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).

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.

Hitler’s Mystery Mega-Structures in Central Europe

During the last two years of WWII, the Wehrmacht of Nazi Germany was slowly retreating from the eastern front, pushed back by the mighty blows of the Red Army. The bombing runs carried out by the western Allies from airfields in Britain were systematically hitting most urban centers in mainland Germany and over the territory occupied by the Nazis. It is hard to imagine, but it was in the year 1944, when the destiny of Germany was almost sealed, that industrial production in Hitler’s Third Reich reached an all-time record.

At that time the Germans were desperately short of fuel, raw materials and troops, and their production efforts would not spare them from a complete defeat in 1945. Yet it was in the last stages of the war that some of the most ambitious industrial facilities were designed, built and in some cases made operative before the end of the war.

The driver of the design was in most cases the need to move production lines to secluded and well protected areas, difficult to spot and to destroy through air bombing. As a result, these sites were placed far from urban centers. They were also designed to withstand bombing, by putting them underground, or building them with substantial reinforcement, making large use of one of Nazi Germany’s favorite materials – reinforced concrete.

In this chapter two major sites of this kind are described. One is in southwestern Poland, a region which had been part of the German Empire for long before WWII. The second is in eastern Bayern, today one of Federal Germany’s most prosperous states, close to the border with the Czech Republic. Photographs were taken in late summer 2018.

Project ‘Riese’, Poland

Construction around this cluster of underground sites started in late 1943, and reportedly lasted until the closing stages of WWII, just days before the Soviets entered the region. The name ‘Riese’ means ‘giant’ in German, and it is surely well suited for this complex, which while far from finished is really striking in size. It was actually composed of at least six major construction sites, which in the intention of their designers should have been developed deeper in the mountains, until a link could be established between them forming a formidable network of tunnels and large halls.

Besides the size and historical meaning of these sites, what makes project ‘Riese’ so fascinating is also the actual purpose of this incredible complex is far from established. Three major theories exist in this respect. The complex might have been intended to be an underground industrial city, a kind of Noah’s Ark for the ‘superior race’ embodied by the top-ranking military and governmental staff of the Reich, or a gigantic secret laboratory for innovative technologies.

What is sure is that the construction was carried out by forced labor, mainly by prisoners of Gross-Rosen concentration camp, just a few miles north of the complex. For the scope, the Nazis created a number of satellite camps next to the entrance of the  construction sites. Rather incredibly, only very scant traces of the project remain in the written records of key figures of Nazi Germany – Albert Speer’s personal diary notably reports some millions marks allocated for project ‘Riese’, and at some point after the war he cited the item resulting from the completion of the construction works, whatever its purpose, as sized to be capable of hosting some tens of thousands people.

Today, six construction sites have been discovered, of which two – Osowka and Rzeczka, the most conspicuous – have been opened to the public, whereas the other are visitable basically for speleologists only.

Osowka

The first visitable site is in the town of Osowka. This site is composed of two parts, one underground with access from the side of a hill, the other close to the top of the same hill.

The underground part can be visited only with a guide. The plant of the completed construction features two accesses, and you will be driven in using the first and out using the other. Between the entrances, the site is mainly composed of an array of parallel tunnels pointing towards the mountain, connected by long halls.

Close to the entrance you can spot a concrete guardhouse with loopholes for machine guns. Some wooden structures like in a mine have been put in place to give an idea of the appearance of the working technique at the time of construction.

Most tunnels have been dug but not reinforced with concrete walls, whereas others are almost complete, showing a peculiar two-level design. The lower level features a smaller section, and the top one a taller, round shaped section.

A feature of the ‘Riese’ complex is a special technique for building the inner concrete coat of the rocky tunnels, producing the distinctive ‘church-ceiling-like’ appearance of some of the halls, with a round shape and frames close to one another.

The Osowka site features also a collection of smaller artifacts, collected from the ground and dating from the construction years, i.e. from late WWII.

Life-size silhouettes of some WWII tanks are on display, to show how the size of these items was totally compatible with the size of the tunnels, in support of a potential use of the site for weapon manufacture.

The outside part, which can be accessed freely, is the most mysterious. At the base of the trail leading uphill you can spot a strange concrete platform, with provision for – possibly – interred pipelines.

Close to the top of the hill you can find a huge concrete platform, with an apparently chaotic ensemble of slots, pipes, handles, stairs and pools. This item has been deemed close in shape to the base of a service building for the valves and pipelines of a power-plant. Theories have flourished in support of the use of this item as a prototype control system for a nuclear power-plant.

The nuclear program of the Nazis, which indeed existed and is even documented to some extent, is shrouded in mystery for what concerns the actual findings obtained during the war. These dark spots are also due to the destruction of most of the hardware connected with the program everywhere in Germany, and with the inherent secret nature of the program itself. No evidence exists of the Osowka site in the public papers about the nuclear studies of the Reich, so the true purpose of this object is likely to remain an unsolved riddle.

Close by this platform, you can find an original concrete building, part of the same construction plan. It is pretty long, with large windows, and likely intended for troops or technical staff.

Rzeczka

Compared to Osowka, this site is more centered on the inside part. Again, there are two entrances, close by a creek on the side of a hill, providing access to a network of tunnels. Similar to Osowka, close by the entrance you can find guard-houses in concrete. These were built soon, possibly for keeping a watch on the forced workers.

The construction works in Rzeczka were less advanced than those in Osowka. Yet thanks to the lack of the concrete coat, you can appreciate the size of the tunnels, some of which are really tall.

There are small collections of artifacts found in the tunnels, and an original concrete room offers a description of all discovered sites of the ‘Riese’ project.

A 1:1 copy of a V-1 German flying bomb has been placed in one of the tunnels, to show the compatibility of the size of this weapon with the tunnel. Such weapons were reportedly assembled in underground facilities elsewhere in Germany.

Visiting is again possible only with a guide. Some multi-media experiences with sounds, lights and voices are included in the tour, but these are not so impressive for those who don’t understand Polish.

On the outside, you can spot some relics from construction years, including trolleys, and concrete slabs watermarked with symbols of the local construction companies tasked with the practical realization of the site. There is also a copy of a V-2 rocket, operative in the last months of WWII but little effective in changing the fate of Nazi Germany.

Getting there and moving around

As pointed out, the sites connected with project ‘Riese’ are many, but most of them are not visitable unless to specialists and with the help of a speleologist. On the other hand, the two sites of Osowka and Rzeczka are professionally operated as primary tourist attractions. The distance from these two sites is about 20 minutes by car, so you can surely arrange the tour of both sites on the same day, with much spare time in your daily schedule.

At Osowka you can find a large parking and a fully equipped visitor center, where you can book a guided tour, or join a departing one – the only way to get inside. Please note that the number of people admitted on each tour is relatively small, so I would suggest booking at least one day in advance through their website (partly also in English) to be sure to get a place at the time you like. They offer several different tours. The most complete include a visit to a part of the underground site which can only be accessed by boat. This is given only on some days by reservation, and only for groups. The standard tour of the inside is offered several times a day.

The guided may turn out really boring, cause you are provided an audio-guide in English with explanations lasting a couple of minutes for each of the circa ten stops, in face of the Polish-speaking guide talking about 5 minutes per site. You may try to spend your spare time taking good pictures, but even though groups are relatively small, they tend to obstruct the view inside, leaving poor chances for acceptable shots. Furthermore, lighting is not very good, so a tripod would be recommended, except you don’t have the time and chance for undisturbed long poses. Therefore, if you are interested in top-level pictures, you would better arrange a dedicated tour out of the normal touristic offer. Otherwise, you’d better go prepared to a difficult visit.

The outside part of the site is less frequented and more rewarding. It can be reached in about ten minutes following a pretty steep, unpaved trail in the trees. This part is unfenced and unguarded.

The Rzeczka site has only an inside part, which can be visited only on a guided tour. You can join one of the frequent tours they provide even without reservation. There is a small visitor center and plenty of parking space. Similar to Osowka, the guide will speak in Polish, and you are provided an audio-guide in English. The visit lasts less than in the case of Osowka, and the audio-guide explanations are more proportionate to the speech of the Polish-speaking guide, making for a more enjoyable visit. The multi-media experiences are of little relevance for non Polish-speaking people. Outside you can find also some panels with explanations on the history of the site in both Polish and English. Website with some info in English here.

The tunnels in Rzeczka are poorly lighted too, so photographing will be difficult unless with a tripod, but the conditions are not very favorable for operating with a tripod – many people around and short times between stops along the tour.

‘Weingut I’ Aviation Industry Complex, Germany

The giant complex known as ‘Weingut I’, the original codename attributed by the Nazi staff at the time of its design and construction, is the direct result of a plan to relocate all major industrial production lines of the Reich to protected areas, far from the line of the front and from any major urban center. In this particular case, the new factory was intended to shelter the production line of the new Junkers Jumo 004 jet engines for the ‘Schwalbe’ – also known as Messerschmitt Me-262, this was the first jet fighter in the world to be pushed into service, back in 1944.

The huge factory was designed based on a basic module made of a reinforced concrete arch, some 250 ft open, 100 ft tall and 10 to 15 ft thick. This item was to be built on site and partly buried under ground level. Twelve such modules were needed for the complete hangar, with a total intended length of the factory of around 1.200 ft. Of the planned twelve sections, seven were actually built between mid-1944 and the end of the war.

Despite the intended scope was that of hiding the factory to protect it from aerial reconnaissance, due to the size of the construction works the object was reportedly spotted by US aircraft, but not attacked. Actually, the special construction was tested against explosives by the US Army after the war, resulting in the collapse of all modules except one, which is still standing today besides the pretty sizable relics of the others.

The site is not actively guarded, but it is located in a regional nature preserve, so access is through a nice walk in the trees. Once next to the hangar you can find multiple access points.

Close to the main arch, the only one still standing, it is possible to find an explanatory panel in German only. It commemorates also the forced laborers from the nearby concentration camps, who had to take part substantially in the construction works.

Walking under the arch is at your own risk, cause despite the bulky appearance of the structure, smaller pieces of concrete are hanging from from the ceiling. However, a walk inside will give you the most striking impression of the size of the hangar.

Just nearby the remaining module to the west you can find a walkable, half interred bunker, likely with a technical function which is today hard to imagine.

The module still standing today is the westernmost of the hangar, so walking east you will have the chance to step on the roof of the demolished modules. A number of thick iron rods can be spot at ground level.

Walking along the former southern side of the hangar, you can spot a deep well, probably part of the construction strategy. It may have been used to take out the gravel from beneath the base of the arches to lower them to a rest position on more compact ground.

Along the same side you can find a way to walk below the fallen structure. You can also get a view of the edge of one of the modules.

The eastern end of the complex is probably the most hazardous, cause you find an unprotected concrete cliff a good 10 ft high, constituted by the edge of a fallen module.

All in all, the place is a nice example of the undeniable structural design abilities of the German military, really interesting to visit both from a technical viewpoint and as a witness of the utopian visions of the Nazis, which unfortunately cost the lives of many.

Getting there and moving around

Reaching the trail-head is very easy by car. Leaving Mühldorf am Inn for Waldkraiburg along the road St2352, about 0.5 miles south of the crossing with St2550 you will find a sizable gravel factory to your right, preceded by an unpaved road taking west in the trees. You can park on the unpaved road on the northern side of the factory – probably a heir of the original factory built to feed the construction works of the hangar.

From there, you should take the unpaved trail into the trees, closed to vehicle traffic. It is another 0.5 miles to the site, on a flat and easy trail. A quick scan of the Google map will allow you to plan the trip. The place is not remote, cell phones work and you may use a virtual map to get oriented on site. Visiting might take about 2 hours for a very interested subject, including the trip from the parking and back, plus all time needed for pictures .

Hitler’s Wonder Weapons in Northern France

Following the end of the Battle of Britain, mainly fought in the air in summer-fall 1940, the plans of the Axis for an invasion of Britain were halted and progressively updated and reconfigured. The successful invasion of Holland, Belgium and Northern France had led to a stabilization of the border of the Axis territory on the Atlantic coast of Europe earlier in 1940. Since then and until the counter-invasion by the Allied troops in June 1944, the military command of Germany decided for the fortification of the coast with the Atlantic Wall, a series of naval gun batteries, ammo storages, barracks, radar stations, command and communication centers, and everything else that was needed to detect and contrast an attack from the West, both from the sea and from the air.

But the coast of the Atlantic was not considered only as a border line to be defended. Some large-caliber cannons of the Atlantic Wall built in the region of Calais on the narrowest sector of the English Channel, were capable of hitting targets on British mainland. Furthermore, many port towns on the cost of France were converted into military ports from where the Kriegsmarine operated regularly with various material, including the famed underwater U-Boot forces, running offensive missions against all sorts of Allied ships in various sectors of the North Sea and the Atlantic ocean. Airbases were routinely operated in the regions of Northern France, Belgium and Holland both for bombing raids over Britain and later for fighting missions in defense of the occupied and the innermost territories of the Reich from the Allied bombing runs. With the help of the US, these began to systematically target the Axis in 1943, operating from Britain.

Finally, the newest and most advanced conventionally armed weapons of WWII started to be operated from the coastal area in 1944 by the German armed forces. The famous ‘Retaliation Weapons’, or ‘Vergeltungswaffen’ in German – from which the famous abbreviation ‘V’ of the V-1, V-2 and V-3 – suffered from limited range, and so had to be launched from close enough to their intended target – Britain, by design. Today some relics of the launch sites and some buildings connected with the deployment of such ordnance can be visited when touring the area of the Pas-de-Calais, the northernmost province of France.

The following photographs, taken in summer 2016, portray four notable sites of the kind in that region.

V-1 – Ardouval

Since 1943 new weapons enriched the arsenal of the German armed forces. The famous V-1, manufactured as Fieseler-103, reached operational readiness and began to be deployed that year. This relatively simple, subsonic, air-breathing – i.e. non-rocket-propelled – flying bomb, while not very accurate, could be deadly against large target cities like London. Its limited range forced deployment in the occupied territories closest to Britain.

Many launch bases were prepared in Northern France, from where Southern England was well within range. The V-1 was used only after the D-Day – the first registered operative launch was on June 13th, 1944, against Britain. By the end of Summer 1944 the Allied had pushed the Germans roughly back to the region of the Ardennes in Northeastern France, on the border with Belgium. Consequently, all bases in Northwestern France were silenced. Later in the war, V-1 were still launched against liberated Belgium and central England, from more inland and further north bases by the retreating German forces. Total launched V-1 were actually in the order of the tens of thousands.

The Ardouval site is possibly the only V-1 site officially opened to the public in France. It is an open-air museum with no fences, so it is open h24 every day of the year. The site was severely hit before by Allied air raids before it could enter service, so no flying bomb was ever launched from it. Actually, the bomb craters can be clearly spotted in the trees all around. Going far from the paved walkways is not advised due to danger of unexploded ordnance.

The installation is rather extensive, and traces of some original buildings and service roads remain to this day. Among them a concrete water basin, a generator building, a building with a concrete arch for aligning navigation instruments prior to the launch.

Two curved trails from the V-1 body storage to the operational buildings and launch ramp can be spotted. The launch ramp was reconstructed, but just besides you can see the launch observation bunker, with a slot for visual checking the launch from very close to the lower end of the inclined ramp.

Barely recognizable ruins of other buildings can be spotted as well. Touring the place is not complicated, thanks to an explanatory panel close to the parking. It is advisable to take a picture of it with your phone, to be sure to see everything the site has to offer. Time required is about 45 min.

Getting there and moving around

The site of Ardouval (Val Ygot) is located close to the town of Ardouval and Pommeréval. It can be easily reached by car from the latter, less than 2 miles from the town center, driving west on the D99. Large free parking on site.

V-2 – Watten & Wizernes

Much more advanced than V-1, the V-2 was the first operational rocket in the world. Invented by the team of Wernher von Braun and tested in Peenemünde, on the border between today’s Germany and Poland, this liquid-propelled rocket came in the latest stage of WWII. The production totalled around 5000 units, and about 3100 were actually launched during the war, basically only from mobile launch platforms. Targets were mainly Belgium and Britain, but the first successful launch took place against Paris in September 1944. As for the V-1, range was among the weaknesses of the design, so that a deployment close to the Atlantic coast was necessary for targeting Britain from mainland Europe.

Mobile gantries were well designed and allowed a relatively fast re-deployment, a critical feature in the last stage of the war when the frontline was moving eastward at fast pace. Despite that, Hitler’s personal preference was with huge, autonomous, fixed launch bases, for which design and construction work began soon after the occupation of Northern France.

Two sites were created. The first was close to Watten, in the forest of Eperlecques – about 40 miles from the coast to the south-east of Calais – and was codenamed ‘Kraftwerk Nordwest’. Work on this monstrous bunker – probably the largest you will ever see from this age – started in early 1943 in a forest, at ground level and with little natural defences.

This installation was designed for the assembly of V-2 rockets arriving by train, and for supplying them with oxygen prepared in place in a dedicated branch of this bunker-factory. The intended role of this installation was the creation of a ‘rocket revolver’, capable of launching rockets at a frequency of 1.5 per hour, 24 hours a day. The Allies did not overlook the potential strategic relevance of the site and bombed it repeatedly. During a raid carried out by US forces in summer 1943 the site still under construction was seriously damaged. Since then it was decided to turn it into a liquid oxygen production factory for supplying other launch sites. Soon after the disembarkment, the place was finally abandoned after being hit by Tallboy bombs by the British. After capture in September 1944 it was decided to further demolish it by testing several new ordnance against a target so hard to crack.

The site is open as a regular museum, which can be visited on self-guided tours. A trail in the trees leads you to the main bunker, the tallest part of which can be entered. A V-2 mockup allows you to appreciate the proportions of the building. Some of the tunnels can be seen from the outside.

Also in place are a V-1 launch ramp, cannons and vehicles. Time required for visiting may vary between about 30 minutes to more than 1 hour depending on your level of interest.

The second site was built starting mid-1943 close to Wizernes, and not far from the previous site in Watten. This was codenamed ‘Schotterwerk Nordwest’, and it was intended for the same basic scope of the other, but it had also to be built to avoid heavy damage from air-dropped bombs. The location was extremely favorable, making use of a former quarry, with tunneling in the body of a U-shaped hill. A distinctive feature still remaining today is the concrete dome covering part of the site. The place was stricken with usual and Tallboy bombs after the D-Day. This caused the collapse of the entrances to the tunnel system, and of the side of the hill. The dome moved and banked to on side, but notably it did not break apart.

The place is open as a major documentation center. Besides the usual IMAX theatre in a building close to the parking, you can visit on a self-guided tour both the tunnels in the side of the hill and the area below the concrete dome – it can be incredibly hot and suffocating there, where it’s cold in the tunnels. You can find here much information about the history of the site and more in general of the deployment of the V-1 and V-2 in the area. A complete visit without the IMAX may take 45 minute to 1.5 hours depending on your interests.

Getting there and moving around

Both sites are easily reachable by car. The site of Watten is located is about two miles west of the town. You can reach it driving west on the D207 from the crossing between D207 and D300. A road called Rue des Sarts takes to the right after about .6 mile. The local name of the place is ‘Le Blockhaus d’Eperlecques’.

The site of Wizernes is located on the D210 about 1 mile south of Wizernes. The local name is ‘La Coupole’ – the Dome’.

Both sites are clearly signed.

V-3 – Mimoyecques

The hatred against the indomitable British enemy reached a pinnacle with the deployment of the V-3, reportedly Hitler’s favorite, a supercannon capable of shelling London from a distance of around 100 miles. The installation in Mimoyecques, close to Cap-Gris-Nez, about 8 miles southwest of Calais, was single-targeted against the ‘symbol town’ of London, for the cannon could not be oriented – it was built inside a hill and pointed upwards in a fixed attitude. The design was based on the older idea of multiple-charged shells, i.e. shells which were accelerated gradually to a very high target speed while running along an exceptionally long (430 ft) barrel. The site in Mimoyecques, codenamed ‘Bauvorhaben 711’, by design accommodated 25 such barrels, allowing the battery to shoot at the very high rate of 10 shells per minute, all the day round. The tunnel was designed to allow a train entering it.

Work on the site began in summer 1943, but the site never reached completion and was severely hit in summer 1944 by Allied bombing raids. President Kennedy’s elder brother reportedly died in an accident on one of them. It is noteworthy that the novelty and originality of the design disoriented Allied intelligence, who did not understand the role of the installation before capture in September 1944.

The concept of supercannons, albeit never provedly succesful from an operational viewpoint, was destined to emerge again in recent history, with a similar installation proposed by Iraqi dictator Saddam Hussein and designed with the help of a Canadian company – its manager being reportedly killed by the Mossad to hamper realization.

Together with the other ‘V sites’, Mimoyecques was almost completely demolished in order to avoid any further strategic use. It is reported that Winston Churchill in person pushed for this, to the aim of preventing the yet-to-be-established government of France from any action against Britain – some speculate that what the Prime Minister likely feared was the establishment of Communist rule in France.

This is site is not so famous as the V-2 sites, and not similarly ‘institutional’, yet there are opening times. You can go on a self-guided tour of the tunnels, where you can find many explanatory panels, as well as a reconstruction of one of the barrels. It’s always too warm for me, but I must say this time it was incredibly cold inside… The visit may take 30-45 minutes. Guided tours are available in French.

On the outside, just besides the tunnel entrance you can find a steel plate once on top of the site armouring the outlets of the barrels. The concrete construction on top of the place lies on a private property. I could only take one pic before being forced to withdraw…

 Getting there and moving around

The area is very nice, with the lovely Cap-Gris-Nez and Cap-Blanc-Nez a few miles away. The site can be reached on the D249 between the small towns of Bainghen and Landretun-le-Nord. Large free parking on site.

Frank Lloyd Wright in California

Frank Lloyd Wright’s buildings in California include many works from various stages of his artistic development. Considered together, these offer a good insight in the evolution of his style.

Differently from the front-page works visible elsewhere in the US, the buildings in California are mostly privately owned still today, so on one side they are totally part of the urban landscape and not just museums – they are still used for their intended function. On the other hand, they are not accessible to the public. To say it all, some of them are up for sale and a few in a state of disrepair. You may try scheduling a visit with a seller sometimes, but you’ll probably receive no answer if you say you just want to take pictures, at least if you ask to go for free…

Anyway, in some cases even looking at these buildings from the outside may be interesting for architecture-minded people, and this is usually possible.

The following photographs show some of FLW’s buildings in the metro areas of LA, SLO and SF. They are listed in chronological building order.

Sights

The following map allows to quickly check the position of the sights listed below. These are not all FLW sites in California, but only those I’ve visited and which are described in this page.

Hollyhock House – LA

This house is also known as Aline Barnsdall’s house, from the name of the lady who commissioned it. The building is an exception in the panorama of FLW’s houses in LA, for it is usually opened to the public (see website here for visiting info). It was designed and built between 1917 and 1920, some 18-20 years before the famous ‘Fallingwater’ (Kaufman’s house) in Pennsylvania.

Similarly to most buildings of FLW in California, the typical prairie style with exposed red bricks is altered to include concrete elements studied to prevent excessive heating. The decoration, the balanced use of very simple shapes to create an articulated façade and the prevalence of horizontal lines are all characteristics of FLW’s architecture which can be appreciated also here.

The place can be reached easily on 4800 Hollywood Blvd., on top of a small hill. Parking inside is possible.

Charles Ennis House – LA

This private house is located on the same hill as the Griffith Observatory, and has a wonderful panorama to the south and LA. With respect to other works of FLW, this is particularly massive and develops consistently along a vertical direction, while still retaining a good proportion between the area of the base and the overall height. Another distinctive feature is the façade composed of prefabricated concrete blocks, a feature that can be found also in others FLW’s houses in LA. Ennis house dates from 1923-24, when the size of LA was exploding.

You can reach the house on 2607 Glendower Ave. Public parking possible nearby.

Samuel Freeman House – LA

This smaller private house is particularly interesting for it was damaged by some seismic activity and looked in partial disrepair when I last visited in 2014. This made it possible to come close to it and have a close look to the prefabricated concrete bricks constituting the basic building module. The plant of the house is more complicated than Ennis house, but the size is comparatively much smaller, and the building less imposing. Similarly to Ennis house, Freeman house dates from around 1923.

It can be approached easily on 1962 Glencoe Way, a quick detour from Hollywood Blvd. and Franklin Ave., very close to the Hollywood Bowl. Limited public parking around.

John Storer House – LA

This is a private mansion built in the same years as Ennis and Freeman houses (around 1923), with which it shares much of the architectural features, including the building materials. It is comparable in size to Freeman’s house, but is more mimetic, cause it is separated from the road by a small garden and built very close to the side of the hill.

It is located on the hilly section of Hollywood Blvd., exact address 8161, to the west of the intersection with Laurel Canyon Drive. Very limited public parking nearby.

Wayfarers Chapel – LA

The design of this chapel at a first glance is a departure from the traditional prairie and usonian styles adopted for residential buildings by FLW. Yet at a closer look you realize the main features of functional-organic architecture are all there, reflected by the choice of materials and the inspiration of the shape of the chapel taken from natural structures.

Once inside you feel like being in contact with the exceptional surroundings, which are not just in the backstage, but all around in the premises of the chapel.

The complex dates back to the late Forties. It is on the tip of the beautiful Palos Verder peninsula, south of LA. The exact address is 5755 Palos Verdes Drive South, Rancho Palos Verdes. No serious walking necessary for visiting, the place is open to the public and is in the list of historic landmarks. Website here.

W.C. Morris Gift Shop – SF

This shop was the result of a radical restoration of an existing space between 1948 and 1950. The very central location next to Union Square has made it the perfect place for art galleries and luxury exhibition rooms. Actually until recently the place hosted an art gallery. The spiral ramp leading to the first floor was inspired by the Guggenheim museum in New York City, which FLW had started designing in 1943. The brick façade is a one-of-a-kind example in Wright’s production and in the panorama of San Francisco.

The address is on 140 Maiden Lane, .1 miles from Union Square.

Anderton Court Shops – LA

Barely noticeable after somewhat losing its architectural unity due to later additions, this building shows its FLW roots thanks to the vertical spire, typical also to other designs of this architect. The building dates from 1952, and was conceived as shopping center. Since then the property has been divided, and some changes to the facade applied.

Centrally located on 333 N. Rodeo Drive.

Kundert Medical Clinic – SLO

This building was completed in 1956 and specifically designed as an ophtalmological clinic – a unique example in the list of works of FLW. It turned out to be one of the last designs by this architect, who died in 1959. The building makes the best use of a standard size lot in central San Luis Obispo. Today it is still used as a clinic. The red bricks, flat shape, and the assembly dominated by horizontal lines are typical to the style of FLW.

The address is 1106 Pacific Street, San Luis Obispo. You can park right in front of the building, which is centrally located.

Marin County Civic Center – SF

The place was designed beginning 1957, but it was not completed until 1966, well after the death of FLW. This is one of the few institutional buildings of FLW, and unique in the panorama of American public offices. The location in the hills of San Rafael is very quiet and relaxing, and the building is hard to spot until you get very close.

The view from the terrace and the side walkways is very relaxing, as the building is still today surrounded by nature. The warm tones and the ‘human proportions’ of the inside invite to spend some time there, differently from more usual public buildings.

The area can be reached on Peter Behr Dr., San Rafael – there are actually several ways of approaching it. Large parking to the back of the building.
