Sea Fortress Suomenlinna
The Sea fortress Suomenlinna/ Viapori (Sveaborg in Swedish) is a unique architectural monument, a popular recreation area and museum, and at the same time a living community. Viapori used to be the biggest fortification in the kingdom of Sweden. It was founded in 1748 and was built as a bastion on six islands off Helsinki by Augustin Ehrensvärd. To begin with, the fortification defended Sweden for 60 years against Russia, but after it was forced to surrender i 1808 it became a Russian fortification for 110 years. In 1855 it was attacked by the British navy.
In 1918 the fortification was renamed Suomenlinna and it acted as a Finnish garrison until it came under civil administration in 1973. In 1991 Unesco included Suomenlinna in the List of World Heritage sites.
Departure of Suomenlinna ferries from the Market Square and Suomenlinna usually once an hour. From the beginning of May through August ferries depart in daytime at shorter intervals, 3–4 times per hour.
