Plokstine – A Preserved Nuclear Missile Site in Lithuania

While almost all nuclear sites you can find in European Countries once beyond the Iron Curtain are today totally abandoned and fairly unaccessible, there exists a perhaps unique exception. The Plokstine site in northwestern Lithuania has been selected around 2010 for complete refurbishment with the help of public money, and in 2012 it has opened its doors as a museum. Located in a beautiful natural setting crowded with hikers – namely Zemaitija National Park, a national recreation area around Plateliai lake – it has quickly grown to international fame, and is now recording several thousands visitors per year, with guided tours in multiple languages – including English – offered on a regular basis during the warm season.

What is today an intriguing tourist destination, used to be part of a large Soviet installation for launching ballistic missiles armed with nuclear warheads. It is worth mentioning that Lithuania was a ‘Soviet Socialist Republic’ in the realm of the USSR, i.e. not just a satellite country of the Soviet Union, but part of it. Actually, this small country on the shores of the Baltic Sea, on the extreme western border of Soviet territory, was an ideal location for deploying weapons to hit European targets from within the Union. Furthermore, the Plokstine forest was – and still is – a little populated area, where construction works for a large top-secret military facility for storing and operating offensive cutting-edge hi-tech warfare would go likely unnoticed.

The missile complex was completed in December 1962, in the years of Khrushchev and Kennedy. The Plokstine site comprises of four interred silos and an extensive underground command station in the middle – the ensemble constituted a so-called ‘Dvina’ launch complex.

The ‘Dvina’ site in Plokstine was actually the last part of the missile base to be built. Two more sister surface sites, with four launchpads each, had been completed one year before, just west of the nearby village of Saiteikiai. These surface sites were similar to those you can find in Latvia (see this post), a neighbor country where unfortunately the last remaining ‘Dvina’ site was demolished in 2017, but abundant traces of the Soviet presence can still be found.

All three launch complexes in this region were designed around the R-12 missile. The R-12U missile was actually used in the underground ‘Dvina’ complex, slightly different from the surface-launched R-12. This weapon was better known by its NATO designation – SS-4 Sandal – and was a 2.3 megaton, single warhead, single stage nuclear missile. It reached true international notoriety before the base in Plokstine was activated, for this was the type deployed to Cuba in the missile crisis of 1962. Coincidentally, part of the staff transferred to Cuba in the days preceding the crisis was from the same rocket regiment of the Red Army (the 79th) stationed in Plokstine. Sandal missiles from here were reportedly transferred in complete secrecy to Cuba, via the port town of Sevastopol in Crimea in that occasion.

The base remained operational until the last missile – by then obsolete – left in 1978.

The Baltics were the first republics to leave the dying Soviet Union, openly defying the military authority of neighbor Russia. After the collapse of the Union and the end of communism in Europe, these three states – which historically do not belong to Russian culture – quickly joined the NATO and European Union, to escape Russian influence as much as possible. Most Soviet military installations were shut down and abandoned, and have been for two decades an interesting destination for explorers and war historians (see this post for many examples). Later on, most sites have been slowly demolished or converted into something else. Really a few of them have been preserved for posterity.

In this post you can find photographs from the Cold War Museum now open in the former ‘Dvina’ site of Plokstine, from a visit in 2017. Close to the bottom, you can find a few further photographs from a previous visit made by appointment in 2009, before the site was selected for renovation – these may be more appealing for Soviet-aura lovers!

Sights

What can be visited today is all in the area of the old ‘Dvina’ complex. The complex is mainly composed of four interred silos, covered by heavy steel & concrete bulged covers, placed on the four corners of a square. These gigantic caps are the most prominent components of the site from the outside. Today, an observation deck has been erected on the south of the area. From there, you can appreciate the distinctive plan of the ‘Dvina’ complex, with an access road terminating in a loop touching all four armored silo covers.

The weight of each cover is told to be around 100 tonnes, as it was armored to withstand a nuclear explosion. The covers would be pulled sideward with a sled mechanism, to open the silos before launch. Unmovable missile launch complexes, like the ‘Dvina’ site in Plokstine, were easy and attractive targets for western weapons, thus requiring a very strong defense barrier. Similar considerations led the design of the Titan missile sites in the US, which albeit more powerful and capable of a greater range, are roughly from the same era (see this post).

To get near the silos or get access to the museum, you need to pay a ticket and join a guided tour. The visit includes a tour of the Cold War Museum, which has been prepared inside the rooms of the former control center. The tour will start from the visitor center, a new modern building. You will soon go through a specimen of the original fences which ran around the ‘Dvina’ complex, and which included barbed wire and high-voltage electrified lines. Close by, you can find traces of original unarmored constructions, likely service buildings. The missile site was operated by more than 300 troops stationing in a number of smaller centers in the area around the complex.

The guide will lead you along a walk around the surface part of the complex, where you can see the construction of the caps from very close. The metal part is very rusty, but the concrete cover has been refurbished and looks like new – a pretty unusual sight, for connoisseurs of Soviet military relics!

Access to the underground missile service and control center is via a small metal door, right in the middle of the square formed by the four silos.

A few rooms in the control center today host the exhibitions of the Cold War Museum. A room displays a quick time-line of the Cold War, since the end of WWII to the end of the USSR. In the adjoining rooms you can find propaganda items

Another room is about defense against nuclear threat. This is interesting, with many artifacts like dosimeters and medical tools, plus easily readable instructions of ‘dos and don’ts’ in case of nuclear attack.

Another room is about the evolution of weapons over the Cold War decades, with original material from the time, including heavier tactical weapons.

The exhibition is modern, small but not superficial, and may appeal to any public, including children. Besides the exhibits, you can appreciate the relatively small size of all rooms and connecting corridors in the former control center.

As you are driven next to the missile operation part, you can find a scale model of the ‘Dvina’ complex and a cut-out of a R-12U silo, together with a map of the relatively few missile sites in Lithuania – from the map, it can be argued that, for some reason, many more sites were prepared in nearby Latvia.

Resting quarters for the troops and a communication station with original electronic gear have been reconstructed based on original footage and pics. Communication with the military headquarters was clearly an essential task – it was the only way an order to launch could be issued – and the serviceman on duty was responsible for assuring a permanent link with the chain of command. In other words, he was instructed not to leave his headphones under any circumstances, during a several hours-long shift!

On the sides of the corridors you can see holes for the extensive network of cables and pipes. Further on, you meet the most ‘hardware’ part of the exhibition. First, the original diesel-fueled power generator has been refurbished and is standing in its original room. The underground complex was designed not only to withstand a nuclear blast, but also to provide shelter for all servicemen for several days following an attack. This meant air filters, food, water, technical supplies and of course electrical power, were all essential assets. Oil for the generator was stored in a container in an adjoining room.

Finally, you get access to one of the four silos. You need to go through a tight door opened on the wall of the concrete structure of the control center. Writings in Cyrillic can be spotted on the walls in this area. From there, you will see the cylindrical shape of the metal structure of the silo from the side. This metal canister is really big, the ‘Dvina’ silos featured a much greater diameter than the SS-4 missile they were built for. This was somewhat different from their US counterpart (see this post), where the missile diameter fits the size of the silo without much margin.

You can get access to the silo via the original hatch, cut in the metal wall close to the rim on top of the silo, just beneath the external cap. Going through this hatch is incredibly difficult – it is extremely narrow, much longer than the size of a human step, and tilted upwards! It is hard to understand why the Soviets built it in a size so small – this applies to the control center too, for all corridors are really narrow and the ceiling in the rooms is so low you may easily need to bend forward! For those who don’t want to try the original entry to the silo, there is now a non-original door cut in the side of the canister.

The inside of the silo can be observed from an original service deck, immediately under the external cover. From here you can clearly appreciate the size of the construction – the missile was more than 70 ft long, and sat here in a vertical position. The SS-4 was among the first missiles to make use of a storable liquid propellant, which allowed it to stay in almost-launch-ready conditions for a prolonged time, if resting in a silo. Nonetheless, the time for opening the armored caps was about 30 minutes, which meant this was not exactly quick to launch. The understructure of the armored caps can be clearly appreciated from inside the silo.

Photographs Before Restoration Works – Ghost Base

When I visited this site for the first time in 2009, it was open only by appointment. Unfortunately, I had only a compact camera at the time, and the very low light inside plus a rainy day outside, meant I could take only a few acceptable pictures.

However, they provide an idea of the state of the ‘Dvina’ complex before it was decided to reconfigure it as a museum.

As you can see, the armored silo caps were in a worse shape than today, yet not heavily damaged. The barbed wire fence around the four silos was probably original Soviet.

Inside, the control rooms were basically empty, except for some communist emblems and flags. Green wall paint and Cyrillic writings could be found even at the time, so what you see today is likely original. The generator, whilst in bad shape, was there.

The silo could be accessed only via the original hatch, and except for the partial darkness, its appearance is similar today.

It is out of doubt that the ‘Soviet ghost aura’ of the base was somewhat lost in the restoration process, yet credit must be given to the effort of the local government in preserving a rare and relevant trace of military history through an expensive restoration process.

Getting there and moving around

The Cold War Museum (Šaltojo karo muziejus in the local idiom) is located in the Zemaitija National Park, northwestern Lithuania, east of lake Plateliai. Access is via the road 2302. The place is totally accessible and well advertised locally. Visiting the outside of the armored caps and inside is possible only with a guided tour, offered in many languages including English, and lasting about 50 minutes. No fee is required for climbing on top of the observation deck. Full information through the official website here.

The Salpa Line – Finland’s Anti-Soviet Barrier

Possibly one of the world’s best preserved military installations from WWII, Finland’s Salpa Line – the name ‘salpa’ meaning ‘latch’ – is a defense line composed of about 700 reinforced concrete bunkers with anti-tank cannons and machine-guns, more than 200 miles of anti-tank obstacles, roughly another 200 miles of trenches pointed with over 1200 machine gun nests, 500 artillery positions and more than 700 quartering dugouts. All this, and everything necessary to operate this enormous war machine, including hundreds of miles of new roads, electric cables, dams, telephone lines, etc., was built to defend the border between Finland and the Soviet Union.

History – in brief

The Winter War

Finland enjoyed the rigors of WWII since 1939, when following the Ribbentrov-Molotov pact between Nazi Germany and the USSR, it was agreed off the records that this Country should enter the sphere of influence of Stalin’s communist dictatorship. Finding no other way to submit the Finns, Soviet troops attacked Finland from the East all along their common border, from the Gulf of Finland up north to the Barents Sea, at the end of November, 1939.

This rarely told chapter of WWII is known in Finland as the Winter War. Finland, which on a September 1939 map looked somewhat larger to the east than it looks today, fought fiercely against a numerically much superior enemy, which at the time was not engaged on any other major front. Despite the very difficult situation, with no help – except limited arm supply – from the outside, the motivated Finnish Army led by General Mannerheim recorded some marked victories especially in the central sector of the border, and managed to avoid a complete defeat. This unexpected military resistance, and the promise of Britain and France to support Finland had the war continued further, led the USSR to agree upon a peace treaty as soon as mid March 1940, basically crystallizing the military situation reached at the time. As a result, the border moved west by about 60 miles in southern Finland, with the loss of the Karelian Isthmus and the city of Vyborg, the access to lake Ladoga, Finland’s Eastern Karelia – simply known as Karelia in Russia – and a large territory in Lapland, mostly uninhabited. Finally, the peninsula and port town of Hanko, 70 miles west of Helsinki, was ceded to the USSR for 30 years.

Building the Salpa Line

It was at the end of the Winter War that Finland’s government, following the suggestion of General Mannerheim, took the decision to built the Salpa Line, to defend the new border against any possible attack of the Soviets.

Construction work on this impressive system, made not only of a chain of forts, dugouts and barracks, but also of an extensive network of communication and transport infrastructures, was carried out mainly between spring 1940 and summer 1941, Finland’s so-called Inter-War Period. Up to 35’000 workers – mainly civilians from private companies – were involved, roughly bringing the defense line to completion by mid 1941. The line was designed primarily to protect the most populated and easily accessible part of the Country in the south, and a major concentration of strong points was erected along todays border line with Russia, between the Gulf of Finland and the town of Joensuu.

At the same time, a smaller branch of the Salpa Line was erected on a much smaller scale on the new border with the USSR, along a 3 miles line cutting through the Hanko peninsula.

The Continuation War

In the period between the end of the Winter War and the surprise offensive of Germany against the USSR in June 1941, the Nazi Wehrmacht had successfully annexed Denmark and Norway to the Third Reich, thus becoming a neighbor state for Finland, just like the Soviet Union. In the process, Finland allowed Germany to transport troops and material to northern Norway moving on national land, and receiving arms in return. In the same period Hitler refused to endorse further Soviet attacks against Finland, thus further narrowing the diplomatic distance between Germany and Finland, which nonetheless managed to remain independent throughout WWII.

When the war broke out between the Soviet Union and Nazi Germany, Finland took the initiative and attacked the USSR, soon regaining control of basically all territories lost in the Winter War, including the port of Hanko, by the end of 1941. The German Wehrmacht attacked the Soviet port town of Murmansk and the nearby area, rich of natural resources, from the northernmost Finnish region of Lapland.

Due to the quick movement of the front line back east, the Salpa Line saw basically no fight, and was maintained until the end of the war with the Soviets in 1944 as a rear defense line.

This phase is known as Continuation War, and quickly turned into a war of attrition along a stable border line. This equilibrium was cracked when the military situation started to get worse for Germany after the defeat of Stalingrad in early 1943. After months of negotiations with the USSR to put an end to the conflict, following a massive Soviet attack on the Karelian Isthmus in August 1944 and the second loss of Vyborg, an armistice was signed in September between Finland and the Soviet Union, in favor of the latter. It restored the border line as it was at the end of the Winter War and imposed a long-term lease of Porkkala – a peninsula on the Gulf of Finland 30 miles west of Helsinki – instead of Hanko. Also included were heavy war reparations and the neutrality of Finland with respect to further Soviet campaigns. Plus the immediate expulsion of all German forces from Finnish territory.

Nonetheless, differently from almost any other Country touched by the Red Army in the events of WWII, Finland managed to retain its complete independence from Stalin’s communist empire, and part of the credit goes to the existence of the Salpa Line, a major deterrent against any further Soviet military aggression.

The request to severe any contact with Germany led to the final chapter of WWII for Finland, the Lapland War, when the Armies of Finland and the USSR attacked the Wehrmacht in the north of the Country, starting a campaign lasting months until the final defeat of Germany, causing the total destruction of many villages and of the town of Rovaniemi.

Sights

As a result of the course of events, Finland’s fortified line of defense did not see any direct military action. This spared it for posterity as a notable example of military technology of the Forties. Of course, as war technology evolved rapidly soon after WWII, the Salpa Line rapidly became obsolete and was largely abandoned. Most dugouts, soft construction works as well as most wooden, unreinforced positions have been reclaimed by nature. Only traces of the trench lines exist today, except in those spots where they have been explicitly preserved for the public.

Heavy positions are a totally different matter. Except for a few mainly in the northern part of the Country, blown up by the Soviets in the months of the Lapland War to help expelling Nazi troops from the Finnish territory, most bunkers and strong points are still there, basically intact. The majority has been abandoned, but due to a demolition work being an economy nonsense, they can still be seen today.

At least two small groups of bunkers in the very south of the Country have been turned into top-level museums on local military history, with a modern visitor center, guided tours and so on. Some bunkers, like in Joensuu, can be visited as little local museums. A good number of the reinforced concrete installations have been left open for interested visitors, stripped of any dangerous military hardware, sometimes even partly refurbished, and in most cases they can be freely accessed – provided you find them. Some are included as checkpoints along official multi-miles hiking trails, which are among Finland’s top tourist attractions. More often, either you know where they are in advance or you will hardly find them in the wilderness.

For reaching most of the non-advertised bunkers of the Salpa Line, you need to drive to very secluded locations along unprepared roads. If you like this kind of archeology, this adds much to the fun!

The good news is that Finland considers the Salpa Line a historical landmark as a whole, thus any damage or alteration is strictly prohibited and severely prosecuted. So you are not to see your search frustrated by finding a bunker covered in graffiti or used as a shelter by ravers or drug addicts – as it is often the case with the much similar Atlantic Wall in France. This is also because except for a few cases the superstite installations are located far from any urban center. By the way, Finland boasts one of the Europe’s lowest crime rates, so exploration is made potentially dangerous only because of intrinsic – rusty barbed wire, mimetic manholes, narrow passages, total darkness … – or natural causes – badgers, boars and bears!

In the following a description of a few notable points of interest along the Salpa Line is presented. The list is extremely far from complete, as it would take at least several months of dedicated work to explore the Line in its entirety! Yet this selection provides a good specimen of all basic types of sight you can find along the line. Photographs were taken during a visit in summer 2017.

Map

The following Google map was created based on the very useful information provided on this website, which is an excellent starting point for any exploration of the line. Basic info on the corresponding Salpa Line sites are provided on it almost one by one, and pinpointed on a map, but apparently there is no comprehensive map on that website. The website is also Flash-based and totally ‘iPhone unfriendly’ – it simply doesn’t load on my iPhone 6S. So I can’t take any credit except for having put together all points and having made them smartphone accessible. The red signals refer to points pictorially described in this article. The area of Hanko and the museums of Mikkeli are not covered in the map, whereas some sites will be described in another chapter.


The list below is ordered roughly from the south to the north.

Virolahti Bunker Museum, Virolahti

This site – Virolahden Bunkkerimuseum in Finnish – is among the southernmost of the Salpa Line, conveniently located on the busy E18 connecting Helsinki to St.Petersburg. The museum is a good starting point for getting an idea of the features of the line. There is a visitor center with a modern setup, where you can see a collection of light weapons from both the Finnish and Soviet sides – actually many Soviet weapons left behind by the retreating Red Army at the beginning of the Continuation War were later reused by Finland’s Army. Much information is provided in a synthetic and readable way – both in Finnish and English – on the construction of the line and about the war history of Finland, with a focus of what happened along the sector of the front closer to the Gulf of Finland.

The outside part is organized along a short trail in the trees. The first main stop is a reconstructed trench, with an example of a spherical soft concrete bunker type, conceived to cover dugouts. Nearby you can see two small heavy metal turrets. These were designed to be partly interred, to form an armored machine gun nest. The thickness of the metal construction is stunning! There is also a line of stones put in the terrain, a typical anti-tank obstacle to be found in many sites of the Salpa Line.

A German-made Pak-40, 7.5 cm anti-tank cannon in perfect condition is presented in a reconstructed open-top field fortification.

Nearby, you can access a perfect example of an anti-tank bunker. Three main areas are featured in this type of bunker. First, a relatively large living and sleeping area, with bunk beds for troops, a big stove, a water sink, and an air pump. Second, a firing room with a 45 mm anti-tank gun permanently installed, with the barrel leaning out of a suitably designed blind window. Third, a firing room with a machine gun, with the barrel leaning out of an open slot cut through the thick concrete wall of the bunker. Both the cannon and machine gun fire basically in the same direction, from the front facade of the bunker, whereas the only way in is through a sealed door to the back.

The bunker is provided with a metal observation turret on top, accessible through a ladder mounted in a very narrow vertical tunnel with a sealed door.

Another original bunker you can visit in Virolahti is a quartering bunker, capable of sleeping 40 people. The construction is similar to the large living area of the previous bunker, but this is larger.

Examples of original trenches which have not been refurbished can be spotted as smooth grooves in the ground between the reinforced bunkers. Finally, there is also a collection of cannons – some of them very old – and machine guns, from the USSR, Finland, Sweden, France and Italy. Heavy cannons from various ages were provided by France at the time of the Winter War, and put in place along the Salpa Line in more points, so they can be spotted pretty often in Finnish museums.

Not a part of the museum, it may be interesting to check out what the frontier with Russia looks like today. You can come pretty close to the border zone driving south of E18, along the unpaved Kurkelantie road going to the small villages of Reinikkala and Kurkela. There is a well signed respect zone instituted along the border line, which cannot be accessed without all necessary papers and permits.

Nonetheless, the striped posts marking the border can be spotted with a zoom lens from the distance. I can’t guess whether in Soviet times the border did look like this, or instead it used to appear less penetrable. Of course it may be just a matter of appearance – when I was there, I personally didn’t even think to try coming close to Russia without an explicit permission, so I don’t know what may happen should you try to get near the border by entering the respect zone by foot!

The Virolahti site can be visited in something less or something more than 1h, depending on your level of interest. It is flat and easy to tour, with a large free parking nearby. Website here.

Salpa Line Museum, Miehikkälä

This is probably the biggest exhibition on the Salpa Line, and the most visited also. The visitor center proposes a series of itineraries for touring the site on a self-guided base. The highlights are anti-tank and machine gun bunkers, a plane spotting wooden turret, trenches of various types, cannons and more. Together with Virolahti (above), it is surely a place to be if you want to capture at a glance what the Salpe Line is all about.

The Miehikkälä site is unique in its own respect due to the morphology of the territory, with a rocky cliff prospecting on an area of wavy land. The two main armored positions with an anti-tank gun and a machine gun are atypical, dug deeply in the rock, accessible from the top of the cliff, with the barrels leaning out at the level of the surrounding terrain. The bunker with the anti-tank gun features an observation/firing turret directly accessible from the firing room through a very long vertical passage. In the living quarters there is a collection of rifles.

The bunker with the machine firing chamber presents preserved sleeping and living quarters, and an observation turret.

Ahead of the rocky cliff you can find two armored turrets like in Virolahti, and an example of the most typical anti-tank barrier of the Salpa Line, made of aligned big rocks put in the ground. This is a distinctive feature of the Salpa Line, and following the rocks may help to find the location of more secluded bunkers in other sites.

Another interesting item is an old Soviet T-34 tank with the corresponding shelter.

To the back of the cliff you can find a German-made Pak-40 anti-tank cannon in an open-top field fortification. Looking in the direction of the barrel, you can see a long grove aligned with it. This is a tank trap, where the tank was forced to slow down trying to cross the grove right on the line of fire of the anti-tank gun.

In a second part of the site it is possible to find a group of rare concrete trenches, mostly similar to WWI constructions you can find in northern France (see this post), a housing bunker with a water reservoir on top and a standard anti-tank/machine gun bunker. These could be seen only from the outside when I visited.

The museum is not difficult to find, and there is a large free parking on site. The visit may take from less than 1 hour to more than 2 hours, based on your interest. While not difficult to tour for an average physical condition, you’d better go prepared to climb many stairs, move along narrow passages and walk short trails going steeply uphill. Website here.

Hostikka Site

The Hostikka site, deep in the countryside north of Miehikkälä, is composed of a handful of bunkers scattered a few miles apart along the roads in the municipality bearing this name. On each site there is a complete description in Finnish and English, and a map. Most sites can be freely accessed, a few are normally closed and can be opened on request, usually visiting with a ranger. A comprehensive map in Finnish can be found here.

From the south, item B186 is a massive anti-tank/machine gun bunker which is normally closed. The guns can cover a flat field ahead of the facade of the bunker.

A bare 300 ft north along the unpaved main road you meet B182, a machine gun bunker which can be toured freely. You can recognize the sleeping quarters and the observation tower. Climbing on top, you can appreciate the mimetic installation of the bulbous top of the armored tower. There is also what appears to be a firing hole close to the main sealed entrance.

All armored doors are still there, together with an extensive piping system.

Driving north for about 0.3 miles crossing the small village of Hostikka, you can find another site, with a preserved trench system, a machine gun and quartering bunker, open but unfortunately severely flooded, and item B166, a huge cave. This is not the only cave excavated in the rock along the Salpa Line. This multi-entry cave was intended for sheltering 80 people and providing access to open-top cannon/machine-gun dugouts. It was never finished, it is uninsulated and very wet.

The road going to Kirppu passes by items B150 and B132, standard anti-tank/machine gun bunkers. They are usually closed, but can be climbed and walked around.

All these bunkers unwind along a north-south direction, and are easily accessible parking nearby each site. Visiting may take 15 to 30 minutes for each open site, especially if you want to take pictures inside, less for closed bunkers where you may want to have a walk round. For inside pictures a tripod is mandatory, and a torchlight highly recommended.

Lusikkovuoren Cave

This cave can be reached driving for less than a mile on a secondary road departing eastwards from 3842 in Suo-Anttila. The cave is usually closed and sometimes used for public exhibitions or performances – a very suggestive location! -, yet the place deserves to be seen also from the outside. There are actually two neighbor entrances to the cave, which has been carved deep into the rock at the base of a cliff. The cave, intended to be used as a logistic interchange point, a headquarter and a weapons storage, was never completed. There are draining holes and a concrete pavement inside.

Hidden in the trees, far from any village, from the outside the cave really looks like a location from ‘The Lord of the Rings’!

Askola Site

The Askola site can be spotted while driving roughly halfway between Luumäki and Lappeenranta, along a busy road called Lappeenrannantie, next to the shore of lake Kivijärvi. There is a parking area just ahead of it. Heading straight to the big bunker you see from the road, you can find a map of the site. There is an uncommon concentration of armored positions in a small area between this trail head and the newly built highway N.6 to the south.

Despite the majority of the bunkers being normally unaccessible, there are some interesting uncommon sights here. The first is a reinforced dugout, where one of the bulky armored metal turrets you can see in the museums of Virolahti and Miehikkälä is interred in its intended working position. The turret can be accessed from behind and below, and a machine gun is mounted inside.

Furthermore, there are at least two original tank turrets recycled as reinforced firing positions. These turrets are apparently from BT-7 Soviet tanks, probably lost to the Finnish Army during the Winter War or the Continuation War.

More standard bunkers and dugouts can be found, but in some cases they can be barely neared due to wild vegetation.

About 0.8 miles to the west along the Lappeenrannantie road, you can find a small concrete dam – actually it lies in the courtyard of a private house… This is part of a system made to control the water level in the lake for military purposes.

Moving eastwards towards Lappeenranta, in the small village of Rutola it is possible to find another machine gun/housing concrete bunker, with an anti-tank barrier on the shore of the lake. This also lies on private land.

A visit to this site may take a 1-2 hours or more, depending on the level of detail and your ability to move around.

Syysphoja and Puumala Site

Along the beautiful scenic road 62 going from Imatra to Mikkeli it is possible to find two easily accessible forts of the Salpa Line. The first is located on Salpalinjantie road, departing north from the main road east of the village of Syyspohja. The facade of this well deceived anti-tank/machine gun fort, dug in a pile of land and hardly visible from the distance, is partly covered with stones. There are also partly refurbished dugouts and wooden obstacles, plus a long line of anti-tank stones.
