Military Collections in Sweden – First Chapter

When visiting the countries of northern Europe as a foreigner today, you may be easily captured by the beautiful landscapes and elegant architectures, as well as the great food options and the generally exceptional hospitality. Actually, a visit to Scandinavia will hardly disappoint, either in the summer or in the cold season. Everywhere looks like an ideal place for having a good time off.

However, digging in the military history of Norway, Denmark, Sweden and Finland, you might be surprised. Actually, since medieval times peaceful mutual relations have been built very slowly over the years in the area, going through centuries of unrest and struggle often culminating in open wars. In the global conflicts brought about starting with Napoleon until the end of the Cold War roughly 190 years later, the Countries around the Baltic sea have been in the center of a theater of operations of their own.

World War II and the Cold War

Looking at WWII and the Cold War era, the roles of Northern-European countries have been significantly different. Denmark, geographically untenable in front of the German enemy, was taken by Hitler’s Third Reich forces almost overnight, with Norway following shortly after. This gave birth to fierce resistance actions, trying to jeopardize the activities of the enemy. Norway was in the focus of much attention by the Western Allies, who tried to land in Narvik, sank battleship Bismarck, bombed the heavy water plant in Vemork, and transited in its arctic seas to feed Stalin’s Soviet Union with much needed supply (see this chapter). Conversely, Finland fought a fierce war against the USSR, ending up as an ally of Germany after the start of Operation Barbarossa, and finally turning against the Wehrmacht on agreement with the USSR, and managing to leave the conflict in 1944 (see this chapter).

Finally, Sweden did not take part to offensive military actions in WWII, managing to keep a neutral role through delicate diplomatic actions. For this neutrality to be credible however, the Country had to be defended, and its border – both on land and along the shoreline – actively guarded. This meant the construction of many forts all along the Baltic coast, to the west, south and east, as well as ground installations along the border with Finland. Similarly, the military tradition of Sweden, that in modern times date at least from the 17th century, when in the Thirty Years War Sweden managed to take a primary role in the balance of powers in Europe, was not discontinued at all. Despite neutrality, traditional manufacturers of fine firearms and shipbuilders were flanked over time by companies making excellent heavy-duty vehicles, armored tanks and aircraft.

In the Cold War period following the end of WWII, Scandinavia got a possibly even more central status, due to its proximity with the USSR and the control it could exercise on the sea accesses of the Soviet Union to the Northern Atlantic. Where Denmark and Norway joined NATO (see this chapter for Norway, this for Denmark), Finland and Sweden kept a neutral role. Once again, Sweden, not entangled in a complicated post-WWII deal with the USSR unlike Finland, could develop the credibility of its neutrality, preparing for defending against the Soviet threat with a build-up of its armed forces, and the development of original and high-tech military solutions, tailored to its territorial and climatic needs, carried out mostly in-house.

Traces in Sweden

The facts of WWII and especially of the Cold War in Sweden have left relevant traces, which are proudly preserved for the public either in world-class exhibitions, sometimes prepared on the very site of former military installations, or in smaller, well-crafted and much detailed collections, often run by groups of exceptionally passionate enthusiasts.

This and the following chapters cover some of them, offering a cut-out of what a visitor interested in military technology and history can find in beautiful Sweden. Photographs were taken in 2024.

Aeroseum – former Säve Air Force Base – Göteborg

Besides making for a testimony to the originality and commitment of Sweden military planners, the air force base of Säve, located about 4 miles north of the major town of Göteborg in South-Western Sweden, is truly a one-of-a-kind example of a Cold War installation. Conceived for anti-blast protection in the early years of the nuclear age, the base was designed to carry out all operations, except take-off and landing, underground. This included aircraft storage and servicing, but also refueling, loading, towing, and lighting the engines in corridors carved down to 100 feet underground in the hard Scandinavian rock!

The project had an anticipation during WWII, when some special aircraft shelters had been obtained on site by drilling the hillside. However, the actual digging of this incredible Cold War underground base was started in 1950, to be inaugurated by the king Gustav VI Adolf in 1955 (even if not totally complete at the time). The base was sized for a crew of 40 men staying underground with 15 aircraft, of the then new type Saab J29 Tunnan (which translates into ‘barrel’).

The plan of the underground facility features multiple accesses from ground level, on the sides of local hills. Entrances are all misaligned, to reduce the potential damage from a hit by a single attacker. The actual access to the descending tunnel driving down is through a colossal concrete sliding door, 2.3 ft thick and weighing 70 tonnes, with a front area such to allow a fully mounted aircraft to transit with sufficient clearance from the walls and ceiling!

Interestingly, the concrete door is preceded outside by a curtain, which together with traffic lights, switch cabinets and cables can still be seen today. This was installed for further protection to prevent the effects of fallout and contamination, in case of a nuclear attack on the base premises. The heavy curtain could be effective in stopping debris and lower-energy contaminated particles from even touching the doors. Soaked in water for cleansing, it could be then potentially re-employed multiple times, in case of a nuclear war scenario with waves of nuclear strikes.

This feature of the base, already pretty unusual, is the first to welcome – and strike! – the visitor. Then the tour takes you inside, for a full exploration of the underground facility beyond the massive concrete doors.

The feeling when accessing the tunnel is really of something huge. A description of the history of the base is offered as a first item through pictures, schemes and original crests. Then the roomy environment of the access tunnel, descending in a bend to the bottom part of the base, is stuffed with a rich collection of aircraft and helicopters in service with the Swedish Air Force, their engines and technical accessories.

The base of Säve was fully completed by 1963, including the fuel supply system which had posed some safety issues in its original design (fuel went down in case of accidental spilling, thus remaining trapped in the deep-end of the base). However, the F9 squadron of the Air Force, home-based in Säve, was disbanded just a few years later, in 1969. This meant that the underground airbase saw active service with the J29 and later the J34, the latter being the Swedish designation of the British Hawker Hunter. After 1969, Säve was home base to the 2nd Helicopter Squadron, and the underground part, hardly of use for rotorcraft, was then employed as a safe storage for non-active aircraft, notably the illustrious Saab J35 Draken, of which 70 (!) were long-term stored inside, with wings dismounted. The base finally ended its military service in 1998. The underground bunker was re-opened later as the Aeroseum museum, where most of the former airbase was turned into a civilian airport, still working today.

Among the aircraft on display in this first descending tunnel are a Saab J29 Tunnan, alongside its De Havilland Ghost jet engine (license-built under the designation RM2 by Svenska Flygmotor, later Volvo Aero, in Sweden). In service between 1948 and 1976 with the Swedish Air Force, the somewhat elusive J29, little known in the West, was a massively produced swept-wing fighter and fighter-bomber, with 661 exemplars manufactured! Austria, another non-NATO country lying on the border with the Soviet bloc, was the only foreign customer for this machine, which in the 1950s formed the backbone of Sweden’s defense force. A modern fighter in many respects, in the same class of the North American F-86 Sabre and of the MiG-15, the J29 was not easy to master for novel pilots, and unfortunately caused many accidental losses, at a time when Sweden was the fourth air force in the world in strength. It was actively employed in the Congo, where Sweden took part within the United Nations contingent in the 1960s.

On display are also the towing truck and generator employed for engine spool up. In a scramble, the aircraft could be towed up by this Volvo truck, directed on an open air apron, from where it could complete its taxi run alone and finally take-off.

Next in line is a Saab J35 Draken (meaning ‘dragon’), an iconic and successful supersonic fighter/interceptor from Sweden, first flown in 1955 and entering service in 1960, manufactured in 615 exemplars and not less than 10 variants. Besides the Swedish Air Force it was adopted by the foreign Air Forces of Denmark, Finland, and again Austria, the last to withdraw it from service in 2005! This Mach 2 capable machine, with a double-delta wing planform, was propelled by a slightly modified Rolls-Royce Avon engine (manufactured by Svenska Flygmotor as RM6). An original design from the Swedish school, among the features making it so versatile were provision for a two-seats airframe, as well as a general plant simplicity and undercarriage sturdiness, which together with a stopping parachute allowed its deployment from the wartime landing strips.

The latter were obtained in Sweden from the quick conversion of short sections of straight roads in the highway system, creating a network of so-called krigsflygbaser (‘war air bases’), in a defense plan called Bas 60 and later Bas 90. A solution to be found also in the Federal Republic of Germany in the Cold War years, this could greatly enhance the chance of survival of the air force following enemy strike on major air bases, through force dispersal. Yet not all aircraft can safely operate from similar airstrips. Swedish aircraft take this ability into account from the design phase, yielding dependable aircraft, capable of operations in far-from-ideal conditions.

Despite featuring a double, fixed-geometry and comparatively small air intake, the aircraft is single-engined. Underneath the fuselage, this aircraft features a ram air turbine (RAT), for powering the aircraft systems through kinetic energy in the airflow, in case of an engine shut-off in flight.

To the back of this exemplar of the Draken model is a Saab J37 Viggen (which is the name of a local species of duck). Another great example of an original design from Sweden, the J37 is an attack aircraft built in a canard configuration, and like its predecessor capable of short take-off and landing from road runways. Made in mode than 300 exemplars and employed uniquely by Sweden, it was in service between 1971 and 2007. Quite difficult to see out of Sweden, at the time of its introduction it was arguably the most advanced aircraft design to date, in terms of aerodynamic study, avionic suite and attack potential.

Developed in a number of variants for several roles, the exemplar on display features a number of payloads, to be attached to the underwing pylons or under the fuselage, also thanks to the good clearance from ground offered by the tall undercarriage (not to be found on the Draken). Differently from its Saab predecessors, the J37 was powered by a Volvo RM8, based on the American Pratt & Whitney JT8D turbojet, instead of a British engine.

Close to the Viggen, on display is a Saab car employed for friction test on the runway. This was rather widespread in airport facilities in Sweden. Vehicles with similar function can still be found everywhere in the world, especially in countries where runways are subject to icing.

Next in the line is the Saab JAS 39 Gripen, the most current evolution of the Saab dynasty of attack aircraft. Currently manufactured in more than 300 exemplars and exported to several countries, this machine is another original design from Sweden which is also a post-Cold War commercial success. A canard design like the Viggen, this model was introduced in the late 1980s, and it has been updated over the years as an air superiority platform, with a good mix of performance and efficacy, dependability and economical efficiency. Based on the Volvo RM12, derived from the American General Electric F404, it is currently in service. The aircraft on display is the oldest surviving.

Before reaching to the bottom, in one of the recesses along the corridor, photos from the construction phase of the bunker base, its inauguration and the years of operation can be checked out.

Also mentioned in the exhibition is the peculiar chapter of the Swedish nuclear program. The latter was envisioned in the early nuclear age following WWII, and it took shape especially in the 1950s and early 1960s. Besides facilities for the making of what was needed for fueling and managing a nuclear deterrent, on the aviation side Saab was tasked with dedicated projects for a delivery aircraft for nuclear ordnance, to flank the Saab J32 Lansen intended as an interim platform in that role. Project A 36, for an aircraft featuring a Viggen-like fuselage but no canard, and with an unusual overhead layout of the engine similar to the North American F-107, was in the pipeline when the government started to face increasing contrast from the public opinion concerning the entire national nuclear program, which was eventually cancelled in 1968.

Looking at the structure of the tunnel, left mostly untouched from the days of operation, the original wiring and piping for various systems – electrical, ventilation, etc. – can still be seen. The tunnel is also interspersed with frames, where light fire-proof doors could be lowered in case of an accidental fire. They could seal segments of the tunnel, which could then be flooded with fire-suppressing foam.

Approaching the bottom of the descending tunnel, it is possible to find a group of helicopters, in service in Sweden mostly for rescue operations, like an ubiquitous US-made Piasecki H-21 (the ‘Flying banana’), a Sud Aviation Allouette 2, an Agusta-Bell 402 and a Bell 206, the latter employed in polar missions from icebreaker Ymen. An Eurocopter Super Puma and a MBB Bo 105 come from the Swedish military, the latter reportedly having been prepared in a special anti-tank version, but never pressed into service.

Once on the bottom level, you can explore the halls, which are all interconnected, forming a network with a plant similar to a double ‘H’. On the crossing of two halls, you can spot the big round turntables, employed to turn the aircraft when towing them from storage to the base of the ramps going up. There are actually two of these ramps, one is that employed for access by visitors, the other is currently only visible from the bottom level, and off limits (employed for museum service). Its access can be found to the opposite side of the bottom level upon entering.

You can find several aircraft and exhibits on this level, including some pay-per-use professional flight simulators. An interesting exhibition tells about the organization of the STRIL, an acronym for stridsledning och luftbevakning, forming the backbone of the air defense system of Sweden from the early years of the Cold War on. Among the most unique facilities managed by the system are the krigsflygbaser mentioned above. Some original pictures and scale models tell about the detailed scheme of such bases, which could be activated when conditions required.

It is possible to board examples of both the Draken and Viggen models. The latter is presented with the engine dismounted from the airframe, and with many examples of war load either hanging from the wing pylons, or lying underneath. The number of options is really big, witnessing the versatility of the Viggen as an airborne platform.

The cockpit of the Viggen has evolved over time. The one you can see is fully analog. Close by is also the RM8 jet engine of the Viggen, with the afterburner pipe installed – a pretty long assembly! Also a trailer for storing and transporting jet engines is on display.

One of the Saab Draken exemplars is displayed alongside its engine as well. Interestingly, the afterburner pipe has been separated from the engine core in this case, allowing to check their respective size.

Another interesting item on display in this area, alongside a Bell 47 helicopter with its distinctive bubble canopy, is a Saab J32 Lansen. Primarily built as a fighter and entering service in the 1950s, the career of the Lansen stretched to the 1990s, and saw it employed in several roles, including as a trainer. Interestingly, the study for a dedicated engine – the STAL Dovern – was started alongside with that for the airframe, as typical to other military programs especially in the US. The engine, which reached the flight testing phase, is displayed alongside the aircraft. It represents one of the few projects of the Swedish company STAL for aviation. The company has been for long a primary manufacturer of turbines for electric power plants, started in the early 20th century on the remarkable Ljungström design (the homonym brothers actually founded STAL). In the end, the Lansen employed the British Rolls-Royce Avon.

A well-stuffed display is that of on-board radar equipment employed on the SAAB aircraft in service with the Swedish Air Force.

Among the many design and procurement programs of the Swedish military, special attention was given to missiles. The Robot 08 A, an anti-ship cruise missile employed on destroyers and from coastal batteries in Sweden, was the result of a collaborative program with the French. After a boost phase employing rockets, the efficient small jet engine employed for thrust in cruise (a Turbomeca Marbore) allowed the missile to travel at transonic speed, delivering a warhead up to 100 nautical miles away from the launch site. Navigation was through radio control, and homing on target was radar-assisted.

A real work-horse both in the US and abroad (see this post), a Cessna 337 Skymaster in service with the Coast Guard of Sweden can be found in apparently pristine conditions.

A wing of the museum is dedicated to the collection of the Aviation Veteran Society of Göteborg. Among their many interesting projects is the restoration of classic models, often times unique exemplars from an age prior to the introduction of jets. Each of the aircraft on display in their collection, which is always evolving, has a story to tell. For example, one of them, a British De Havilland Gipsy Moth, was employed by his owner (the Swede Gösta Fraenkel) in the 1930s for an experimental treatment of whooping cough, an infectious disease typically developing in children. The pilot took infected people on board the open-cockpit biplane, allowing cold, dry and clean air to ram into their respiratory channels and lungs for some minutes while flying at a sufficient altitude. Apparently, this treatment accelerated recovery in a percentage of cases. Another aircraft in this area is a SAAB 91A Safir. The ‘A’ version is the original and oldest of this light basic trainer and multipurpose aircraft, dating back to the 1940s, and a good commercial success for Sweden.

Another rich collection is based on an impressive archive of Cold War files documenting many Soviet activities in the territory of the German Democratic Republic. This exhibition (a topic often touched on this website, see for instance here and here) is especially interesting for its completeness and for the level of detail – most files show photographs and numerical data.

A nice array of models, often portraying in dioramas scenes from the real aviation history of Sweden or the region of the Baltic sea, is aligned along a wall. Among them, you can see the first ever defection of a MiG to the West on the Danish island of Bornholm (see this post), as well as the grounding of a Douglas DC-3 in Swedish markings by a MiG-15 which had taken off from Estonia (at that time within the borders of the Soviet Union). That DC-3 has been savaged from the bottom of the Baltic Sea years later, and it is now on display at the museum of the Swedish Air Force in Linköping.

Even if you don’t need it, you should take a detour to the toilet, to access an original corridor and have a look to two full-scale reconstructions of STRIL command centers.

Back outside, you can climb uphill to check out a few additional military vehicles on display, including an exemplar of the highly-succesful line of bi-modular track vehicles called Bandvagn, made by the Swedish company Hägglunds in tons of variants and for different roles. Basically unstoppable on any terrain (and actually working in shallow waters as well), this highly versatile machine is here displayed in a Swedish Army camo paint. Also on display is a rather rare moving lounge, a vehicle for easing boarding operation on larger aircraft. Made by Chrysler in the US (and reportedly employed at Dulles Airport in Washington, D.C., back then), this exemplar was in use at Göteborg Landsvetter airport, before the terminal was re-designed for a better management of passenger traffic.

From the hilltop, you may get a vantage view of the airfield, now the general aviation airport of Säve.

Getting there and visiting

The exact address of Aeroseum is Nya Bergets Väg 50, 41746 Göteborg, Sweden. The location is easily reachable along Hisingsleden, taking north from Göteborg, and connecting some of the premises of the huge Volvo factory quartered north of town. From the crossing with Flygflottilijens Väg (where a bus stop is), it is a .4 miles stretch to the museum’s gate. Huge parking on site. Visiting for technically-minded people with an interest for aviation can easily take 3 hours (4 in my case), checking out all the nice exhibits. There is a self-service restaurant at the bottom of the bunker, as well as a nice shop. Entertaining activities for the kids are on the menu as well.

Together with the Air Force Museum in Linköping, this is possibly one of the top air museums in Sweden, well worth a dedicated trip also for the special construction where it is located. Website with full information (also in English) here.

Maritiman – Göteborg

Located in downtown Göteborg, this museum has on display a handful of vessels, originally employed in Sweden in either civilian or military roles. The most sizable of them, the destroyer Småland (J19), is also an illustrious witness of the Cold War, and a lone survivor of the Royal Swedish Navy of that era. She was built by Eriksbergs shipbuilding company in Göteborg, a now defunct primary player in the Swedish naval history, and it saw service between 1956 and 1979 together with the only sister ship Halland, which gave name to the class.

The neutrality of Sweden for the Navy meant that the fleet of the kingdom was developed with self-defense in mind. At the end of WWII, two cruisers were laid down, Tre Kronor and Göta Lejon, which were the largest vessels ever to see service in Sweden. In the 1950s the shipbuilding effort saw the completion of the new destroyers Halland and Småland, which went operating alongside many more destroyer units over the 1950s and 1960s. All these four ships however were the pinnacle of shipbuilding in Sweden in terms tonnage. By the end of the 1950s the last four destroyers of the Östergötland class (lighter than Halland class) had been put into service, and manufacture of either cruisers or destroyers ceased altogether. By the end of the 1960s, the two cruisers were stricken off, and over the 1970s and 1980s many of the destroyers followed. In the high-tech late era of the Cold War, Sweden opted for a larger number of lighter surface ships, in particular corvettes and torpedo boats. The former are represented today by the highly effective Visby class, which constitutes the backbone of the Royal Swedish Navy today.

Of the historical cruiser and destroyer fleet of the Swedish Navy, the Småland is the only surviving unit. In the Maritiman museum, it is possible to board and thoroughly explore this vessel. Among the distinctive construction features, the castle structure runs all along the ship, allowing the crew to operate while keeping inside, so as to avoid exposition to fallout radiation in a nuclear war scenario. Provision for cleaning the outer decks was made with a pressurized water system, running around the castle. Furthermore, material was steel and iron, instead of aluminum, sometimes employed in shipbuilding for saving weight, but more prone to fire damage than heavier steel. The crew was of 250-290 men. The ship went through three modernization programs, and included three fire direction facilities in the castle.

The heavier gun armament of the destroyer is composed of two turrets (one at bow, one at stern) with two 120 mm guns each, and a bow turret with two 57 mm cannon. Additionally, six 40 mm single-barrel anti-aircraft cannons on revolving turrets are placed along the sides of the ship. All guns were made by Bofors in Sweden.

A single 120 mm gun turret was manned by seven men, and could fire 42 rounds per minute, with a range of roughly 12 nautical miles. It could be employed for targeting other ships, aircraft or land installations.

On the side of the 120 mm turrets you can see flare rockets with super intense illuminating power, which were employed for fire direction at night. Fire direction systems evolved over the years, but the task was mainly performed in the castle structure.

The 57 mm gun turret was designed for anti-aircraft operations, with a range of up to 4,000 m, which was roughly 25-30% more than the standard 40 mm anti-aircraft guns. Fire direction was from the castle deck or locally by the designated gunner.

For anti-submarine war operations, Småland has revolving torpedo tubes on the deck, for the Torped 61 torpedo series, a highly-successful design from Sweden, employed also by foreign customers (see this post).

Additionally, to the bow are two racks of launchers for four anti-submarine rockets each. An example of the body of a Bofors 375 mm anti-submarine rocket is on display beside the rocket launchers. It took 40 seconds to reload one launcher. Fire direction and timing was performed from inside the sonar room, or from a control station beneath the launchers.

The ship could carry out mine laying operations. To the stern of the ship some sea mines are on display on the rail employed for launching them outboard.

The Småland could manage helicopter landings on its deck, and it had the ability to launch anti-shipping cruise missiles. This rather innovative solution for the time was based on the Robot 08 platform (see also the Aeroseum exhibition here in this chapter). Two of them could be carried on the launching pad, where further missiles were stored under deck, and a special incline was employed to take them to the outer deck level for launch. Launch was managed with a dedicated fire control computer.

The Småland could operate as a flotilla capital ship, thus navigation and communication systems were particularly modern and capable on this ship, for the time. Digital computers, with pre-defined communications which could be issued at quick pace, are part of the scenery on the top decks of the castle structure.

The crew compartments, even those for higher-ranking staff, and many technical rooms are as cramped as usual on military ships, not so far from their WWII predecessors.

On top of the castle, the command deck can be found, and from here you can get also a nice view of the town of Göteborg.

Among the most interesting parts, is the engine and power supply area. The Småland was pushed by two independent boiler/turbine systems, which gave power to two propellers. Top speed was 37 knots, and at that speed the ship employed 420 liters of fuel per minute!

The engines required 16 men for operations initially, working close to the hot ducts and parts of the engine at extreme noise level. At a later stage, control rooms were installed in the engine compartments, allowing to reduce the workload and increase comfort to a reasonable level. Filtering and shielding was installed on the air intake system, to reduce the effect of nuclear fallout ingestion by the combustion system.

This area can be toured extensively, unveiling many narrow passages and showing the complex structure of the energy plant, producing power for motion and for all the other onboard systems.

Another highlight of the Maritiman is the Draken class submarine Nordkaparen (Nor, in the registry). The six ships of this class were manufactured in the early 1960s, Nordkaparen (laid down by Kockums at Malmö) entering service in 1962, to be stricken off in 1988. The Royal Swedish Navy has always invested much in its submarine fleet, especially along the entire span of the Cold War, with more than 20 units manufactured post-WWII and before 1989. New models have been introduced after the end of the Soviet Union and the Cold War, and currently four modern units are in service.

The Draken class, propelled by Diesel-electric propulsion, was introduced as an improvement of the older Hajen class, with a single slow rotating propeller instead of two, and a modified stern part and control surfaces. With an operative depth of 150 m and manned by 36 men, it was capable of a top speed of 22 knots submerged.

At the Maritiman it is possible to board the Nordkaparen from the stern hatch, and have a complete tour of its well preserved interiors, coming out from the hatch to the bow.

The rear compartment with the electric motors and a sleeping area for the crew is relatively roomy. Conversely, the center section of the submarine allows only a narrow passage between the Diesel engines, with round tight doors which require some body flexibility to go through!

The navigation deck and the cockpit are again somewhat roomier than their WWII counterparts, similar to the forward compartment, with a reasonable area for the crew.

A unique feature of this design is the revolving rack for storing the torpedoes. Torpedo tubes are four, and all placed to the bow of the ship. The revolving rack, resembling that of a giant revolver, hosts eight torpedoes. It is itself loaded from the back, and it can pivot around its axis pushed by a motor, putting a torpedo in the revolver at the level of the firing tube to be reloaded, thus allowing a faster recharging of any firing tube.

Another military boat from the Cold War years on display is the patrol boat Hugin (P151). A fleet of many, lighter vessels was preferred by military planners in Sweden to one of heavier and more expensive ships with greater firepower, especially towards the last decades of the Cold War. Hugin was the first of her class, and it was manufactured in Norway (Bergen Mekaniske Verksted). Sixteen units of this class were in service in the 1980s with the Royal Swedish Navy.

The boat features a steel hull, and is pushed by two 20-cylinders MB518D Diesel engines made by MTU, delivering a power of 3,500 hp each, and giving this boat a top speed of 39 knots. The crew of twenty men could operate for more days in a row on board the ship. This versatile fast boat was armed with inertial-guided and IR-homed anti-shipping missiles (type Robot 12 Mk 2, made in Sweden), depth charges and ASW-600 Elma grenades (made by SAAB in Sweden) for anti-submarine warfare, and sea mines for mine laying missions.

Additionally, the boat has a single Bofors 57 mm cannon for anti-aircraft gunnery. One of the versions of the Arte fire control system made by Philips was installed on the ship, allowing to engage more targets simultaneously.

The Maritiman has on display a number of other boats, covering a range of uses and a big part of the storyline of shipbuilding in Sweden. Among them are fire-fighting vessels, tugboats, as well passenger commuters.

Getting there and visiting

A top attraction of Göteborg, the Maritiman museum can be reached with a nice walk from the historical city center, simply reaching the water bank from it. The museum will be very entertaining for children, but it has even more to tell to technically minded people. Many detailed descriptions in multiple languages all along the visiting path allow to get much from your visit. Furthermore, the majority of the compartments are open or visible on the Småland ship, all on the Nordkaparen, allowing to fully explore these vessels or look into the many technical rooms. A thorough visit may take about 2-3 hours or more, depending on your level of interest.

The exact address is Packhusplatsen 12, 411 13 Göteborg. Parking options nearby (public at a fee). Website with full access information (also in English) 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.

West of the village along Töntintie road – very narrow and unprepared – it is possible to find a small Soviet monument to war prisoners interned in a local prison camp.

Another preserved bunker can be found right in the center of the nice village of Puumala, along road Pappilantie. The bunker is basically unaccessible, but very easy to walk around. In a receptacle besides the main entrance there is also a Soviet anti-tank gun, probably captured by the Finnish army.

General Mannerheim Headquarters and Communication Bunker

Among the highlights of the lively town of Mikkeli, you can visit here the preserved headquarters of the Finnish Army. The office of General Mannerheim and other top-ranking military staff, plus a fully equipped ‘op-center’, were installed in a local children school. Today a few rooms, including one with many original maps and Mannerheim’s personal office, are the ‘main course’ of the museum, and can be visited.

There are also informative panels, many pictures and some memorabilia belonging to General Mannerheim.

Almost cross the the road from the entrance of the headquarters, you can find another strictly related museum. It is a cave were the communication central of the headquarters used to be and work during WWII. This ensured an uninterrupted communication link not only with the Salpa Line but also with all positions on the line of the front. A part of the cave has been carefully refurbished to resemble what it looked like in the years of operation, including much communication hardware from the time, whereas another part has been left empty.

Both museums can be visited according to the respective timetables (website here for the headquarters, here for the cave). Total visiting time for both attractions is about 1.5 hours.

Raikuu Site

Two Salpa Line sites are located close to the small village of Raikuu, both easily reachable driving on reasonably prepared, unpaved roads.

The first is a massive and pretty rare heavy artillery position. There used to be four such positions scattered in the nearby area, two equipped with 299 mm mortars, two with 152 mm naval cannons. This is the only partly refurbished position. The base for the central revolving pinion where the cannon was anchored can be clearly seen, as well as rooms for the cartridges and for artillery troops.

The second is a group of three reinforced concrete bunkers, maintained to a very good condition and different from one another. The first two are a machine gun and an anti-tank cannon bunker respectively. The military equipment has been taken away, but the different shape of the barrel hole and the supporting structure for the machine gun or for the anti-tank cannon make them easily distinguishable. The machine gun bunkers bears traces of camouflage on the front facade.

Some of the original ventilation pipelines are still there, and clear traces of the wooden structures can be seen on the walls.

The last bunker is partly accessible from behind descending along a steep staircase. This bunker is leaning on the side of a rock, and is well deceived in the bushes.

The site is completed by an anti-tank wall of unusual construction, made of smaller stones put together to a very big overall thickness.

This site is very nice to visit, it is pretty remote so probably you will stay alone and undisturbed. Total time for visiting both including transfer by car may be 1.5 hours if you want to take pictures, or much less if you just want to have a look around.

Joensuu Bunker Museum, Joensuu

The museum in Joensuu is somewhat smaller than those in Virolahti and Miehikkälä (above), and when I visited it was already closed for the season – in mid-August! The good news is that in case you find it closed, you will miss only a visit to the inside of the bunker, pretty standard and similar to those you can see also elsewhere, whereas the outside can be toured for free at any time.

The first sights are two Model 1877, 90 mm French field cannons provided in a number during the Winter War and extensively used in the following years. Close by there are some steel turrets for protecting dugouts to form armored machine gun nests. These turrets, similar to those you may see also in some other Salpa Line sites, were supplied in very limited numbers and were produced in two shapes – you find both here – and three different weights. Those presented here are all intermediate-weight exemplars, weighing more than 5 and almost 8 tonnes respectively for the round shaped and the two-lobed model. The thickness is incredible, and these turrets could withstand a direct hit of a 45 mm anti-tank gun!

On the perimeter there is a Soviet 45 mm anti-tank cannon in a wooden open-top field fortification.

There are two concrete bunkers, put side by side on a promontory. One is equipped with both an anti-tank and a machine gun, the other only with a machine gun.

There are also well preserved dugouts and a line of rocky anti-tank obstacles.

The site is easy to access, with free parking, and compact in size, so less than 1 hour is needed for a visit if the inside is not accessible. Some opening info here.

Huhmarisvaara Artillery Position

Many cannons of French design can be found scattered over the Finnish territory. Except relatively few offered by the French at the beginning of WWII before France was conquered by the German Wehrmacht, the majority are actually Russian cannons from before the the Revolution. When turmoil started to spread in Russia in 1917 leading to the anticipate end of WWI, Finland took the initiative and declared independence from the agonizing empire. As a result, many weapons and military stuff stationed over the territory of the newly constituted Nation were recycled by the Finnish Army.

Many such cannons were later to be placed in the fortifications of the Salpa Line. In Huhmarisvaara, roughly 13 miles north of Joensuu, a concrete fortification for a number of cannons was prepared on a vantage position overlooking a local lake. One of the three Russian-made Model 1892, 152 mm cannons remaining in Finland can still be found in this location.

Vanntajankannas Site

The northern part of the front saw an active participation of the German Wehrmacht in the years of the Continuation War. Possibly one of the northernmost heavy installations of the Salpa Line was located about 5 miles southeast of the town of Kuusamo, close to the administrative border with the Lapland district. The Germans – with the forces of the Organization Todt – built also a railway line about 85 miles long in a north-south direction, with the northern terminal in Kuusamo. The railway helped to supply the army groups operating locally.

The history of this installation, today preserved as an open-air museum with a well maintained walking trail about 3 miles long, is a bit different from others. Soon after the armistice which drove Finland out of the war with the USSR, the German forces, which had to be expelled from the Country, started retreating north towards occupied Norway. They found shelter in the fortifications of the Vanntajankannas site for a few weeks, before loosing them to the Red Army. Soviet soldiers were forced to leave by the end of 1944 in accordance with the armistice agreement, but they blew up every hardware in the Vanntajankannas area before retreating to the USSR.

What can be seen here is what remains of some big concrete bunkers, of the types you can find elsewhere along the Salpa Line. The remains of the bunkers are scattered along the trail. Close to the trailhead there are also scant remains of the local railway station along the German-built line going to Kuusamo.

The anti-tank line of stones is still clearly visible. In many points the trenches, open-top passages and soft machine gun nests have been refurbished to look like the early Forties when they were built.

In the most remote part of the site it is possible to spot remains of the original concrete preparation station, used to supply the construction works, and a small concrete sauna for workers and troops – not really welcoming in these days!

This site is very nice not only for war history but also for the beautiful landscape, with incredible colors. You can also experience a walk over the marshes typical of this region of Finland. The trail is easy, there is a small free parking nearby the trailhead. I would recommend about 1-1.5 hours to enjoy the hiking trail and taking pictures of both the landscape,  the destroyed forts and preserved trenches.

Harparskog Line, Hanko Peninsula

The southern branch of the Salpa Line, also known as Harparskog Line, is composed of a group of bunkers concentrated in the small area around the village of Harparskog – on the Hanko peninsula -, which found itself on the border with the USSR for the first time following the peace treaty ending the Winter War. The annexation of Estonia to the USSR and the control of the Hanko peninsula gave the Soviets the control of the Gulf of Finland, which culminated in Leningrad to the east.

Hanko was evacuated by the Soviets in late 1941 during the victorious phase of the Continuation War.

Similarly to the rest of the Salpa Line, the smaller line in Harparskog featured all types of heavy concrete bunkers, plus dugouts, field fortifications and trenches. Today you can find at least one of the bunkers preserved as a local small museum, plus plenty of barely maintained but mainly accessible bunkers, stripped of most military hardware but still in a very good condition.

The bunker museum was closed when I visited, so here you have a view of the outside only.

Some of the accessible bunkers are aligned along an unpaved road towards the northern shore of the peninsula, north of the village. A commemoration stone with an explanatory panel clearly marks the trailhead.

Besides some more standard bunkers, it is possible to find here a big assembly composed by at least two large bunkers excavated in the stone. The passages leading to the entrances are carved deep in a local cliff, resulting in a very suggestive fort, a mix of natural and artificial defensive positions. Inside this fort it is possible to see also an original stove, ventilation ducts and an air pump.

Further on you can find an anti-tank line, and also a larger deposit and a cave – unfortunately closed.

Exploring this area can be very rewarding, due to the tranquil location and the beautiful, wild natural landscape.

There is much more to see in the area, and for a complete exploration I would suggest about 5-6 hours. The sector to cover is not large and for some parts you can move with a car, but the concentration of material is unusually high and well preserved. If you elect to concentrate only on a part of the line, the necessary time may drop to 1-2 hours for getting a good idea of the main features of this site and taking some good pictures inside. Don’t forget a tripod and a torchlight, for it’s totally dark inside most bunkers, and you should wear a pair of appropriate shoes, for there are mud deposits on the floor and the terrain around the bunkers is totally uneven.

Hanko Front Museum, Hanko

A museum on the vicissitudes of the Hanko peninsula in the years 1940-41 has been established and recently refurbished. It will show up along the main road connecting Harparskog and Hanko, around 2 miles from Harparskog.

The inside part presents an interesting descriptions of the timeline and facts of the Soviet occupation. There are many interesting artifacts from the time, including everyday hardware, light weapons, propaganda leaflets in Russian, maps and many historic photographs. It is interesting to note that the weapons put in place by the Soviets included huge railway cannons, definitely easier to move compared to fixed installations of similar size.

There is also a room with a collection of heavier weapons.

On the outside there are some reconstructed trenches, a Soviet 45 mm anti-tank gun in a reconstructed field fortification, and some other weapons, especially water mines. Active archeology work is going on in the area, and some recent findings, like pieces of artillery and parts of tanks, could be seen when I visited. A short trail in the trees reveals some dugouts and allows to explore the area nearby the former border. Finally there is a 152 mm coastal gun, reportedly the world’s last of the type with this field mounting.

The museum is not large but very rich, so I would suggest 30 minutes to 1.5 hours for a visit depending on your level of interest. Website here.
