Suomenlinna Church
The Suomenlinna Church (Finnish: Suomenlinnan kirkko, Swedish: Sveaborgs kyrka) in Helsinki, Finland, was built in 1854 as an Eastern Orthodox garrison church for the Russian troops stationed at the Suomenlinna sea fortress. The fortress comprises five islands joined by bridges, and the church is the central feature on the island of Iso Mustasaari (Swedish: Stora Östersvartö), located at its highest point.
