Suomenlinna Sea Fortress

Suomenlinna Fortress (Swedish: Sveaborg – "Swedish Fortress") was founded in 1748 when Finland was part of the Swedish Kingdom. After its defeat in the Great Northern War, Sweden lost its eastern territories, and a powerful sea fortress was needed to protect Helsinki from the sea. The initiator and "father" of the fortress was Swedish Field Marshal Augustin Ehrensvärd, whose monument stands on the central square.
