Suomenlinna’s significance in the historical defence of three states – Sweden, Russia and Finland respectively – is of special importance. The sea fortress began construction in 1748 (under Swedish control) directed by military architect Augustin Ehrensvärd and it was a key post in many wars. In 1788 it defended the Swedes from Russia; in the War of Finland, 1808-09, the fortress surrendered to the Russian army and it was active during the Crimean War in 1855 when the British and French allied with Turkey to deprive the Russian Navy of a route to the Baltic Sea and from there to the Atlantic.

In 1856 the Russians started to repair much of the damage and continued to do so under the command of the Tsarist autocracy (looking to safeguard Saint Petersburg) until the Russian revolution in 1917, when Finland also gained its independence. The newly installed government took over the island 1918 to 1973 when the Finnish military transferred selected properties to civil administration via a state body: the Governing Body of Suomenlinna, a branch of the Minister of Education and Culture.

Property guide


In Finland when you own a property you also own the land on which it is built. Property owners become “share holders” in a housing company, paying a monthly sum to cover the costs for maintenance services. Sellers need to pay 1.6 per cent of the sale price to the Finnish government plus a commission fee to the estate agent. In the case of JYA Housing, which is currently dealing with the sale of a 93 sq m flat on the island, this will be 4.3 per cent of the asking price. In 2011 for the first time a broker got involved in the sale of a property in Suomenlinna. Before then if you wanted to buy property you had to go through the military or the close-knit network of families living there.
