also the owner of the border museum in Rozvadov, covered in this post.

The Javor 51 site is actually fairly well known at least to a dedicated public, having been visited by historians, scientists and notable figures – including Francis Gary Powers, Jr., who is very active in preserving the history of the Cold War.

The commitment of the museum’s managers is witnessed also by the nice website (also in English), where you can sign-up for a visit on pre-arranged days – as of 2022, all Saturdays in the warm season – or contact the staff for setting up a personalized visit. It is nice to see a good involvement by the local population (the great majority of visitors on regular visits are Czech), including many from younger generations. The exhibits tell much on the peaceful use of nuclear energy, and this is a major topic in the guided tour in Czech. Actually, the Czech Republic has a strong nuclear tradition, with many power plants in use, and a commitment for the development of nuclear energy in the future.

The location is around 25 miles southeast of Plzen, or 60 miles southwest of Prague. Easy to reach by car. The exact address is Míšov 51, 33563 Míšov, Czechia. Full info on their website. Visiting on a normal scheduled visit is on a partly-guided basis, meaning that you will get an intro (in Czech) of around 40 minutes, than you will be allowed to access the bunkers and visit on your own, for all the time you like. You might end up spending more than 2 hours checking out the site and everything is in it, if you have a special interest for the topic. Dr. Vitovec is fluent in English, and can provide much information upon request.

Javor 52 – Bělá pod Bezdězem

The Monolith-type site Javor 52 has been willingly demolished, likely by the Government of the Czech Republic, as it was the case for most other similar (or more in general, Soviet-related) sites in Poland and Germany.

However, it was hard to get completely rid of any trace of an installation so bulky and reinforced. Therefore, some remains can still be found and explored.

Some technical buildings still in use close to the bunkers may have been there from the days of operation.

Getting close to the bunker area, traces of the multiple fences originally around the site can be found, either in the trees or in the vicinity of unmaintained roads. Wooden or concrete posts with fragments of barbed wire are clearly visible. Also reinforced concrete shooting points can be spotted in the wild vegetation.

As typical, two bunkers were erected on site, and similarly to Javor 51 (see above), in Javor 52 they are aligned, with the entrances all along the same ideal orientation.

The bunkers in Javor 52 have been interred, so that they are now hardly noticeable from the outside, except to a careful eye. Looking inside the eastern one, it is possible to get a view of the open doors of the main airlock, providing a distant view of the inner main hall.

Descending through the lateral human-sized airlock is not possible except for a short length, from a concrete manhole on top of the bunker.

The western bunker is in a better general condition, and the main hall still retains a pretty unique writing in Russian. The ladder descending from the suspended platform has been substituted with a posthumous, regular ladder. Much metalwork has disappeared though, including the heat exchangers, the crane, and the tight doors.

Between the bunkers, a concrete pool can be found – still watertight! – with a function which is hard to guess. A pool for civil use was installed in Stolzenhain (and reportedly also in Javor 52, but I had not the time to watch out for it), but this was in the low-security of the site, far from the bunkers.

Getting there and moving around

Access to this place is possible without violating any property sign, but is clearly not encouraged. Going unnoticed is made tricky by the presence of a public facility nearby – a shelter for foreigners and some education activity. Parking out of sight is possible along the road 27235, north of the complex and to the west of the road – trailheads and corresponding parking areas can be found there. Check out some satellite map to find a way to the exact location of the bunkers – their respective entrances are approximately here (eastern bunker) and here (western bunker).

I visited the site in 2020, and the entrances appeared very dangerous and easy to seal in a permanent way. I do not have any further update, but would suggest to go prepared to find definitively interred and totally inaccessible bunkers.

Javor 50 – Bílina – Quick note

As of 2020, the site of Javor 50 is in a peculiar state of ‘conservation’. The place is closed to the public, but entering would be basically unimpeded, since the external fence to the former military base is mostly collapsed and interrupted. The Soviet quarters insider still have much to offer – including writing in Russian, a scheme of the base, and much more. Likely, the bunkers are also still in a relatively good shape.

Much surprisingly though, somebody is living there with watchdogs, in miserable conditions, keeping visitors out. It is likely that an official visit may be booked by getting in touch with the municipality, since it appears that the site is not used for anything. However I was not successful in connecting with anybody there, therefore I have no suggestion on this point. The of the main entrance is here.

The New Life of a Soviet Base in Germany – Ribnitz-Damgarten

Most Soviet bases in the former territory of the German Democratic Republic met with oblivion following the departure of their Red Army tenants back to mainland Russia, in the early 1990s.

Most locations – including full scale airbases (see here, here or here), infantry academies and shooting ranges (see here) and nuclear warhead bunkers (see here) – have been returned to nature, demolished or converted into something else. Much on this website documents this hidden part of the Cold War heritage in Germany.

However, there exist exceptions, like the airbase of Grossenhain with its preserved Granit-type bunker (see here), or the central Soviet headquarters of Wünsdorf (see here).

Another notable exception is that of the former Third Reich, and later Soviet, airbase of Ribnitz-Damgarten. Following an exploration in a day of closure in 2016 (documented here), the site was visited again legit, this time accessing the unique Museum of Technology of Pütnitz. The museum collection is very nice in itself, covering both civil and military vehicles from the DDR age, as well as heavy Soviet military vehicles, and even a few boats and aircraft from the Eastern bloc.

The museum is hosted in a complex of hangars dating from the years of the Third Reich, when the airbase of Ribnitz was active for experimenting with seaplanes, and busy with a facility of the Heinkel aircraft manufacturing company. These concrete hangars are still standing today, undoubtedly an example of German engineering excellence.

The Soviets made good use of this facility, and Ribnitz-Damgarten became a very active base on the Baltic coast for the full span of the Cold War – until the withdrawal of the then-Russian troops, who used this airport as the springboard for their final hop to their new home in Russia.

A further reason to pay a visit to Ribnitz-Damgarten is the chance to assist to the one-of-a-kind reunion and live exhibition of preserved vehicles from the Soviet bloc. Held in the summer, this ‘Treffen’ (i.e. reunion) is really worth the effort of setting up a trip, even when visiting from abroad. It is a multi-day event, and possibly the largest meeting of aficionados of cars, motorcycles and trucks from the communist world, with the chance to see all this good old technology at work, i.e. spitting and thick-smoking, all around the base. Chance is that you will drive on the original Soviet runway to reach the event parking!

Besides this yearly event, the museum offers live demonstrations of military vehicles on a more regular schedule.

The present post and photographs cover a visit to the Technology Museum of Pütnitz in occasion of the reunion of Eastern Europe vehicles held in late August 2021.

Sights

Museum of Technology of Pütnitz

The museum of Pütnitz has taken over the hangars of the old Third Reich base to the west of the airfield of Ribnitz-Damgarten. These hangars are pretty interesting from an architectural standpoint. By using large and curved concrete frames, the inside volume is extremely big for the time. As a matter of fact, they were kept in use for decades, since they could match the size of larger aircraft and vehicles of the Cold War.

These hangars are just a handful, but complemented by smaller (regular size…) hangars they provide for a very large display area, wisely adopted by the museum for its exhibits.

One of the hangars is dedicated to the NVA, i.e. of the Armed Forces of the former GDR. Among the many artifacts on display, are a MiG-21 fighter, the skeleton of an Antonov An-2 transport, and a Mil-8 helicopter. The latter has been placed in a suspended position, with a mechanism to rotate its rotors!

In the same hangar you can find a pretty extensive collection of light armored vehicles, technical amphibious vehicles as well as full-scale tanks formerly in use with the NVA in different stages of the Cold War.

A smaller area is dedicated to a display of NVA uniforms, GDR emblems and medals, uniforms of youth organizations within the GDR, as well as detailed scale models of war material in the arsenal of the USSR or the GDR over the years.

A second smaller hangar hosts trucks of Soviet make, formerly used by – presumably – the NVA. Some are especially interesting, since they were used as missile transports, and are on display with their original trailers and… payload! Also trucks transporting Soviet-made radar antennas, for air target capture or anti-aircraft missile guidance, are on display.

To the back of the same hangar, a super-interesting collection of material connected with nuclear warfare is on display. In particular, field instrumentation for measuring radiation levels, dosimeters, anti-radiation suits and masks, specific medical kits are part of this rich and uncommon exhibition.

Some of the measurement equipment is still working, with old-fashioned, low-light electronic displays still lit – really an evoking sight from the Cold War era!

Yet in another hangar, a huge collection of GDR cars and motorcycles is on display. Most of these now vintage cars and vehicles used to be a rather common sight in the GDR. The now iconic Trabant was a product of the GDR. However, many other car manufacturers existed in the Eastern Bloc, and in the USSR as well, and their products were often exported to other Countries in the bloc.

Stately cars for the top-ranking communist leadership were usually Soviet-made. You can find a small gallery of these Cold War icons in a corner of the same hangar, ahead of giant portraits of the SED (the ruling party of the GDR) leaders – Ulbricht, Honecker, Krenz.

To the back of the hangar, classic motorcycles from the Eastern Bloc are on display. They include MZ motorcycles in use with the Völkspolizei, the police of the GDR. A sizable collection of cameras is also on display.

In the same hangar are a reconstruction of a gas station, as well as a crop-dusting propeller aircraft.

Notably, you can spot fading writings in Russian on the walls of this hangar, an heritage of the Soviet tenancy of the airbase.

Some museum items are on display outside. Some of the military vehicles in the collection are still in working conditions. Live demonstrations of tanks and armored transports are regularly planned, and make for a nice sight and a thrilling experience!

Soviet Relics

Despite having being taken over by the museum and other commercial activities, the premises of the old Soviet airbase of Ribnitz-Damgarten betray the long decades of Soviet use. Besides the relics you can find scattered around in the airfield (see here for a previous exploration), very close to the museum hangars you can spot several technical buildings belonging to the base, and now basically abandoned.

On the side facade of one of those, a colossal Soviet emblem can still be seen, albeit now fading.

Signs written in Russian can be spotted here and there, as well as an original, very interesting full scheme of the base (in Russian too), a typical sight in any Soviet base.

Now-rotting buildings for the base staff can be found emerging from the overgrown vegetation to the north of the hangars.

Finally, the runway is still in a good shape, albeit cut to the east to make room to yet another solar power plant – with a really questionable function, considering the rainy weather physiologically insisting on the region most of the year. The original centerline and other markings can be clearly seen still today.

The airport is closed, but since the runway has not been taken away, perhaps some hope remains for a future with at least general aviation activities, like in Rechlin or Finow.

International Reunion of Vehicles of the Eastern Bloc

Perhaps among the busiest days of the museum in Pütnitz, those of the ‘Internationales Ostblock-Fahrzeugtreffen’ (which translates into the title of this paragraph) make for one of the most exciting occasions for a visit. Usually taking three days, this colossal reunion hosts roughly 2.000 vehicles, from cars to trucks, from farm tractors to motorcycles, from side-cars to firefighting vehicles, and from 4×4 military transports to camping trailers – all made on the communist side of the Iron Curtain!

The reunion is international, and many come from beyond the near border with Poland. In 2021 the reunion hit its 20th edition.

All vehicles are parked in virtually any lot of flat land between and around the hangars of the museum, including the original taxiways and any grassy areas around.

Furthermore, besides some official movements and parade, you will see vehicles moving around at any time, with their very characteristic good old piston engine crackling sound, as well as much spitting and thick-smoking!

Besides the countless Trabants, built in several different versions you will come to discover, chance is to see massive Soviet GAZ military trucks, or even Hungary-built Ikarus buses!

The ‘Treffen’ of 2021 was especially unlucky with the weather, which on the plus side allowed many vehicles to show their all-weather capability!

To better appreciate the noise and smoke, have a look to these three videos!

Visiting

The Museum of Technology in Pütnitz allows you to access the otherwise inaccessible base of Ribnitz-Damgarten. Access is recommended by car. The entrance is to the northeast of the airfield, through the original gate of the airbase. The museum has a website here.

Visiting in normal conditions, i.e. out of any special event, may take about 1 hour, more for a piston-power-minded subject, or for military/vehicles enthusiasts. In occasion of the vehicle reunion, planning a half-day visit at least is recommended, since the display of vehicles is really huge and worth a careful glance. A talk with many nice owners and enthusiasts may be a further plus in this occasion.

The Atlantic Wall in Denmark

A pleasant country in northern Europe, Denmark is geographically surrounded by the North and Baltic seas, and shares its only land border with Germany. In the late 1930s, this meant having a very dangerous dictatorship as the only neighbor, and no possible direct help coming by land from other allies. Without natural defenses against and attack from the south, the Kingdom of Denmark was militarily occupied basically in one day, on April 9th, 1940. This happened through a joint operation carried out by the land, air and naval forces of Nazi Germany.

A quick historical overview

The interest of Germany in controlling Danish territory was mainly strategic. It served as a springboard to attack Norway further north. The latter was in itself more interesting to the economy of the Third Reich, as it was rich of natural resources, including raw materials not available in Germany. These were so needed by the Führer, who was dreaming of making Germany independent from international supply trade.

Furthermore, controlling both Denmark and Norway meant control over the eastern coast of the North Sea, and a chance to control the only access to the Baltic Sea. The USSR was not a declared enemy before 1941, but withdrawing from the mutual cooperation pact with Stalin – signed in a hurry just days before the invasion of Poland in September 1939 – at some point, and openly attacking Russia, had been in the mind of the Führer since he first put on paper his worrying geopolitical thoughts. By controlling the Baltic, Hitler could control sea trade to non-freezing ports of the USSR, which in 1940 had already taken over Estonia, Latvia and Lithuania in agreement with Germany.

As a matter of fact, the conquer of Norway was not without significant losses for Germany. This was also the result of Britain starting to militarily oppose Germany. The two countries had been already at war since September 1939, but without any serious confrontation having taken place for months.

Since then, the British – and later also the American – threat from the west had to be faced through the fortification of the western coast of the Third Reich, which by the end of the summer of 1940 extended roughly from the Pyrenees in southern France to Kirkenes in northern Norway. This highly visionary task was taken up very seriously by the German military-economic machine, and produced the ‘Atlantikwall’ – which translates pretty obviously into the ‘Atlantic Wall’. This long defensive line had to be built all along the coast, and was mainly based on a catalog of standardized reinforced concrete constructions, to be reproduced in great numbers. Construction was coordinated by the main contractor, the German ‘Organization Todt’, which made extensive use of subcontracted local companies in the various occupied states where construction had to take place.

Despite the majority of the elements in the line were reinforced barracks for troops watching the coastline, ammo and supply storages, command and communication bunkers, canteens, and other service buildings, there were of course also a number of heavier constructions. These included coastal gun batteries, to counter attacking ships, lighter gun batteries, to stop troops attempting a beach landing, aiming stations, to adjust the line of fire of gun batteries, anti-aircraft guns to defend the line from air attacks, and some technical buildings serving as bases for advanced radar systems. The latter were among the most useful and widespread items along the line, as German technology developed fast during the war, to produce powerful detection systems against air and sea menaces.

Needless to remember, similar to many pharaonic works conceived by the Führer and his entourage, the Atlantic Wall was never completed, and it failed to spare the Third Reich from total annihilation. The once-modern military installations along the western coast of Europe soon became obsolete, as war changed face at a quick pace following WWII, with new weapons and techniques. Furthermore, the front line of the new Cold War shifted geographically to the middle of Europe. A tangible sign of enemy occupation, the massive bunkers of the Atlantic Wall met different destinies depending on the country. However, albeit only rarely preserved, thanks to their bulkiness and sturdy make, they are in most cases still visible.

About this post

Being the first land along the western coast to fall under German control, work on the Atlantic Wall started in Denmark earlier than anywhere else. Today extensive traces of the line are still pointing the shores of the North Sea.

A few focal points are preserved as first-class museums. These include the strongholds of Hirtsthals and the huge battery at Hanstholm, in Northern Jutland. The latter had been designed around a cluster of four monster coastal guns, to the aim of controlling the passage through the Skagerrak channel, providing access to the Baltic Sea. A twin battery – Vara – was built to the north of the strait in Norway.

Closer to the German border, the area of Blavand – featuring also the famous ‘Tirpitz battery’ in its arsenal – is another example of a partly preserved portion of the line. Bangsbo fort in Frederikshaven has been partly refurbished and opened as a museum, after being used by the Danish military for a while. There you can find one of the few remaining examples of an Atlantic Wall installation with its original guns still in place.

Smaller strongholds, opened as smaller scale museums or left to more adventurous explorers, often feature unique special constructions, which justify a detour at least for more committed war historians. These include the Skagen battery, the disguised bunkers in Thyboron, and the complicated Stauning battery, built on two opposite coasts of a closed firth.

All these sites – and a few more – are covered in this post, which is based on photographs taken in August 2019. Denmark is officially protecting the installations of the Atlantic Wall as historical buildings – unlike France, for instance – so visiting even abandoned sites maybe rewarding, especially if they are out of the mainstream touristic routes. Unfortunately, many bunkers now closer to crowded touristic areas have been damaged by vandals.

Blavand – Shore Battery & Military Area

Located about 50 miles north of the German border along the coast of the North Sea, the small town of Blavand sits on a promontory protruding towards the sea, and protecting the access to the port town of Esbjerg – still today a major commercial port of Denmark.

The area of Blavand saw the construction of an incredible number of Atlantic Wall elements, which grew up in more instances during the war years.

Close by the parking ahead of the lighthouse on the very tip of the promontory, you can find trailheads leading to the southern and western shores of the promontory.

The southern shore makes for a typical North Sea landscape – an endless sand beach. What makes it different from others is the number of light bunkers placed along the shoreline. Despite little imposing, this model – type ‘F’ – was purpose built for the wide shores of Denmark in 1944, in view of a potential enemy beach landing. These firing positions were armed with machine guns, and placed at pre-determined intervals – about 1’500 ft – matching their accuracy range.

Many bunkers are slowly sinking in the sand, and only small parts of them can be seen emerging from the ground.

Others have been turned into strange sculptures, adding a horse head and tail.

Under favorable tide conditions, you may enter some of the bunkers. There you can appreciate their simple structure, with a defensive embrasure by the entrance (looking towards the coast) and loopholes to the sides of the firing chamber.

On the beach close to the lighthouse you can find a very big bunker with a wide hollow cave on the inland side, which used to support a searchlight.

Along the western shore you can find more massive bunkers. These include four former coastal gun batteries. These heavier constructions have assumed strange attitudes, after sinking in the sand somewhat irregularly over the years.

Looking towards the inland from the beach, you can spot an aiming/fire control positions, with a distinctive bulbous roof and a long curved slot on the facade.

Your walk along the northern shore may be interrupted by safety warnings concerning mine threat. As a complement to the defensive potential of the Atlantic Wall, extensive minefields were set up on most of the Danish beaches. This turned into a big issue soon after WWII, when an extensive demining action had to be carried out.

Furthermore, part of the Blavand promontory is occupied by a military firing range. When training exercises are taking place, special warning lights are lit and flags are raised, to delimit the territory where you should not venture.

In the dunes slightly inland from the shoreline, it is possible to find another big number of bunkers. They are not always visible from the distance, and entrance is in most cases from one side only – the only side emerging from the sand.

A very distinctive item is the colossal platform for a ‘Mammut’ type long-range anti-aircraft radar. This used to be operated by the Luftwaffe, whereas other bunkers in Blavand – like elsewhere along the Atlantic Wall – used to be run by other branches of the Germany military.

The base for the radar is in itself a rather complex bunker, with several cavities and extensive piping, once needed for power cables feeding the antenna, as well as other wiring.

Close by, a smaller radar base bunker used to be operated by the German Navy. Also here, holes and passages for cables can be found in the walls and roof.

It is noteworthy how many bunkers feature traces of original decorations, like painted walls, fake wallpaper, frescoes and small frieze lines. This is typical to many other installations of the Atlantic Wall.

Metal hardware can be found in the form of a bulky aiming turret emerging from a bunker.

In another instance, a mortar mouth pops out from the ground.

The underground bunker underneath the latter can be explored with some difficulty – there are also quite annoying bats inside -, but it reveals an aiming wheel with original markings in a reinforced concrete dome!

An interesting sight nearby the lighthouse is the tower once supporting a ‘See Riese’ radar. The protruding arms once sustained a wooden platform for military operators.

Getting there and moving around

The area of Blavand is rather extensive and rich of diverse installations, so notwithstanding the general bad shape of most of the bunkers, visiting may easily take 3-4 hours for a committed tourist, getting inside most of the items. A good starting point is the free parking by the lighthouse, provided you come early especially in summer, cause it tends to get more and more crowded along the day.

Blavand – ‘Tirpitz’ Coastal Guns

Despite at least some of the bunkers on the shores of Blavand being in a relatively good shape, there is a part of the Atlantic Wall which is officially preserved as a museum. This is one of the two unfinished bunkers intended to support a set of massive 38 cm coastal guns.

These guns – four, two for each bunker – were originally intended to be put on board battleship Gneisenau. The latter got damaged in port, and the guns were diverted to coastal use. The decision to build the Tirpitz battery to protect the port of Esbjerg came relatively late during the war, in 1944. As a result, construction of the battery supporting structures was not completed when the war ended, and the four never installed guns were scrapped – except one, which can be admired in Hanstholm (see below).

The name ‘Tirpitz’ attributed to this battery is of uncertain origin, and sometimes this installation is also referred to as ‘Vogelnest’.

The museum has been built only in the southernmost bunker. The installation is very modern (and crowded), and it has been designed as a thematic museum in five sections. Two of the most interesting are about the Atlantic Wall and its impact on local life, and on the extensive mining and demining operations on the shores of Denmark.

Other sections are related to amber trade and local seamen activities.

Finally, you can get access to the base of the gun turret. Photographs are bad here, due to very poor lighting and limitations on camera use.

You can see a central round dome, surrounded by an external corridor. Traces of a post-war explosion can be noticed looking at the metal part of the construction.

Outside of the museum you can find a cannon cut in pieces, plus rigs used for construction. The bulky concrete arms protruding from the roof were meant to support the crane for mounting the cannons.

With a five minutes walk from this bunker, you can get to the northern battery. This is not preserved, and the entrances have been bricked up. Yet you may better appreciate the size of the bunker from this exemplar than from the one turned into a museum.

Getting there and moving around

The museum is located east of Oksby along Tane Hedevey, a local road connecting Blavand to Esbjerg. There are signs along the road, and a large parking ahead of the entrance. The museum is very modern, and may turn very crowded in summer. Website with full information here. You can visit on your own with an audio-guide. The visit to the military-related sections may take about 1 hour.

Adding a walk to the northern battery will take further 20 minutes at most, as there is no chance to step in.

Stauning Battery

Construction of this battery started in the second half of 1944, and consequently it was only partially completed before the end of the war. The geography of the Stauning battery is rather peculiar. The intended design was based on four coastal guns to be placed on the inland side of the Ringkobing firth – basically a lake with a channel-like small mouth connecting it to the sea. On the other coast of the firth, i.e. very close to the North Sea in Hvide Sande, the aiming station for the battery was finally built.

In the event, only one of the reinforced concrete gun positions reached completion, whereas the other three cannons were kept on basic, not reinforced aprons. The gun bunker is the only exemplar of this model built along the Atlantic Wall, and was designed around a 19,4 cm gun manufactured in France.

Located far from the shore in a secluded area of the countryside, this battery is in a relatively good shape, and thanks to the hard soil its position has not drifted since it was installed. You can even walk on top.

More elements are scattered in the bushes and over the private pasture nearby. Among them, a firing position presumably for anti-aircraft or light field guns, and corresponding ammo storages.

There is also a reinforced concrete barrack or command post. This can be toured inside, revealing some metal piping still in place.

Traces of gun concrete platforms – likely gun firing positions – blown up after the war can be seen, similar to many smaller cubic buildings of uncertain purpose.

A couple of unattractive half-interred ‘living bunker’ can be found too, another design present only in Denmark – the type was named ‘Falkenhorst III’. Inside, traces of original wall paintings can be easily spotted.

There is actually a fire direction post of some sort in this part of the battery too. This is a square-based concrete booth, with an adjoining living bunker.

The aiming position in Hvide Sande is rather easy to find, on top of a mound close to the city center. There are actually two concrete accesses on the eastern side of the hill. The one closer to the top gives access to the metal dome you can spot on top of the mound.

Climbing up to the dome is possible along a rusty ladder, going through a narrow vertical passage. Once there you can see the mounting of a telescope for measurements. There are side slots looking outside, and an original marked wheel to provide measurements. You can also spot small foldable wooden tables (or perhaps jump-seats).

Downstairs, there are a few panels explaining the history of the battery.

The second concrete entrance gives access to a ‘living bunker’ for the troops, with explanatory panels on the history of the place.

Getting there and moving around

The inland part of the Stauning battery with the gun station is located close to Stauningvej 55. You may park your car not far north from this address, on a wide lot close to the entrance of a local residential area. Most notably, this battery is about .5 miles from the beautiful Danish Museum of Flight (see this post). Exploring the battery may take 1-1.5 hours, as the place is totally wild and inconvenient to visit.

The Hvide Sande point is on the northern rim of the channel linking the firth to the North Sea. You can see the mound close by a major round about, where road 181 meets Troldbjergsvej. There are several parking options nearby. The place is technically not abandoned, but there was no ticket/staff, and it was totally dark when I visited. You would better take a small torch with you.

Sondervig

Just as an example of how extensive the construction of the Atlantic Wall was in Denmark, you may have a look to the beach in Sondervig, where people spending the day by the sea are accustomed to the view of the monstrous German bunkers pointing the shore.

Getting there and moving around

You may find a parking spot in Sondervig and access this famous touristic beach by foot.

Thyboron

The coastal battery at Thyboron has a unique place in the panorama of Atlantic Wall buildings. Here a sort of sample list of possible deceptive techniques were tested on otherwise normal bunkers. The usual constructions pointing the shore have a strange appearance here, thanks to the imaginative talent of a Danish architect – who turned out to be a spy working for the Allies.

At least two gun batteries bear a special roof, resembling that of a house. Also thanks to erosion, they now have even odder shapes, resembling some Star Wars spaceship.

An observation bunker bears a tiled roof. Surprisingly, an apparently original fragment of telegraph wire can be found inside.

Given the position of the bunkers – lying isolated on a deserted beach – it’s pretty difficult to suppose this kind of deception was ever effective…

There are also some more straightforward constructions around, some of them in a relatively good shape. The cusped lintels above most doors and openings are typical to elements of the Atlantic Wall in northern countries, and are made for protecting the passages against snow and icing rain.

Just inland from the ‘sample list’, you can find a large underground bunker, somewhat difficult to access – it is sinking in the sand. Conspicuous traces of original wall painting and even writings in German can be found on the walls.

The message in German is a warning message, telling to stay away of the walls in case of bombardment. This warning sign is rather ubiquitous in Danish bunkers.

Close to the the city center – and actually a part of the Coastal Center, a museum for children dedicated to the life along the western coast of Jutland – it is possible to find another bunker deceived as a wooden house! This deception technique is far more convincing than those on the shore…

Getting there and moving around

To visit the bunkers on the shore you can reach a convenient public parking at the southern end of Vesterhavsgade, southern Thyboron. Visiting these bunkers may take about 45 minutes for a committed tourist. To get to the Coastal Center you may follow the signs and park at your convenience ahead of the building. The deceived bunker can be seen from the outside of the museum, so getting the ticket is not needed if you are not interested in the rest of the installation.

Extra feature – Sea War Museum, Thyboron

Thyboron has a prominent place in WWI history, being the Danish village closest to the area of the Battle of Jutland, one of the very few naval battles of that war, and one of the top-ranking in history for the number of vessels and tonnage involved, and for the casualties – almost 9’000 seamen were killed.

The battle was fought between two major formations of the the German Kaiser on one side and the King of England on the other. Started almost by chance, as the two opposing factions appeared on the same sector unaware of each other, the fighting was so intense that cannon fire was heard along the shores of Thyboron for many hours. The battle ended with a tactical defeat on the British side, but the Kriegsmarine of the Kaiser avoided any other serious clashes with the British for the rest of the war – in this sense, this was a British strategic victory.

Today, a monument dedicated to those who perished in the Battle of Jutland occupies a wide area over a promontory in northern Thyboron, close by the Coastal Center (see above).

A nice museum dedicated to sea war has been put in place nearby. On the exterior you can find old mines, torpedoes and even parts of relics taken from the bottom of the sea.

Inside you can find many unique artifacts, including cannons, insignia, and everyday items from ships taking parts to the Battle of Jutland.

Also unique are parts of early submarines dating from WWI, recovered from the sea thanks to novel investigation and capture technologies.

The museum is at large dedicated to naval battles and ventures of WWI. A section is dedicated to the most modern sea archaeology techniques.

Outside of the museum, you may spot a few Atlantic Wall bunkers as well, likely converted into more modern military installations in a post-WWII period. They are apparently run as museums, but they were closed when I passed by.

Getting there and moving around

The Sea War Museum is located very close to the Coastal Center in central Thyboron. Dedicated free parking right ahead of the entrance. Visiting may take about 1.5-2 hours for more committed subjects, despite the small size. The museum is stacked with extremely interesting details, the exhibition is rich and well made. Really an interesting detour for anybody interested in sea war. Website here.

Agger

Agger is located north of the Thyboron Channel, and can be reached with a five minutes ferry ride from nearby Thyboron. The long, windy, wild and distressing beaches south of the village of Agger are not really welcoming, nor easy to visit. Yet here you can find some unique and imposing elements of the Atlantic Wall.

These include a firing control bunker of the Navy. A feature often found also elsewhere, you can see some of the concrete bunkers are made of joined blocks. Light can be seen coming from the thin slots between the blocks in some occasions.

Another special construction here is the support tower for a ‘Seetakt’ radar. The tall concrete tower is assembled together with a bulkier concrete base.

The assembly has slipped to the shoreline, and today it can be neared only in favorable tide conditions. Furthermore, it is sitting in a banked attitude, making it looking really derelict.

Thanks also to a rather bad weather, these elements of the Atlantic Wall looked really eerie when I visited!

Getting there and moving around

The Agger site is wild and not signaled. The area is part of a national preserve, and part of the endless beach is a stage for kites, surfing activities and other beach sports. There is an official parking at the western end of Lange Mole Vej, less than five minutes by car from the ferry terminal to Thyboron. From there you should go to the beach and walk north for about 15 minutes to get to the tower, the highlight of the show.

You may spot it from the distance. I could not get in the tower due to unfavorable tide conditions, but visiting inside may not take much time, for the expected condition is not good, with little left to see.

Hanstholm

The Hanstholm battery is one of the most developed of the entire Atlantic Wall. As pointed out in the introduction, together with the sister site ‘Vara’ in Norway – about 80 miles north – this battery was centered on four massive 38 cm cannons, installed to obstruct surface passage through the Skagerrak, and de facto controlling the access to the Baltic Sea.

An initial battery based on less powerful 17 cm coastal guns was put in place as soon as 1940. The gigantic 38 cm guns arrived only later and were tested, but never used in action. The metal parts of the firing stations, including the turrets and guns, were eventually scrapped in the early 1950s. Over the years, this huge installation, with more than 300 bunkers fell largely into private hands, and today many former storage bunkers are used as warehouses for machinery and goods by local owners.

Nonetheless, battery Nr.3 has been turned into a modern museum, after being largely refurbished to its original splendor. As such, it is a one-of-a-kind museum, with thousands of visitors per year. Two more turrets and a number of bunkers are left to explorers. While they are not actively maintained, they are still in a rather good shape, and responsible exploration is even supported with some indications.

The area of the Hanstholm is almost 4 square miles. In order not to get disoriented, a good starting point is the museum in and around turret Nr.3. There you are greeted by a pretty unique 38 cm cannon! This is actually from the Tirpitz battery (see above), but it is exactly the same item once installed in Hanstholm. The size is really remarkable, especially when compared to more modest and usual 15 cm coastal guns, on display.

The modern museum offers a quick recap of the history of the place, with memorabilia including everyday items, letters, maps and original weapons.

Once you are done with that, you can get access to the underground part, where you first meet the ammo storage rooms, on the side of a long corridor aligned along a narrow gauge railway track. This was used to connect the firing stations – i.e. the four bunkers with the guns – to larger ammo storages scattered around the are of the fort.

There are two major adjoining rooms along the corridor, each dedicated to a different part of the cartridge. The piercing part – the ‘bullet’ – and the exploding fuse were kept separated from each other. This is similar to naval guns, and typical to larger calibers. The complicated railings hanging from the roof were made to allow moving the parts of the cartridge by means of movable cranes.

In action, the bullets and fuses were loaded on a slide, and from there on trolleys which would enter the turret from below. Today, as the turret is not there any more, the trolleys are in an open air corridor, apparently without any sense. It is noteworthy that the inscriptions and frescoes are all original, albeit refurbished.

The structure of the firing station and of the Hanstholm fort can be better appreciated from the drawings and models below.

A second part of the firing station is the bunker for the complement of men needed to operate this complicated cannon. The place was permanently watched, with shifts spending the night in underground quarters. Those pertaining to firing station Nr.3 have been refurbished, and provide a vivid impression of the original appearance. There are sleeping and living quarters, as well as large, military style showers and toilets.

There is also a complete power station, with two Diesel generators, a mechanics shop, water tanks and more.

Out of the Nr.3 firing station you are encouraged to tour at least part of the site along a series of prescribed trails. Among the items you meet on this tour is one of the ammo storages. It is not dissimilar from the ammo storage part of the firing station. The ammo parts were loaded on a railway car passing through, and from there moved towards the gun turret.

There are also many smaller storage and service bunkers, some bearing interesting original inscriptions inside.

The Hanstholm fort was defended by field cannons and anti-aircraft guns. Emplacements for the latter can be spotted around in more instances.

Another suggested part of the visit is firing station Nr.4, which is not really preserved, but is not in a generally bad shape either. You can get in only if you have a torchlight. Visiting may offer something very similar to Nr.3, except everything is more derelict – but for this reason, may be more authentic.

In the living part, you can find inscriptions in German and traces of the original wall paint. With a general knowledge of the plan from the visit to Nr.3, you may easily recognize the corresponding rooms – power station, toilets, living rooms, etc.

To get to the ammo storage part, you can walk along the round corridor outside. No trolleys left here, differently from Nr.3.

Inside the ammo storage rooms, you notice that the inscriptions have been largely canceled for some reason, but the slides as well as the frescoes above them are still there.

Still part of the suggested itinerary, you can find a control station, in a rather bad shape, and more interestingly a very peculiar building, located on top of a cliff.

This was a fire direction station. Due to the high-tech nature of the Hanstholm battery, fire direction worked on what can be considered archaic computers! The building has many floors. There is provision for a permanent team of technicians, hosted in living and sleeping quarters downstairs.

The top floors used to host the computing machines, which were fed by measurements from instruments mounted in metal domes, facing on the roof of the building. The room for the computing machines is rather dark, and due to the black walls it is difficult to see anything even with a torch.

The Hanstholm site offers several ancillary bunkers open to the public. Among them, one for a generator, supplying the whole fort in case of a grid failure.

Another bunker is an ammo storage, with a big concrete arch outside, for a moving crane operating above railway cars. Narrow gauge railway tracks can be seen still today in this part.

The pivot in the middle of firing station Nr.2 has been interred after the war, but the living/sleeping quarters for the troops and the ammo storage parts can be visited, albeit they are not connected any more by a direct passage.

A visit to this firing station is very interesting, for writings are in a generally better shape than in Nr.4, even though this too has not been refurbished.

In the ammo storage part, writings are especially abundant. You can see also traces of the original telephone wiring.

The last firing station, Nr.1, is not accessible, even though not interred.

As said, there are many other bunkers an remains around, which are typically not accessible, especially the farther you go from the museum. They are now largely on private land and used for something else.

Getting there and moving around

The Hanstholm strongpoint is a must for everyone interested in the Atlantic Wall! The museum is modern, completely accessible, with a convenient parking and all usual facilities. Website here.

The refurbished part is basically only firing station Nr.3, but many other bunkers, like the fire control center, as well as firing stations Nr.2 and 4 are open for explorers, and they have not been spoiled by vandals. You need to go with a torchlight and proper clothing, but the visit may be very rewarding.

Many more bunkers around are closed to the public, as they are now private property and used for other purposes.

Due to the enormous size of the area, visiting may easily turn into a full-day or even multi-days business for an enthusiast. For the general public, a visit to the museum and one of the trails may take a 2-3 hours depending on the level of interest.

Hirtshals

Similar to Hanstholm (see above), the area of Hirtshals was soon selected by the Wehrmacht for a coastal fortification, thanks to its strategic position overlooking the mouth of the Skagerrak strait.

The first four 105 mm field guns were positioned here as soon as summer 1941. They occupied open-air concrete aprons, which still today bear trace of the original camouflage paint and deceptive net.

A peculiarity of this fort is its extensive network of trenches, which connect all the battle stations to the living quarters for the troops and the service buildings, like the canteen-bunker and the hospital-bunker.

On top of the steep cliff dropping to sea level, you can find the bunkers for the guns. These were moved from the open aprons in 1944, into purpose built reinforced concrete firing positions. A special feature here is the steep flight of stair giving access to the gun area from behind. This construction was made necessary by the particular morphology and rock type of the cliff.

You can spot significant traces of the original camo paint, and the letters ‘St’ on many walls, meaning ‘Ständig’, i.e. resistant in German. These letters were used to mark those buildings capable of sustaining shelling and bombing raids.

A bulbous roof allows to easily recognize the fire direction station.

A more rare item in Hirtshals is the base for the ‘See Riese’ radar. This is a hexagonal concrete hollow platform. The bunker underneath it would serve to host a Diesel power generator.

Back from the coastline, you may enjoy a long exploration of the trenches and of the many restored bunkers. Many bear original markings and paintings.

In some rare cases, you can also find original decorative paintings, likely made by the soldiers stationed in the bunkers.

Restored bunkers include a ‘living bunker’, but many other installations are in good conditions, like interred shelters, ammo storages, etc. Traces of cables, armored doors – some of them with glass lights – and telephone wires can be found in many bunkers.

Furthermore, in Hirtshals you have the chance to get a bird’s eye view of the fort, by climbing on top of the local lighthouse!

Getting there and moving around

The Hirtshals site is an open-air museum. There are technically opening times, but the area is not fenced, so if you are looking for a visit to the exteriors, you can walk around freely at any time. The museum has a website here, and guided visits are offered in many occasions. Many bunkers were closed when I visited, and they might be visible only with a guide. Some other bunkers are open and lighted, whereas the majority are basically left to explorers – open and not lighted – but rather accessible and very easy to visit, maybe with the help of a small torch. There is not a clear entrance (the area is not fenced), nor permanent staff on the site.

There are explanatory signs for basically all of the bunkers, in double Danish/German language.

The parking is ahead of the lighthouse, which is a different entity and operates with opening times you can find here. The parking is large and free. Climbing on top of the lighthouse is possible at a small fee – apparently only Danish Crowns cash accepted.

Together with a climb on top of the lighthouse, the visit may take from 1.5 to 3 hours, depending on your level of interest.

Skagen

The Skagen area is mostly famous for its location on the very tip of the Jutland peninsula, the natural northern end of continental Europe, and ideally as the geographical point where the North Sea and Baltic Sea join together. The long and quiet shores there and the population of seals contribute to making Skagen a prominent touristic attraction, often crowded with visitors from Denmark and abroad.

What people going there may not expect is the presence of a number of massive firing positions from the years of the German occupation! These are concentrated along the eastern coast, and include firing position for 120 mm coastal guns, overlooking the Skagerrak strait.

There are also a fire control bunker, which has drifted to the shoreline, as well as radar support bunkers.

Unfortunately, these installations have been left to the elements and – most sadly – to vandals. Except for their huge size, there is not much left to appreciate.

But there is more related to the Atlantic Wall in Skagen. A former hospital bunker has been partly refurbished and converted into a very interesting smaller museum on the local battery.

Inside, you can first appreciate the special size of the doors and corridors, made to allow moving stretchers around.

Put on display are several items related to the history of the Skagen fortress. There are uniforms from the time, photos from the years of operations, and everyday items left over by the Wehrmacht.

Some of the rooms have been reconstructed, and provide a vivid impression of the original appearance.

Among the exhibits are also some relics from a downed British aircraft.

Getting there and moving around

Visiting the Skagen battery is easier from the small parking Hvide Fyr, Fyrvej, 9990 Skagen. This parking is free. Going on the Baltic shore from the parking means a five minutes walk along a prepared path. A quick walk with a look to the abandoned battery would take about 20 minutes.

You may either walk to the tip from there, or better move your car to shorten the walk, going to the huge dedicated parking area where the road N.40 ends. This parking is not free.

You will find the Skagen Bunker-Museum in the former hospital bunker immediately to the southwestern side of the parking. Website here.

Visiting may take about 30-45 minutes, an interesting small detour from the local natural attractions.

Bangsbo

Comparatively less fortified than the North Sea coast, the eastern cost of Jutland is the place of a primary military and commercial port named Frederikshavn. This is also a starting point for travelers going to Norway from central Europe.

Here the Germans installed one of the few strongpoints on this side of the peninsula. What makes the so-called Bangsbo fort unique among the Atlantic Wall installations is the fact that three of the four original guns in the coastal battery are still in place!

The main area of Bangsbo fort, where the coastal battery is located, can be found to the south of the town, and is somewhat similar to Hirtshals (see above). Both are located on top of a cliff, with a significant area to the back dedicated to command, living and service bunkers.

Today, some of these bunkers have been completely refurbished. These include the command bunker for the local commander of the Kriegsmarine (the German Navy). This is super-interesting, with many artifacts from the time, from military gear to swastika-marked dishware, from maps to photographs of general Rommel – who superintended the construction of the Atlantic Wall – visiting the installation, and much more.

Much interesting is especially the reconstruction of the command/meeting room.

Scattered over the premises of the military area are cannons and several strange items, like a tank turret intended to be placed on top of a defensive Tobruk.

There are a refurbished hospital bunker and reconstructed living quarters.

The firing control post roughly at the center of the area is another highlight, having been completely refurbished, with plenty of Nazi insignia and original material.

To the back of the bunker are a living and command area, whereas the front part is an observation deck.

The firing positions with guns are numbered from Nr.1 to 3. They are based on 15 cm coastal guns, installed in 1944, replacing older and smaller pieces.

The guns can be walked around. The cartridge supply slides to the back of the firing chamber are still in place.

Guns Nr. 1 and 3 are similar, whereas the central gun was taken from a Danish cruiser cannibalized by the Germans in Kiel during the war. Today, it bears a greenish paint.

There used to be a fourth cannon with a field of fire of 360 degrees. Trace of a platform can be seen, as well as an anti-aircraft gun.

The fort shares a border with an active military area, so a part of the original installations cannot be visited. Others are open only for those visiting on guided tours. These include a radar-supporting station. Others can be entered, but are basically empty.

A minor part of the Bansgbo fort is located north of Frederikshavn. It is a partially preserved anti-aircraft firing station. This was made of four firing places and a central fire direction point. The latter is still visible at least from the outside.

One of the anti aircraft guns is also in place. The rest of the installation has been filled with land and made inaccessible.

Getting there and moving around

The major part of Bansgbo fort can be found south of Frederikshavn. It can be accessed from Bakkevej, which ends with the parking of the museum. Website here. The area can be walked and accessed with a ticket. There are picnic facilities and a small shop. Guided tours are offered at pre-defined times, see the website. You can get a good impression even by walking around on your own, but some bunkers can be accessed only with a guide. I did not join a guided tour, and all the pictures above are from a self-guided visit.

The site is not huge, but very interesting thanks to preservation efforts. It may easily deserve a 2 hours visit.

The anti-aircraft site is located north of Frederikshaven, and can be reached from Nordre Strandvej. You may park on the large free parking made for the local beach. This smaller installation may be visited in 10-15 minutes without a ticket.

Cold War Forts and Museums in Denmark

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.

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.

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.

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!

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.

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.

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.

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.

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.

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.

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.

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…

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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!

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.

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.

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.

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…
