Soviet Nuclear Bunkers in the Czech Republic

History – In brief

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

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

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

Soviet Nuclear Depots in Czechoslovakia

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

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

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

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

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

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

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

Sights

Javor 51 – The Atom Museum, Míšov

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and visiting

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

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

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

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

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

Javor 52 – Bělá pod Bezdězem

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

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

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

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

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

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

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

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

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

Getting there and moving around

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

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

Javor 50 – Bílina – Quick note

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

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

For war historians and urban explorers Wünsdorf does not need any further presentation – a central place in the military history of the 20th century, famous for the many abandoned military buildings, from stately headquarters to interred bunkers. The name of this small town appears even in the very modern and interesting Military Museum of Dresden, where it is easy to find an original sign – in double alphabet – from the time when Wünsdorf hosted the Soviet military headquarters in the communist German Democratic Republic.

This report is based on photographs I took in spring 2017 in Zossen and Wünsdorf during a customized visit to the place I arranged with a local guide. For visiting information scroll down to the bottom of the page.

History – in brief

The small town of Wünsdorf, about 15 miles south of Berlin, has a serious military tradition, dating back at least to the beginning of the 20th century. At that time a large military complex with many barracks was set up by the order of the German Kaiser Wilhelm II – a central player in WWI – in the neighbor town of Zossen.

To this ‘Belle Époque’ era belongs part of the housing still in place today, as well as some of the largest and most aesthetically pleasant buildings in town. Among them, a former training camp for athletes of the army, and some big command buildings.

Following the dawn of the Nazi era, the place gained further relevance, with the institution of the German Supreme Command of the Armed Forces, also known as ‘Oberkommando der Wehrmacht’, or ‘OKW’ in brief. This was presided by general Wilhelm Keitel for all the duration of WWII, and represented the ‘top of the pyramid’ in terms of military decisions, as general Keitel reported directly to Hitler.

The staff of the OKW could be accommodated in purpose-built bunkers here, designed to withstand severe air bombing action, as well as to be disguised as normal country houses from above. These were known as the ‘Maybach bunkers’.

Besides bunkers for housing military personnel, a large communication bunker, known as ‘Zeppelin bunker’, was built to the purpose of connecting the brain of all military operations with the various divisions scattered over Europe and fighting on more war fronts.

When WWII finally came to an end, the Soviets captured the region, and that was the onset of a full new chapter in the history of the town. The reference name ‘Zossen’ was dropped in favor of ‘Wünsdorf’. The area of the two villages was totally cut-off by a 17 km wall, guarded with a top security level. Inside, housing for around 40,000 staff was prepared in subsequent stages, adding many purely Soviet-style residential buildings to what was still in place from before and during the Nazi era.

The supreme command of all Soviet forces in the occupied territory of Germany – to become the German Democratic Republic, or ‘GDR’, in 1949 – was installed here. All four branches of the Soviet armed forces had their respective headquarters in a corresponding sector of the ‘prohibited citadel’, with inner walls dividing the four areas. These headquarters controlled more than 200,000 troops stationed in the GDR until the early Nineties.

The Soviets tried to blow up the Maybach bunkers, with some success, and also the Zeppelin bunker, with no success. They developed it into an nuclear-proof installation, and added two further bunkers, for controlling military operations – including all air patrolling ones – in real time over the territory of the GDR, and along the crucial border with the Federal Republic and the Western world. Similarly to WWII, once again Wünsdorf was the main stage of crucial decisions for the full span of the Cold War.

The year 1989 marked the beginning of the end for this military town, with the reunification of the GDR with the Federal Republic and the end of the Cold War. All Soviet forces stationed in Germany – about 500,000 people, including troops and their families -, soon to become Russian forces in 1993 with the collapse of the communist regime in the USSR, began a well-coordinated retreat back to their mother Country, leaving Wünsdorf in September 1994.

Since then, the huge housing is largely uninhabited – the current population having dropped to about 4,000 – and the stately buildings built by the order of the Kaiser are deserted. Nonetheless, differently from other former military bases left to nature or converted into something else, the regional government of Brandenburg has formally taken over the property, which is not totally abandoned, nor in an irreversible state of disrepair, with the aim of selling it or transforming it into a museum.

Up to now, the place is still in the hands of the regional government, and specialized tours can be arranged with a local society of enthusiasts.

Sights

This site is really huge, with countless remains and interesting places to see. My visit took just about 5.5 hours, I think you would really need 1 day – and possibly more – to cover all features with enough time to both learn about the history and take good pictures of everything interesting! Here I will present a mainly pictorial description of the part of the complex I had the chance to visit this time. I think another day I will need to go back and complete the visit!

You may get an impression of the town from above, from this report based on aerial pictures taken during a dedicated flight over the region.

Officers’ House

This is probably the most famous non-bunker building in the complex. It dates back to the early 20th century – the place was the headquarter of a sports training ground established by the Kaiser’s army before WWI. In the Thirties, German athletes were trained here for the 1936 Olympic Games in Berlin. During WWII this became a command building for the OKW, while in Soviet times it was actually transformed into a house for higher ranking staff of the supreme Soviet command, with living rooms and entertainment facilities.

The main building faces an almost square park, where a huge statue of Lenin was installed and is still standing.

Inside the main building it is possible to find clear traces of the original ‘Belle Époque’ architecture.

The inside of the building was spoiled of all furniture – the Russians reportedly tried to sell everything to the German government when they left, but the offer gained little interest. Only little part of the furniture, clearly from the age of the Kaiser, can be still spotted. Among the highlights of the bottom floor, there are two murals, in a typically Soviet naïve style, and a sculptured wall. Somebody is trying to put together Soviet memorabilia in a small museum, but all presented stuff is not original from here.

On the first floor, a very interesting industry-themed mural and a 20-ft long curved view of Moscow can be found in a corridor. In a completely dark room on the same floor, where once a small memorial museum about the Great Patriotic War – WWII for the Russians – was standing, the retreating Russian forces left one of the few remaining written messages, concerned with the atrocities of the Nazi regime – for the guide this was possibly a subliminal memento for the German People… In the same totally dark room it is possible to find a big, finely sculptured wall.

To the back of the main building it is possible to find a modern addition by the Soviets, a cylindrical building once hosting a diorama of the battle of Berlin. The diorama was transferred in the village of Zhukovo, halfway between Kaluga and Moscow, in the westernmost part of Russia, when the Russians left.

The two wings to the back of the Officers’ House host two highlights of the show. In the southern wing it is possible to find an empty swimming pool, dating from the days when the place was a sports training ground, with little changes, which include the showers and the diving board, built by the Soviets. The construction technique was very good, and the pool was operated until 1993-94 reportedly with little updates.

In the northern wing it is possible to find a theatre. This is a bit creepy, for it is totally dark – electric power was cut off years ago – but everything, including the curtain over the stage, is in place like a performance was about to begin! The Soviet past of the place is clear here thanks to the decoration of the medallion over the stage, resembling the monument of the Soviet Soldier in Treptower Park, Berlin. In the roomy foyer it is possible to see the numbered hangers still in place!

The White House

Across the road from the Officers’ House it is possible to see another early 20th century building, used as a command building by the Soviets during the Cold War, and affectionately called ‘The White House’, both for its primary role in imparting orders and for the colonnade gracing the front façade. The building is inaccessible, and still property of the regional government.

Nearby, a former house for officers dating from before WWII is now operated as a local city hall.

Today, some of the many immigrants coming from Africa to Europe are being hosted in a building close to the White House by the German Government.

Soviet Railway Station, Bread Factory and Soviet Housing

Due to its great strategic relevance in the Cold War era, the prohibited town of Wünsdorf was daily connected two-ways with Moscow. The last train to Moscow left in September 1994. The railway station of Wünsdorf-Waldstadt today operates on a local railway, with trains mainly to and from downtown Berlin. The old Soviet terminal and some warehouses nearby have been abandoned and are in a state of total disrepair.

Close by the station, it is possible to find an abandoned and unattractive small factory with a tall chimney. This is where literally tons of bread were produced every single day since the Nazi era and up to 1994 – reaching 25 tons per day when the place was most crowded in Soviet times. The building was considered a strategic asset by the Nazi, who built it with a 60 cm reinforced concrete roof able to withstand air bombing.

Whilst not very crowded, today some houses from the early days in the village of Zossen have been nicely restored to their original conditions. Unfortunately, they still share the roadside with some abandoned or not refurbished Soviet buildings, keeping the typical ‘Soviet ghost’ aura alive in the town.

Maybach Bunkers

Two complexes of peculiar bunkers were built in the Thirties – Maybach I and II – for housing staff of the OKW. From the distance and from above, these half-interred bunkers had the appearance of large farm houses. In reality, they were designed to be bomb-proof, and when they were blown-up by the Soviets after WWII they did not collapse completely.

One of the two Maybach complexes is very close to the fenced area where the Soviets had their three interred bunkers.

Zeppelin Bunker

This communication bunker was built under the Nazi more than 60 feet deep into the terrain. It was made of layers of land and concrete, making it extremely durable and difficult to destroy. As a matter of fact, the Soviets tried to blow it up after the Potsdam conference in summer 1945, but they didn’t succeed at all. They decided to re-use it, sealing part of it to withstand a nuclear attack – including airlocks, reinforced doors, showers for decontamination, and sleeping quarters for troops trapped in by radioactive fallout. When leaving in the Nineties, Russian troops took home all technical rigs, stripping the bunker almost completely of any technical hardware.

Among the highlights in the Zeppelin bunker there are the sealed main entrance built by the Soviets and the decontamination facilities.

Going down it is possible to appreciate the size of the German design, with tens of rooms, long and roomy corridors and staircases. A small exhibition is dedicated to communication hardware from the Nazi and Soviet times. Copies of the Nazi schemes of the communication network from here to the Eastern front allow to understand the proportions of the system.

One of two long tunnels – the longest is about 600 ft! – was turned into a sleeping quarter for troops isolated in case of nuclear attack, and original berths are still visible today. Another corridor was so long it was used as a rifle range!

The bunker was powered by diesel engines – originally submarine engines under German ownership. These are gone today, but the smell of diesel fuel is still very marked in their room. It’s hard to imagine how noisy this place had to be! Some of the Soviet fuel tanks and air conditioning piping are still there, with original technical schemes.

A lift was added by the Soviets – it’s not working any more. On the bottom level there are water pumps and other supply systems. Normally this area cannot be toured, also due to water flooding problems.

In a small wing of the bunker it is possible to see the effect of the Soviet attempt to blow-up the bunker. The dynamics of the attempt are not clear – what explosive was used and where it was positioned. A pierce in the steel/concrete armored ceiling and a cracked reinforced concrete pillar are the only visible results. The size of the crater in the ceiling suggests much explosive was used, but the damage around is fairly limited and very localized. A feature of many military buildings occupied by the Soviets, signatures and graffitis in cyrillic alphabet can be found on some concrete walls of the bunker.

Soviet Half-Interred Bunkers

Really close to the entrance of the Zeppelin bunker, it is possible to find the way into two other less visible facilities.

One of them is a small communication bunker of simple construction. This is basically straight, with a round shaped cross-section. The corridor leading to the main part of the building is rather narrow and pointing down to the underground. The main part is much roomier, with curved steel frames making the walls and ceiling. This was used also as a training facility. This bunker was totally stripped by the retreating Russian troops.

The second bunker is much more articulated. It was codenamed ‘Nickel’, and the Soviet construction type is UK-20. This was a communication and control bunker for military operations, in particular for air operations. Even though this bunker was stripped similarly to the other two, some technical rigs and tons of paperwork can be spotted in the semi-dark environment of this installation.

Technical plants include the original water pumping system and several high voltage cabinets.

The room where the air control center was is lighted. It is very big, and copies of the original schemes help to understand how the setup was. Everything there was taken back to Russia by retreating Russian army.

Other interesting items include propaganda posters from Soviet times – they always look very exotic!

Garrison Museum & Red Army Museum

In the old pre-WWI stables two really unmissable small museums have been prepared. I would recommend visiting them after the site itself, to better understand the relevance and usefulness of the exhibition.

The first is centered on the history of the garrison in Zossen from the years when the barracks were built, and it documents the history of the Officers’ House and all other pre-Soviet buildings around. A focus is given also to the Nazi period, with many photographs and memorabilia. All panels are unfortunately in German only, but the pictures speak for themselves.

The second collection is dedicated to the Soviet period. Here you can find memorabilia from all stages of the Cold War era, including both museum items already preserved by the Soviets in a museum previously existing in Berlin-Karlshorst, but also everyday items and stuff from Wünsdorf.

Among the many panels, a small insight dedicated to the huge nuclear base in Vogelsang, covered in this other post of mine.

Headquarters of the Soviet Air Force

Besides the building of the society running the guided tours of the place, it is possible to find the abandoned headquarters of the Soviet Air Force. A modern statue of a pilot is standing ahead of an Asian restaurant, whereas the main building is inaccessible. A statue of Lenin – not easily visible from the street – can be found in the vegetation, ahead of the main façade. To the side of the building it is possible to find a typical Soviet memorial.

Much More…!

Among the other uncommon things you can find around in Wünsdorf, there are some Winkel-type air raid shelters, 19 of which were built in the Nazi period for military staff. Most of them were blown by the Soviets, and some of the 7 (?) remaining ones are preserved today.

Visiting

As reported, this ensemble is huge and well looked after. Technically speaking, it is not abandoned – at least the most interesting parts of it. Parts – like the Officers’ House – are awaiting for somebody to own them, parts are destined to remain tourist attractions – like the bunkers and museums. For these reasons, to make your visit practical and enjoyable, and for making the best of your time, I strongly suggest contacting a guide.

Actually the local society also in charge of the nice and interesting book selling activity, for which ‘Bücherstadt Wünsdorf’ – ‘Wünsdorf the Town of Books’ – is famous, runs guided tours on a regular schedule. Full information also in English from their website here. Besides the pre-scheduled tours, some longer special-themed tours can be booked in advance. If you are visiting – like me – from abroad, then I suggest taking contact with the guide before going there.

When I visited, I arranged with the guide a ‘double-tour’ in English just for me, asking to merge two of the tours offered with pre-booking. This was not a cheap alternative – I had to pay alone the price intended for two group tours, but all in all that was worth the financial effort! – but above all I must say I regret not having had more time!

The guide is nice and extremely knowledgeable, he speaks a perfect English and Russian as well. He knows anything from the history of the place, including interesting anecdotes and technical notions. He will take you to all places of interest with a minivan, and of course he will give you all the time for taking pictures, including some with a tripod in especially dark conditions – he has two portable lights for helping in the task! So the guided tour will not be boring at all.

After that, you may like to go back to have a look to the exterior of some buildings you had not the time to check out during the guided visit.

The towns of Wünsdorf and Zossen are basically a single entity, but possibly not on your nav. In case you get confused when driving to the building where you should meet the guide, just follow the signs for the book selling activities – the building is the same.

I mentioned there is a railway station, and of course you may choose to come in by train and move by bicycle – walking would be too time consuming in my view, due to the distance between points of interests. Coming by car is also very practical if you are not moving by train on your trip, and there is room for parking almost everywhere.
