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.

The Red Army in Hungary – Airbases, Bunkers and Ghost Towns

Similar to other satellite countries like Poland, Czechoslovakia and the former German Democratic Republic, for decades after WWII Hungary was under the strong influence and de facto military control of the Soviet Union. As a result of the anti-communist revolution of 1956, when the Soviet nearly lost control of the country for a while, a massive Soviet force was stationed in Hungary to prevent further turmoil – the so-called Southern Group of Forces – acting in parallel with the local Hungarian Army, although in a coordinated fashion.

This was reflected by the turning of several existing airfields and training grounds from older times into modern Soviet bases. Their premises, and the territories around them, were completely severed from the rest of the Country, leaving the Soviet forces with a great freedom of action concerning the deployment of unspecified numbers of troops, tanks, aircraft, communication gear, and even nuclear warheads. Furthermore, the families of the Soviet troops stationed in the Country were hosted in dedicated purpose built – or purpose converted, pre-existing – villages.

All this left traces of course, and after the end of communism in Europe, and later the collapse of the USSR, the majority of these installations were either abandoned or converted to some other use. Abandoned – i.e. not converted – Soviet bases and installations in Hungary were pretty many. Today, many of them are being demolished, or are still standing, but severely damaged after years of disrepair. Actually, the best preserved installations are those waiting for conversion or for some yet-to-be-defined destiny, and currently under custody of private owners or the state.

This post is about some of these installations, and it focuses especially – but not exclusively – on storage bunkers for nuclear warheads. Besides being especially appealing to mystery-hunters and urbex explorers, such places are an interesting testimony of the serious attitude of the Soviets towards a war in the European theater. This was considered a likely event in many instances over the decades of the Cold War, from the 1950s to the years of President Reagan’s Strategic Defense Initiative. The money spent over the years by the Soviet Union to build up a dedicated military infrastructure, and the deployment of tactical warheads close to the designated targets in western Europe to prepare for such scenario, show that the USSR did not think of fighting a nuclear-based final battle just as a mere theoretical exercise.

Photographs were taken in August 2020.

Sights

Based on a CIA report dating from 1979 (‘Warsaw Pact Forces Opposite NATO’, Vol.I-II, CREST record number 0005517771, declassified and released in 2010, check it out here), there used to be a small yet significant number of bunkers for the storage of the Soviet nuclear stockpile in Hungary. The following map, taken from this report, shows their approximate location and type.

Despite a clear correspondence of each symbol with a Soviet bunker construction type is not readily available, it is possible to reconstruct the information as follows.

The only solid triangle corresponds to a Monolith-type storage bunker, the largest and most sophisticated type of storage in the Soviet standard inventory, made for long-term storage of nuclear warheads. This site is located close to the village of Urkut, in the middle of an extended region, once the largest part of Hungary managed exclusively by the Soviet military. In this area you can find also the headquarters of the Soviet forces in Hungary, the Southern Group of Forces, located in the small village of Hajmasker, as well as the airbase of Veszprem, with an annexed village with housing for military staff and their families.

Monolith-type bunkers were seldom built on the premises of airbases or other military bases. They were prepared mostly in secluded area, shrouded in the vegetation, so as to avoid any unwanted attention as much as possible. They would store high-yield warheads for theater missiles (e.g. SCUD missiles). Urkut is no exception, as there are no airfields close to it. It is shrouded in the vegetation, and far from any village of significant size.

Back to the map, round dots represent Basalt-type storage bunkers, which are most commonly to be found close to airfields. This type of bunker is significantly large, and capable to store air-dropped/launched tactical weapons with nuclear warheads. Two sites are shown on the map, of which only the one on the premises of the former airbase of Kunmadaras could be located.

Finally, the squares correspond to Granit-type storage bunkers. These were of much lighter construction with respect to Monolith and Bazalt, and their purpose could be that of hiding either missile launchers of various size, or command/communication posts. Much has to be guessed about the actual function they had in all places where they were built. In Hungary, three such bunkers are reported on the map, of which the easternmost is on the still active airport of Debrecen, the westernmost is on the small local airport of Heviz (formerly Sarmellek), and the latter is presumably on Tokol, a major airbase in the outskirts of Budapest, Hungary capital city.

In the following you can find some pictures from the storage sites of Urkut, Kunmadaras and Sarmellek, plus pictures from the Soviet bases of Veszprem, Tokol and Kalocsa, and from the former Soviet headquarters in Hajmasker.

Urkut Monolith-Type Nuclear Storage Site

The Urkut site is also familiarly known as ‘little Moscow’, due to the fact that this site hosted also a very small, perfectly Soviet-style quarter for the troops working on the base, or being trained in the local training center. The site is in a wide and pleasant valley with a north-south alignment. There used to be two access roads which today take from the main (and only) road running along the mostly uninhabited valley, connecting Urkut (to the north) and Nagyvazsony (to the south). The two access roads take you to the main gates, placed to the north and south ends of the complex.

Similar to other nuclear sites based on the Monolith-type bunker model (see for instance this post for an accurate pictorial description of another one), security was clearly a major concern. Still today, walking in the trees and approaching the base without going the official access roads, you will meet four external fences.

The outer one is made of concrete posts and barbed wire, but today this is mostly gone – which makes it practically more dangerous, as the few remnants of suspended barbed wire are barely visible, and much leftovers are partly hidden by the abundant low-growing vegetation.

Next you will come to a concrete wall made of prefabricated slabs, with traces of barbed wire on top. This is still today basically impenetrable.

Once in, you will find two further lines of barbed wire, suspended on concrete posts. This double fence of barbed wire is still in very good shape, and creates a watch corridor.

Inside the perimeter, you can spot a network of trenches and foxholes.

In Urkut, the training grounds and bunkers are close to the northern gate, whereas to the south you can find the former living quarters for the troops. A prominent training hangar can be found in the northern part of the base.

Inside, a perfectly conserved mural with the heads of Marx, Engels and Lenin, and Moscow’s Kremlin in the background, is still hanging on top of the main gate.

Along the hangar, a corridor with classrooms clearly shows the intended function of the building.

Not far north from this major attraction, you soon meet a smaller technical building, and the southern Monolith bunker close by. Bases centered on the Monolith type typically had two independent twin bunkers built onsite, usually with their axes tilted by 90 degrees, so as to minimize the chance of a single bomb effectively striking both bunkers. This is not the case in Urkut though, as both bunkers are built along an East-West direction. Urkut is different from other Monolith sites also for having been built on the slope of a hill, so connection roads are never flat.

The warheads reached the bunker by truck. A covered loading/unloading platform can be found on both opposite entrances to the bunker. For the southern bunker, you can see in the pictures the platform is still in very good conditions, with colored signs on the pavement for facilitating movements. Even the lamps are still there!

The main access to the bunker was via an airlock, with two gigantic square-shaped blast-proof doors on each side. In this pictures you are seeing the western access to the southern bunker.

The innermost part of the Urkut bunkers is inaccessible, as the inner doors of the airlocks are shut. Yet it is possible to get access to the airlocks. For the southern bunker, going to the eastern access you find a covered platform similar to the western one, yet here the roof has partly collapsed.

You may open the outer door of the airlock, and get access. Here you can see writing in Russian. The state of conservation is generally speaking extremely good.

On one side of the eastern loading platform, you can see a standard Soviet military transportable trailer, maybe a local operation control center.

In order to get to the northern bunker you need to climb uphill, crossing some further inner fences – it was typical to Soviet bases having multiple fences inside military bases, separating parts with different functions and levels of security.

While loading platforms of the southern bunker are tilted by 90 degrees with respect to the axis of the bunker, for the northern bunker they are aligned along the same direction.

The eastern access to the northern bunker features is fairly well conserved. Also here, it is possible to access the airlock, but the inner gate is sealed.

On top of the northern bunker, you can find the ‘pedestrian access’ to the underground cellar. The gates used to carry the warheads in and out were usually kept closed, and the troops or technicians staying inside the bunker, which had provision for a few men overlooking the sensitive ordnance 24/7 in shifts, could enter and leave the bunker via a more modestly sized hatch. This could be reached from the top of the bunker, descending very steep stairs to the level of the bottom of the internal chamber. There you had an airlock, with tight doors the size of a man. These are closed in Urkut, but you can see the external tight door in its original yellow coating with conspicuous writing in Russian.

The soft construction protecting the access to the stairs is today severely damaged.

Finally, the western entrance to the northern bunker is very similar in shape to the eastern one. The northern gate of the complex is not far from here.

Also here, the airlock can be accessed, but the bunker cannot be entered.

All in all, the Urkut site is in an exceptionally good condition in the panorama of Soviet remains. A conversion into a museum would be highly desirable, and would require a very little effort. The fact that the bunkers are closed clearly suggests the inside was not touched, so maybe only basic renovation would be required to make the place a top-notch attraction for Cold War history enthusiasts.

Getting there & Moving around

The site is either on private land or state-owned. In any case, it is not officially accessible. The access roads are guarded, with people (and watchdogs) living on site. Car access on the access road is not allowed either. Walking on the site you may find several vibration sensors with cable connections likely to the booths close to the main access. For these reasons, further indications on access will not be provided.

Soviet Headquarters at Hajmasker Castle

Similar to Wünsdorf in Germany (see this post), Hajmasker Castle was built just before WWI, the focal point of a large military settlement of the Austro-Hungarian Empire. During WWII, it was used as a military command center, and as a local headquarter of the German Army in the latest stages of WWII, when the willingness of a part of the Hungarian establishment to put a quick end to the war by negotiating a peace treaty with the Western Allies caused the Germans to take direct control of that war theater.

After the defeat in WWII and the Soviet invasion, since 1945 the castle hosted the headquarters of the Soviet military in Hungary – just like Wünsdorf in the German Democratic Republic. Again in a totally similar fashion, the symbolic end of Soviet dominance in Hungary was marked by the last train for the Soviet staff leaving Hajmasker for the USSR in 1990.

As said, the castle is what remains of a larger military village. The building is really sizable, with a characteristic prominent tower on the front facade.

Walking around the castle you can find a theater hall opposite the tower.

The walls are pierced, so you can see inside, without getting access to the hall, which appears really one step away from collapse. To the back of the castle you can find traces of a large apron for military use, and direct access to the railway nearby.

Back to the tower, the original gate is not made for large vehicles, and the gracious artistic style of the construction clearly suggests a pre-Soviet design.

Climbing upstairs, you meet long corridors with traces of the offices of the top-ranking men from the Soviet military. Hajmasker is strategically located close to the region where the Urkut site is (see above), and where the former base of Veszprem is also located. The place is less than one hour from Budapest.

The view from the top floors of the building further reveals the size of the castle, together with the poor state of conservation.

Ahead of the entrance, a Soviet-style apartment block can be found, still inhabited today. Smaller buildings are all around the castle, both modern or from the age of the castle. You can find also the flat building of a former canteen, clearly Soviet-designed and today abandoned.

Getting there & Moving around

The place is located at the following GPS coordinates: 47.148319, 18.026145. The castle is formally off-limits, but it is totally abandoned and accessed by writers, creepy-ambience-lovers, as well as by the local population. You may park right ahead of the gate among the cars of those living in the local neighborhood. You will be spotted for sure when accessing, but nobody will likely interfere, as access is totally easy (no fences, no barbed wire,…), despite being formally prohibited. Enter at your own risk, as the building looks really rotting, with the roof partly collapsed, exposing wood and bricks as construction materials – considering their age, the high rise of the building and total disrepair over the last decades, this means high risk.

Veszprem Abandoned Airbase & Ghost Town

The old airfield in Veszprem acted as a major helicopter base during the Cold War, but style of the some of the older buildings betrays its 1930s origin as an airbase with annexed training academy. Of course, the Soviets enlarged its structure, and possibly as late as the 1980s they built massive housing in their typical poorly original style.

In the 1990s, with the change in the global strategic situation following the Soviet demise, the Hungarian government got rid of many military infrastructures, and Veszprem was on the list. Since then, the airport was turned into a short-lived base for commercial transport run by a private company, and as of 2020 it is at the center of a dispute, where the local municipalities are trying to get the land for other uses.

What you can see now reflects this state of things – trucks coming and going everywhere between the old buildings of the former airbase, with some demolition work being carried out and some gigantic commercial storage being built close by. The air-side of the airport appears basically dead, with no flights coming or going, not even small private aircraft operating around it. However, a control tower is still on site, so technically speaking the airport appears to be open for operations.

The place deserves a visit especially for getting a glimpse of the large structure of the maintenance hangars. From the outside, they can be spotted from a distance thanks to their tall curved rooftops.

The hangars have been divided internally in smaller spaces at some point. Getting access is possible in some of them, by the sight is rather desolating since the roof has mostly collapsed, and vegetation is taking over wildly inside.

Towards the airport you can spot more technical buildings, surrounding a wide apron. These technical buildings are apparently from a later era. The metal doors of the big curved hangars are such that getting larger helicopters in and out would not be possible. Maybe they were actually sized for the smaller aircraft of WWII, and their use was somewhat changed in a later time.

Between the hangars and the runway, you can find an impressive number of smaller maintenance buildings and garages, likely for trucks.

In some of them, a few signs in Russian can still be found.

Open air as well as indoor platforms for truck servicing are also there in a number.

Going even further towards the runway – and very close to it – you may find a light, partly wooden construction, with extensive remains of writings in Hungarian, including boards and stuff related to air operations. Here you see also some ‘modern’ writing in English. This is probably a kind o clubhouse of a local flying school from more recent years, likely the 1990s or later.

Looking at the satellite map of Veszprem airbase, you will notice a number of buildings put like spokes on a wheel. These were probably part of the original flight academy. These are today in a very bad shape, totally emptied and waiting for demolition. You can still appreciate the sober, yet stylish construction typical of the late 1930s, with some elements in common with Berlin Tempelhof (see this post).

‘Pravda’ paper was used for gluing the wallpaper in most Soviet bases, and Veszprem is no exception!

Farther away from the runway, you can easily spot massive buildings from Soviet times, like those you could find in Pripyat (see this post), and almost in every larger city of the former USSR.

Further buildings feature a rather peculiar style, with stone decoration you would not expect in military buildings. The fantasy of such decoration is not in support of a Soviet make, so these buildings might be from an older era too.

Getting there & Moving around

As said, this former airbase is technically an active airport, so the area of the runway is likely not safe to go. Yet the level of security is close to null, and you would likely be able to invade the air side before being stopped. However, no aircraft was spotted for the whole length of a multiple hour visit.

The older buildings, including the hangars, as well as the more modern housing from Soviet times, are in a really bad shape, and mostly dilapidated by looters and spoiled by writers. The more modern truck garages and the buildings closer to the runway are in a better shape.

Access by car from the south-western corner is not prohibited, so this may be a good way to get close to the buildings. Large parking opportunities, as the place is mostly unguarded and uninhabited. Just be sure not to interfere with local businesses. Even when spotting your car, the locals will not care about you (this was my case at least), so the place can be visited without much tension. However, for historians this place has not much left in store, and it may be visited mostly for the massive ensemble than for specific highlights.

Tokol Airbase

The former airbase in Tokol is today an active airport. The base used to be a major Soviet asset in the Cold War years, and home to a number of squadrons from the Soviet Air Force and the Soviet Army as well, operating everything ranging from helicopters up in size to transport aircraft. Its extensive premises have been divided, and the state is basically renting most of the hardware – including the former aircraft shelters and aprons – and land to a number of private enterprises, either connected with aviation or not.

The runway is still active for smaller general aviation aircraft, as you can see from the pictures. The place is really a suggestive scenario for pleasure flights, especially for history-fond pilots!

During our visit we had the chance to access some of the largest air shelters, built in the 1980s for aircraft the size of a MiG-29. There are at least five of them, along with more common and smaller ones.

Designed for the case of a scramble, these shelters allowed an aircraft to start its engines inside.

To this aim, the back of the shelter is not closed, but it features a large exhaust deflector tunnel, bent towards the side of the hangar, with a metal door closing it when not in use.

The front gate of the shelter is blast proof, an its thickness is actually really amazing!

The hangar we accesses shelters a couple of nice historic aircraft today. Traces of writings in Russian are a testimony of the previous owners.

Several abandoned buildings, including a rather large one with a small control tower, possibly from an older era – judging from the style similar to some German airfields from Hitler’s times (see this post).

One of the smaller shelters hosts another private enterprise, operating a unique airworthy Aero L-29 trainer from Soviet times. The same hangars offers a rich collection of Soviet signs on the walls.

Tokol features a number of older control towers – the reason is hard to guess…

Climbing one of them, we could get a very good view of the western part of the airfield, with many shelters around. Rather unexpectedly, the tower features an official writing in Chinese – maybe for potential Chinese customers?

Away from the runway, the airbase unfolds with a network of service roads and a number of buildings from Soviet times, today still in a very good shape, albeit shrouded by vegetation.

Getting there & Moving around

Tokol is an active airport, fenced and guarded. Getting in is basically not possible, unless you have a valid reason to enter. We had the chance to get in thanks to the invitation of the owner of the historical Aero L-29 mentioned above, who is also the tenant of the corresponding old aircraft shelter.

Basalt-Type Nuclear Storage on Kunmadaras Airbase

Kunmadaras used to be a major Soviet attack base in Hungary. The place was base for Sukhoi Su-17, Su-24 and MiG-27. This clearly justifies the construction of a Bazalt type storage, for aircraft-dropped nuclear weapons.

As the base is home to some residual, non-military activity and consequently at least lightly guarded, it may be interesting to concentrate on the most unusual nuclear bunker, located in an isolated spot, some .75 miles north of the runway and far from the most active areas.

The road connecting the airport to the bunker, detached in a fashion similar to other Soviet bases (see here and here for more examples), is today completely invaded by vegetation, leaving only a narrow passage to get access to the wide apron where the bunker entrance is located.

A loading platform for trucks can be spotted to the side of the shelter, ahead of the apron.

The six pillars, once covered with a roof and holding a crane for loading operations, are still prominently in place.

The entrance to the bunker is partly hidden by overgrown vegetation. The external curved tight door is gone, similar to the square shaped one deflecting side-ward and creating an airlock by the main entrance. Access is henceforth very easy.

To the side of the entrance corridor, the technical rooms have been spoiled of any hardware, yet the original paint is still in place, as well as writing in Russian. The metal staircase leading to the rooms for the air conditioning plant on the upper floor has been taken away, making the upper level inaccessible. Air conditioning was pivotal in nuclear storage bunkers, due to the need to store the warheads in specific temperature and humidity conditions.

Going further in, you finally get close to the gate of the storage chamber. The two halves of the massive curved tight door once closing the chamber have been taken from their posts and left on the ground. This provides a glimpse of the monster size of these blast-proof doors.

The chamber has turned very humid, and is totally dark. With the help of a torchlight or a camera flash, you can see the walls are still largely covered in their original coat, with painted frames and numbers possibly marking the position of fire extinguishers.

Electric line or pipeline holders painted in green can be found on one side. Also the pavement features a peculiar colored pattern, painted on a kind of linoleum, today covered in dust and dirt.

The concrete wall to the back of the chamber has been torn down, and some stones and land have come into the chamber. Bazalt type bunkers had only one main gate to the front.

Back out, to the north of the hangar, traces of the original barbed wire can be found in the impenetrable vegetation.

Going north from the shelter, pointing away from the base, you can get a distant view of conspicuous housing for the troops and their families – today completely abandoned.

Getting there and Moving around

As said, the main gate east of the base is guarded, as private companies have taken over part of the premises. However, the nuclear bunker is located north of the airfield, at a safe distance from the former airbase and the businesses going on there today. You may reach close to the base by car along an unpaved road used by local farmers, going parallel to the northern side of the base, keeping about 1 mile from it. This is not suitable for city cars though, so maybe you can stop when you feel appropriate, and go by foot.

To access the bunker area from the road (i.e. from north), you need to go through a field of turn-flowers. My advice is to go along the side of the bunker area to the south of it, and taking the old connection road going from the base to the bunker pointing north – trying to penetrate the area directly from north is made extremely difficult, due to the incredibly dense vegetation.

The area of the bunker is totally abandoned, so you can take your time when visiting the place.

Kalocsa Airfield & Anti-Aircraft Defense Area

Kalocsa airfield, located just northwest of the homonym village famous for the paprika business, was used by the Soviets as a helicopter base. Today, this relatively small airfield is very active with smaller general aviation flights and flight school activities, henceforth it cannot be toured freely.

However, to the northwestern corner, you may easily access the area of a former SAM base, likely put here to defend the airfield from air raids. The area features a number of small almost-circular embankments, with concrete platform at the center. This is where the missile would stand. Looking closely, you may see the concrete ducts for cables and pipes connecting the control trailer to each missile.

The area of the embankments is connected to an abandoned command building via a narrow paved road. To the western side of the building, traces of a small monument can be found.

Just south of the command building, a hangar made in 1970 – as the sign clearly says – is today used as a stable.

Getting there & Moving around

Access to the northwestern corner of the airfield is easy moving by car along an unpaved road going along the western side of the airport, and accessible from a public road running south of it. The area of the missiles is formally on the airport, so you should be careful not to interfere with any activity. More importantly, you are likely on a farmer’s land, so enter at your own risk.

Heviz Airport (formerly Sarmellek Airbase) and Granit-Type Bunker

What is today a small civil airport, surrounded by an array of rotting buildings, used to be a prominent Soviet air base, reportedly operating even the MiG-29 type in its heyday.

Being an active commercial airport, access to the air-side is not possible. Yet the premises of today’s airport are more modest in size than those of the original airbase. As a result, you may get access to a part of the former airbase without interfering with airport operations.

Many local businesses have taken over most of the former shelters for fighter aircraft.

Significant houses and garages, in the shabby pure-Soviet style, are now abandoned, and make for a creepy sight.

Going along a former service road, taking south from the control tower, you end up in the land of a farmer. Where the road ends, you can easily spot beyond the fence marking the current perimeter of the airport, the entrance and the typical round shape of a Granit bunker. The original metal door typical to this type is missing, or maybe it was never installed.

As said, Granit bunkers could be used for a variety of purposes, including storing command and control facilities, or as communication bunkers. The fact that the CIA listed this site as a nuclear depot may be also due to the fact that the Granit bunker made the place ‘nuclear-ready’.

Getting there & Moving around

As said, this is a commercial airport. The entrance to the former airbase gives access to the control tower as well as the small modern terminal area – a new building to the northeast of the runway. As said, the Granit bunker can be reached by taking the service road from the control tower to the south. This is surrounded by desolating dumps and half-demolished buildings. While technically out from the active airport area, you are still likely moving on private land, so enter at your own risk.

At the end of WWII, the territory of conquered Germany was split in four sectors by the then-Allies – the US, Great Britain, France and the USSR. A substantial part to the north-east of the country fell in Stalin’s hands. A few years later, following a re-organization of all territories occupied by the Red Army during WWII, the Soviet part of Germany was turned into a communist-led state known as German Democratic Republic (‘GDR’, or ‘DDR’ in German language).

Especially from a military standpoint, similar to Poland, and later Hungary and Czechoslovakia, this produced a kind of cohabitation. As a matter of fact, besides clearly backing the communist dictatorship in occupied countries, the Soviets did not quit at all from newly acquired western territories. On the contrary, thanks to the position on a potential war front had the Cold War turned hot, the westernmost Soviet-controlled countries – with the GDR on top – were stuffed with Soviet military bases, and hundreds of thousands troops. These shared the map with the national military, which in the GDR were known as NVA (an acronym standing for the German equivalent of ‘National People’s Army’).

The national and Soviet forces often took control of separated military facilities, and while operating in a coordinated fashion, they were substantially different entities. As said, this was typical to many Soviet-controlled countries. Yet especially on the relatively small East German territory, of high strategic value thanks to the shared border with the West, the total number of tank bases, training academies, air bases, missile bases, nuclear depots, shooting ranges, etc., reached an unrivaled world’s peak, when compared to the population or the size of the country.

Following the crisis leading to the end of the GDR in 1989, and the collapse of the USSR roughly two years later, all these military assets turned surplus. The German reunification, and the disappearance of a significant military opponent in the close vicinity of the border, triggered a rationalization of military resources in Germany. Most of the NVA bases were closed. The Soviet-controlled installations were evacuated more slowly – it took until 1994 to bring back to their Russian homeland the thousands of troops and tonnes of material stationed in Germany. Once returned to Germany, also most of these bases were deactivated and closed.

Since then, the fate of these former military facilities in Germany has been in the hands of local governments or national initiatives. As a matter of fact, following a few decades spent as ghost bases – a real paradise for urbex explorers! – most air bases have been converted into solar power plants. Some of them have retained an airport status, either with a very reduced runway, or in some cases being turned into full-scale commercial airports. There are exceptions too, as some are still at least partly abandoned, and while invaded by vegetation, they are still totally recognizable especially from above. Other bases, like tank bases or nuclear depots, while mostly earmarked for demolition, have been comparatively better ‘preserved’ – at least, they have been attacked by the state more slowly, so there is still much to see there.

You can find on this website several reports about quite a few of these military bases in the former GDR – especially airbases – from a ‘ground perspective’. Sometimes, it is difficult to appreciate the size, shape, as well as their concentration over the former GDR territory. In order to better show these aspects, now here you have a portrait of many of these bases from the air!

The photographs in the present post are from a single, two-hours flight on a Cessna 172 single-prop aircraft. The flight took place in July 2019. As you can see from the locations pinpointed on the map below, on our route we met not less than 15 former (or still active) military items. And this is just a short trip mostly in southern Brandenburg – i.e. the region immediately south of Berlin.

This report is a complement to other chapters on this site, yet it is especially interesting on its own, as a comprehensive bundle of aerial pics on this subject is not easy to find!

Sights

Points of interest are listed following the flight plan, which was flown roughly as on the map, in a counter-clockwise direction, starting from Reinsdorf Airfield.

Soviet Nuclear Bunker Stolzenhain

This one-of-a-kind facility – there were actually two such depots, but one is today demolished and inaccessible – used to be a major storage for nuclear weapons for the Soviet Western Group of Forces, which included all Soviet troops stationed in the GDR.

The bunker is today closed, but it apparently lies on private land, hence sparing it from being turned into something else (or simply flattened) by the local government. You can see a dedicated report in this chapter.

Vegetation has grown wild in the area, but from above you can clearly spot the rectangular perimeter of the external concrete wall. From north to south, an internal road crossed the rectangle in the middle.

The bunkers are half-interred, hence from above you can barely spot the entrances. These are aligned along a service road arranged in a hexagonal shape.

To the south of the bunker area, you can spot a former group of barracks and an access road heading west. Construction and demolition works are taking place in this area.

Control and Reporting Center Schönewalde

This is an active military installation, and actually quite an advanced one. It is tasked with monitoring the air operations over a large part of the airspace over Germany.

The origin of this half-interred technical installation can be traced to the 1970s, when the site was activated under responsibility of the NVA. Following the end of communist rule and after German reunification, unlike many others this site was not demolished, but instead it was developed further, and pressed into the defense chain of NATO since the mid-1990s.

You can see many half-interred warehouses, garages for trucks, a smaller radar antenna to the west of the complex, close to a helipad.

There is also a larger antenna to the northeastern corner of the CRC.

Holzdorf Air Base

This large airport used to be an airbase of the NVA. It is one of the few airports from the Cold War in the GDR which were turned into a full-scale modern airport. Today it is a base of the Bundeswehr, i.e. the German military.

As we approached from north, you can spot first typical large communist buildings, forming a citadel which is likely still today hosting troops and their families. There is also reportedly a flight academy for helicopters in this complex, north of the airport.

The airport features large hangars for military helicopters to the northwest of the runway.

A rather old-styled control tower can be seen to the south of the runway.

Falkenberg Air Base

We reached the southernmost point on our flight with the former Soviet base in Falkenberg. This old base dating to the 1930s went on to be developed into a Soviet base home to fighter aircraft, MiG-23 and later MiG-29. Close to the airfield, there used to be a SAM missile battery (to the west of the runway).

Approaching from the north-west, you can notice a small ghost town and a large technical area, with what appear to be big unreinforced maintenance hangars, today used for something else by local companies.

The airport is today dedicated to light aviation activities. The runway has been shortened, and sadly large portions of the original airfield have been covered with solar cells.

Most interestingly, in the trees to the northwest of the runway, you can spot four unfinished aircraft shelters – possibly of the type AU-16, which could host both the MiG-23 and MiG-29. They look like short concrete tunnels. They should have been covered with land, but works were interrupted in 1990.

More aircraft shelters – completed – can be found to the east of the field, today used for storage, as it is often the case.

Finsterwalde Air Base

This installation was operative since WWII, when the large hangars and control tower still in place to the south of the apron were built. The base went on serving as a Soviet base, hosting fighters and fighter-bombers of many kinds along its illustrious history. A visit to this site, with its nuclear depot, can be found in this chapter.

Approaching from the southwest, we flew over the nuclear storage bunker, made for nuclear warheads to supply aircraft operating from here. The columns once holding the crane to lift the warheads can be clearly spotted.

There is also a group of Soviet-style houses for the families of the troops. Apparently somebody is still living there!

The base was enlarged with reinforced shelters to the north and southwest of the runway. The large hangars to the south are still in use with local companies, some of course connected with flight operations – this airport is still active for general aviation operations.

Enroute to the next waypoint, we flew over a natural preserve, which offered some quite spectacular sights.

Alteno-Luckwalde Air Base

This airfield north of Finsterwalde was a reserve airport of the East German NVA. While never developed to the extent of primary airfields, it was among the few reserve air bases to receive an asphalt runway.

Today, the view is rather desolating – the airfield has been totally covered with solar cells.

Brand-Briesen Air Base

This WWII base was selected for quick and substantial improvement since the early Cold War years, and went on to be one of the most developed Soviet air bases in the former GDR. In the beginning it hosted Ilyushin Il-28 bombers, but in the jet age it was home to a number of different squadrons and aircraft types. You can find the results of the exploration of a part of this base in this chapter.

Approaching from the south, you first spot an immense hangar, conceived at the turning of the century for commercial airships, and later turned into a water park – Tropical Island.

 

But more interestingly, to the south of the airfield – unusually far from it, actually – you can find a depot for nuclear weapons, to supply the aircraft operating from the base. Similar to Finsterwalde, the pillars once holding the crane for lifting the warheads can be clearly seen.

Still to the south of the airfield, the local citadel for the troops is today an interesting ghost town.

As you may notice, the airfield is today closed, and has been largely converted into a recreation park. Incredibly, they decided to build an array of small houses on the former premises of the airport, and in close proximity to the monster airship hangar.

Yet some relics from the past function of the air base are to be found scattered around. These include aircraft shelters, and more rare engine testing facilities – V-shaped concrete walls emerging from the grass nearby some of the shelters.

Kleinköris Air Base

This airbase was activated in the late 1960s as a reserve airfield for the East German NVA. It was used for exercises, and as a home base for helicopters of the Volkspolizei, i.e. the police of the GDR. After deactivation, it was used as a military storage for a while, and finally closed.

The appearance, perfectly evident from the air, is rather unusual – it features a long grassy runway, with concrete taxiways at the ends. To the reports from the time, this is the original configuration of the airbase. Luckily, it is basically still intact.

Wünsdorf

The name of this small town will be forever linked to the two military high commands which were headquartered on its premises – Hitler’s OKW first, and the command of the Soviet Western Group of Forces for the full span of the Cold War. You can find a dedicated chapter here.

From above, you can get a nice view of the extension and shape of this military town, as well as good portraits of some of the highlights in it. Approaching from the southeast, you first meet the most famous building in Wünsdorf, the officers’ house. This majestic building dates from the early 20th century. It knew an extensive renovation during the Cold War years, as an officers’ club for the Soviet Red Army.

This huge building features a statue of Lenin on one side. In the wings to the back, you can find a swimming pool and a theater. The round building with a mural is a late Soviet addition, and once hosted a circular panorama painting.

The high command occupied the buildings north of the officers’ club, today converted into something else.

Another highlight of Wünsdorf are the many bunkers. These include the Maybach bunkers from Hitler’s era, once hosting the OKW. These were designed for deception as living houses, but could withstand aerial bombardment. They were blown by the Soviet, with only partial success. The Zeppelin bunkers, like cusped concrete towers, were designed to resist bombardment, by deviating air-dropped bombs falling from above along the sidewalls and down to the ground nearby.

Soviet bunkers were located very close to the array of Maybach bunkers. They are largely interred, and from above you can see some concrete tunnels in the trees.

The railway line and station is an historical track from the time. The Wünsdorf-Moscow line operated in both ways on a daily basis. The service was suspended only in 1994, at the very end of the withdrawal of the last occupation troops to Russia – for many, the symbolic end of Soviet occupation.

The buildings for those stationed in Wünsdorf and their families were really many. Today this town, having lost its original core business, is largely uninhabited.

Sperenberg Air Base

Not far from Wünsdorf, you can find the former Soviet air base of Sperenberg. This immense transport base used to be a major logistic base for the Soviets, which operated from here with their monster cargo planes. More on this base can be found in this chapter.

Approaching from the east, you first meet the buildings for the troops, to the east of the airport and close to the village.

An aerial view allows to clearly capture the shape of the base, with two large parallel taxiways with a huge array of parking bays for transport aircraft, and a long runway – still basically intact! – to the south.

A large hangar with an inscription in Russian can be found to the east, whereas a small terminal building can be spotted ahead of a large apron to the west.

Today the airport is closed, but rumors have surfaced more than once concerning its evaluation as a third airport for Berlin. This may justify its missed conversion into another desolating field of solar cells.

Kummersdorf Military Laboratory

A bit of an outsider here, Kummersdorf holds a very relevant place in the history of war technique thanks to pre-Soviet activity. In the late 1920s the Germans established here an experimental laboratory especially dedicated to novel weapons. It can be said that western rocketry was born here, since the group of Walther Dornberger, later joined by Wernher von Braun, started operations on liquid-propelled rockets in this lab.

Activities later moved to somewhere else, and finally landed in Peenemünde – see this dedicated chapter.

The laboratory in Kummersdorf was used also during WWII to test captured material, especially enemy tanks. Following the end of WWII, the Soviets took over the facility, but turned it into a more standard military base.

The red barracks in typical German style can be clearly seen from above. Most of the post-WWII depots are falling apart, but the area is really huge.

Forst Zinna Military Base

This base is located to the northeast of Jüterbog-Altes Lager, a huge Imperial, Nazi and later Soviet military complex, including two shooting ranges, a few airfields, an academy and many barracks.

Forst Zinna base was operative in the years of the Third Reich, named after Adolf Hitler himself. It went on to become a large base for the artillery groups training in the nearby shooting ranges. A dedicated chapter can be found here.

From above, it is clear that demolition works are slowly wiping out the base. Yet there is much housing left to visit. Typical German buildings share the area with shabby Soviet ‘socialist housing’. A bridge passing over a major road and railway track going to Berlin links the base to the shooting range north of it.

Altes Lager Shooting Range and Barracks

The shooting range north of Forst Zinna is pointed with concrete control towers. The area is very extensive, and quite more convenient to explore from above!

Closer to Altes Lager, many barracks can be seen aligned along a major road. From the style, these appear to be from an older time than the Soviet occupation years.

Jüterbog-Altes Lager Training Academy

This pretty unique piece of architecture dates from the years of the Führer, and used to be an academy for air force technicians. It was later turned into a military academy for Soviet staff, and a KGB office was reportedly active here too. A report can be found in this chapter.

From above you can better capture the plant of the complex. The half-circle to the north hosted a big theater in the basement.

Most strikingly, in the western part of the complex you can see sporting facilities which have been completely refurbished, and are actually in use. These include a football field and some tennis courts. There is also a pool, but this has not been refurbished.

Jüterbog-Niedergörsdorf Air Base

This large air base was jointly operated by the NVA and Soviet air force. You can find a report in this chapter.

Approaching from the northwest you can see aircraft shelters, whereas to the northeast you find an array of large maintenance hangars. These have been turned into something else, including a test driving facility, which chopped part of the original apron.

To the south of the runway, the base used to feature a large number of parking bays for helicopters. The runway has not been physically cut, albeit a central section of the original concrete has been taken away. Air operations today are apparently limited to ultralights and trikes.

A menacing army of solar cells is attacking the perimeter of the base from the east! An unmissable sight next to this base (to the east) is a former aircraft shelter turned into a private collection of Soviet memorabilia – Shelter Albrecht (covered in this post).

Enroute to the next waypoint, you can clearly spot from the air a military hospital complex (see this chapter) – rather famous among urbex fanatics… – and other service buildings.

Jüterbog-Damm Air Base

This base dates to the years of the German Empire. It was forcibly demilitarized after WWI, but strongly developed in the years of the Third Reich, with the construction of large concrete hangars and service facilities, and a grassy airstrip good for fighter planes of the era.

Following conquer by Soviet forces, the airbase was partly dismantled, but at some point a SAM battery appeared on this site.

Today you can appreciate the size and special shape of the concrete hangars, a true engineering masterpiece from pre-WWII years.

Landing in Reinsdorf

Finally, you can see here a vid of the perfect approach and landing into the touristic airfield of Reinsdorf, about two hours after take-off!

Practical Notes

This flight was carried out from Reinsdorf Airfield (ICAO: EDOD), located about 10 miles southeast of Jüterbog, the most sizable town in the neighborhood. The airfield is roughly 1 hour driving south of downtown Berlin, very easy to reach with a car.

The flight would have not been possible without the help of a fantastic couple, Mrs. Kolditz and her husband, who own a nice French-built Cessna 172 from the mid-1960s, D-EBLD, portrayed here.

There are some features making this very aircraft ideal for aerial pictures. Besides the high-wing configuration, this exemplar features a side window which can be completely opened, allowing for an unobstructed view of the scenery below.

The man is a former NVA pilot, something that must have played a part in him accepting to set up this very unusual flight plan! His great ability as a pilot helped much in having the aircraft in the right position to take the desired aerial pictures.

Thanks to the availability of the Kolditz family, setting up the flight was an easy task, even operating from abroad and through much Google-translation!

Another key-element in this adventure was Federico, a friend of mine sharing my passion for flying, who lives in Berlin, and played an essential part in co-financing the flight and translating between me and the pilot, as – perhaps incredibly, considering the content of this website… – I don’t speak German.

If you are interested in sightseeing flights south of Berlin, I suggest inquiring with the folks at Reinsdorf, a very active airfield with many facilities for touristic and pleasure flights. Website here.

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.
