Suomenlinna Island Fortress (Helsinki)

Suomenlinna (Swedish: Sveaborg) is a sea fortress located off Helsinki. As a historical monument and attraction, its cultural value is significant, and it is a strong part of Helsinki's identity. The construction of Suomenlinna started in 1748 and until 1918 it was known in Finnish as Viapor, based on its Swedish name Sveaborg. Suomenlinna was added to the UNESCO World Heritage List in 1991. Suomenlinna is a district of Helsinki where about 800 people live.

Suomenlinna is one of the most popular tourist destinations in Finland. In 2019, the fortress was visited by around one million visitors. Suomenlinna organizes various district and cultural events throughout the year. There are many cafes and restaurants located on the islands.

Suomenlinna is renovated and maintained by the Suomenlinna Management Board, which is a state agency under the Ministry of Education and Culture.

Nowadays, the only military institution on the islands is the Naval Academy located in Pikku Mustasaari. Suomenlinna prison, established in 1971, is located at the southern tip of Iso Mustasaari, under the authority of the Criminal Sanctions Department. A key part of the repair work on walls, ramparts and buildings is done as prisoner work. The prison has places for about 100 prisoners.

 

Geography

The bastion fortress is located on six of the eight islands of the Suomenlinna district. The main fortress was made at Susisaari. The southern Susiluoto fortress was named Kustaanmieka in 1749. Smaller islands are Pikku Mustasaari, Länsi-Mustasaari and Särkkä. The largest is Iso Mustasaari. Kustaanmiekka, Susisaari, Iso Mustasaari, Pikku Mustasaari and Länsi-Mustasaari are connected to each other thanks to either a bridge or an isthmus. The strait that once existed between Susisaari and Kustaanmieka has been filled. On the east side of the group formed by these islands is the Kustaanmieka Strait and on the west side the Särkänsalmi, which are the most important shipping lanes leading from the open sea to Helsinki's Kruunuvuorenselka and Eteläsata. Suomenlinna's land area is 2.21 square kilometers.

 

Sights

Suomenlinna is a popular destination for domestic and foreign tourists visiting Helsinki, as well as for Helsinki residents. Suomenlinna is accessible all year round and the fortress is a great place to visit in all seasons. Linnoitusaari has attractions and versatile services, such as guided tours, restaurants, cafes, museums and art exhibitions.

Kuninkaanportti is the gate to Suomenlinna located at the southern tip of Suomenlinna, on the shore of the Kustaanmieka strait. It was originally the primary entrance to the Suomenlinna fortress, and it is generally considered to be the symbol of Suomenlinna. In the years 1986–2002, its image was also on the thousand mark banknote.

The large castle yard in Susisaari with its surrounding buildings is the old administrative center of the fortress. The part left between the bastions Ekeblad and Höpke was transformed in the early 1750s into Finland's first monumental square that applied the principles of late baroque composition. In the middle of the square is the grave of Augustin Ehrensvärd, whose tombstone was laid by Gustavus III himself on July 5, 1783. The granite pave was carved by Nils Stenstam. Some of the buildings surrounding the square were destroyed during the Crimean War artillery fire, but what remained was, for example, the commandant's house, which is now the Ehrensvärd Museum. Linnanpiha is also bordered by Paikallismajur's house, completed in 1756, which is the oldest apartment building in Suomenlinna and all of Helsinki that has been in residential use since the beginning.

Suomenlinna church is located in Iso Mustasaari. It was built between 1850 and 1854 in the Orthodox style with onion towers, but was changed in the 1920s to its current Lutheran appearance. There is a beacon on the church tower that flashes four short flashes, which is H in Morse code for Helsinki.

The museum submarine Vesikko is located at the southeast tip of Susisaari. Vesikko graduated in 1933 and served in the Finnish navy during the winter and continuation wars. You can see Vesikko all year round, and in the summer months you can get to know the interior of the submarine.

Rantakasarmi The pink-plastered Rantakasarmi is the main gate of the fortress built in the Russian period. The facilities at the east end of the beach barracks have a recording studio and work rooms. The premises of the brewery, the restaurant and the gallery of the Helsinki artists' society are located in Länsipäädy.

Kruunulinna Ehrensvärd Kruunulinna Ehrensvärd is an equipment type that consists of two wing buildings and a defensive front between them. King Gustav III of Sweden laid the foundation stone of the Crown Castle in 1775. The Crown Castle protected the shipyard area and the depot, and the shipyard's production and offices were located in its two wings. Nowadays, Kruunulinna Ehrensvärdi houses, among other things, the office of Suomenlinna's nursing board, a daycare center, apartments, and Pirunkirko's banquet hall and Pajasali, which are rented out to the public for parties and meetings.

Bastioni Zander Bastioni Zander has had a fortress flag flying throughout the history of the fortress. Bastion Zander was built between 1748 and 1750 as part of a chain of four bastions.

In addition, Suomenlinna's tunnels are popular, especially in Kustaanmieka and Susisaari.

 

Suomenlinna shipyard

In Suomenlinna, in the northern part of Susisaari, there is a shipyard where warships were originally built. After the Second World War, the shipyard was owned by Valmet, and ships handed over to the Soviet Union as war reparations were built there. The former Suomenlinna and Korkeasaari ferries were also built there. Suomenlinna shipyard is the oldest dry dock in Finland.

Today, the Turkulaisvarustamo Alfons Håkans Oy operates at the Suomenlinna shipyard. The dry dock's larger indoor pool is 140 meters long and 50 meters wide. The smaller outdoor pool is 120 meters long and 20 meters wide. A 5 meter deep channel leads to the dock basins. It is Finland's only dry dock east of Hanko. It mainly repairs ships of the navy and the border guard, but also local ships, tugboats and vessels operating on the Saimaa are being repaired and in winter storage at the shipyard.

 

Transport connections

Suomenlinna is served by the Suomenlinna ferry of Helsinki Region Transport (HSL) from Kauppatori daily throughout the year. You can get to Suomenlinna from Katajanokka by HSL's service ferry on weekdays all year round. HSL's ferries belong to public transport.

During the summer months and autumn, the fortress can also be reached by water buses operated by JT-Line Oy. Tickets for the water buses are bought from JT-Line. The sea journey takes about 15 minutes.

HSL's ferry has worked for e.g. M/S Suomenlinna-Sveaborg built in the 1950s. M/S Suomenlinna II, which replaced the ship, initially had a rather dubious reputation due to numerous small wrecks.

Suomenlinna also has an undersea service tunnel, about 1,300 meters long, where district heating, water and sewer pipes, as well as electricity and telephone cables run. Only emergency vehicles use the service tunnel. The mouth of the tunnel is on the mainland side in Kaivopuisto at the Uunisaari pier, and the end of Suomenlinna is on Länsi-Mustasaari. According to an urban legend, there is also a tunnel from Suomenlinna to the neighboring Vallisaari, but that is not true.

 

History

Construction background
Sweden had suffered a defeat against Russia in the War of the Hats in 1741–1743, and had to give up even more territories in addition to the losses in the Peace of Uusikaupunki in 1721. In the peace of Turku, it lost Kymenlaakso as far as the west branch of Kymijoki and along with it the border fortress of Hamina. The city of Loviisa, founded in 1745 on the lands of Degerby's horse farm, became the frontier town. After the War of the Hats, efforts were made to strengthen Finland's defense so that in the event of a war, there would be time to send reinforcements from Sweden to the region. In 1747, a special fortification commission proposed the construction of fortifications in Loviisa and Helsinki. The purpose was both to fortify the cities and to build sea fortresses in front of them.

Construction work
From Sweden's point of view, the central idea was to have its own coastal fleet for the eastern part of the kingdom and a base for it, because there would not have been time to send ships from Karlskrona or Stockholm to protect the eastern border, especially in the spring when the ice was leaving. Part of the fleet had wintered at Kruunuvuorenselka already at the time of the Great Hatred. France, on the other hand, was worried about the growth of Russian influence and committed to support Sweden's fortification efforts in Finland with 450,000 thalers a year for four years. Construction work on the Suomenlinna and Svartholma sea fortresses planned for Helsinki and Loviisa began in 1748. Augustin Ehrensvärd, a fortress officer born in Västerås, Sweden, was responsible for the design and construction of both fortresses. In addition to the sea fortresses, the planned land fortifications were left badly unfinished due to the kingdom's lack of money and eventually ended completely.

Building material for the areas was obtained at least from Helsinki pitäjä (now Vantaa), Santahamina and Espoo's Souka. However, for the most part, the stones needed to build the walls were mined from the rocks of the islands themselves. The construction of Suomenlinna was never completed to the extent that Ehrensvärd intended. In 1756, an archipelago fleet subordinate to the land forces, Armeija laivasto, was established in Viapori. During Gustav's war, Viapori served as a repair yard for the Archipelago fleet and contributed to the victory of the Battle of Ruotsinsalmi in 1790.

Post office
In 1802, the second post office in the Helsinki region was established in Viapori, which was due to the activities of Carl Olof Cronstedt, who served as the commander of the fortress garrison. Cronstedt was saddened by the disappearance of the navy's letters and pushed through the establishment of a post office despite the opposition of the kingdom's postmaster general. Post office operations ceased in 1808 after the Russians conquered Finland. The Russians revived the postal service in Viapori, which had served military purposes, in the mid-1850s during the Eastern War.

 

The time of Russian rule

At the beginning of the Finnish War in 1808, the Russians arrived in Finland by land and quickly occupied a large part of southern Finland. They also laid siege to Viapor, which they reached from the mainland by ice. After a two-month siege, the fortress led by Cronstedt surrendered on May 3, 1808.

After Finland became part of Russia in 1809, the Russians continued to build the fortress according to their own plans. During Swedish rule, the focus of construction work had been on Susisaari and Kustaanmieka, which are considered the most interesting parts of the fortress in terms of construction history. On the other islands, the fortifications had remained unfinished. During Russian rule, on the other hand, Iso Mustasaari became the central part of the fortress, where, among other things, large barracks and a church were built.

During the Crimean War in 1855, Viapor was shelled by cannons from French and English warships for two days. In this case, part of the original buildings of the fortress were destroyed.

In 1906, the Viapori rebellion broke out in the fortress. Viapori served as the central fortress of Krepost Sveaborg during the First World War. In addition to the land front that surrounded Helsinki, the fortress also included the sea front fortresses, such as Miessaari, Rysäkari and Kuivasaari.

 

The time of Finnish independence

When Finland declared its independence in 1917, Viapori was still in the possession of the Russian military, but during the civil war they handed over part of it to the Finnish Reds in March 1918. The Whites conquered it with the support of the Germans in early April. Suomenlinna got its current name on May 12, 1918, when the red and yellow lion flag temporarily used as the flag of Finland was hoisted in Kustaanmieka's flag vault and eight salute shots were fired with two Russian field cannons. Distinguished guests were invited to the flag-raising ceremony, e.g. members of the senate, the city council and several high-ranking military personnel. They were transported from the market square to the Viapor pier by the pilot ships Eläkö and Sekstant and the icebreaker Mercator. At the same time, the military area was annexed to Uusimaa county. Senator Kyösti Kallio's proposal was behind the name change of the fortress.

In 1918 and 1919, a large post-civil war prison camp operated on the islands. Of the 10,000 Red prisoners in the Suomenlinna prison camp, more than 1,000 died of starvation and disease. There were 80 executed. Later, the fortress served as a Finnish garrison. After the Finnish Civil War, the Suomenlinna Fortification Artillery was established in Suomenlinna on May 7, 1918, under which name the unit's operations ended on September 15, 1918. Due to the organizational reform, the Suomenlinna Coast Artillery Battalion continued its operations from September 16, 1918 to May 13, 1919. Coast Artillery Regiment 1 was established on May 14, 1919, which operated for 15 . until September 1939.

In the 1920s, the Naval Academy was located in Suomenlinna. In the years 1921–1936, the aircraft factory of the Finnish Air Force was located in Suomenlinna. The factory initially assembled under license Hansa-Brandenburg W.33 water levels, known in Finland as I.V.L. A.22 Hansa. In 1925, an air defense command was placed in Suomenlinna, which later turned into a fixed anti-aircraft battery. In 1939, the fixed anti-aircraft battery was changed to the Anti-Aircraft Regiment I. During the Second World War, there was also the main base of Finnish submarines.

Finland's neutrality watch related to the beginning of the Second World War required an increase in defense before the joint exercise. On September 16, 1939, the Helsinki Block was formed, which was valid until September 4, 1940, at the time of the interim peace. From September 5, 1940 to March 27, 1941, the Suomenlinna unit was again Coastal Artillery Regiment 1, after which it became the Suomenlinna Coastal Artillery Regiment from March 28, 1941 to June 16, 1941. In order to prepare for the next war, the unit was also expanded to moderately contain coastal forces as the 1st Coastal Brigade, based on the experience of the winter war of the coastal artillery regiments, on June 17 For the period between 1941 and December 31, 1941, after which it was named Uusimaa Coastal Brigade for the period between January 1, 1942 and November 30, 1944. After this, the unit became the Coastal Fortification of Suomenlinna from December 1, 1944 to November 30, 1952. After that, it was renamed Coastal Artillery Regiment 1 for the third time from December 1, 1952 to December 31, 1956. After this, the mass unit became the Coastal Artillery Regiment of Suomenlinna from January 1, 1957.

Until 1948, you could only get to Suomenlinna with a written landing permit. At that time, the islands were opened to the public for an entrance fee charged by the Finnish Tourist Association, although they were still under the control of the Finnish Defense Forces as a garrison. In 1972, the fortress was finally transferred to civilian administration. The only military institution there remained the Naval Academy. The following year, the Suomenlinna Administration under the Ministry of Education was established to manage the islands.

In 1983, the Suomenlinna administration was awarded the SAFA award for the restoration work of Suomenlinna. In 1991, Unesco added Suomenlinna to its world heritage list. Suomenlinna received the Europa Nostra award for expert and high-quality restoration work in 1999. In the same year, the provincial board of the Uusimaa Federation chose Suomenlinna as Uusimaa village of the year.

 

In the 2016 agglomeration delimitation, Suomenlinna formed its own agglomeration with an area of 0.63 square kilometers. The agglomeration had 748 inhabitants, and with a population density of 1,195 inhabitants/km², it was the fifth most densely populated of the agglomerations in Finland.

In the northwestern part of Iso Mustasaari, there is an archive and museum cave used by the management board.
