Suomenlinna Church, Structure of worship in Suomenlinna, Finland
Suomenlinna Church is a stone building with a plastered grey facade and a square tower, standing on Iso Mustasaari island within the Suomenlinna fortress. The tower rises to about 27 meters (88 ft) and is visible from the sea, making it one of the most recognizable structures on the island.
The building was constructed in 1854 as a Russian Orthodox garrison church with five onion domes, when Suomenlinna was under Russian rule. After Finnish independence, it was converted to a Lutheran church in the 1920s and the domes were replaced by the square tower that stands today.
The church serves the small permanent community living on the island and hosts weddings and concerts open to visitors. During summer, it draws people from the ferries who wander through the fortress and step inside for a moment of stillness.
The tower is visible from the ferry approach, so it is easy to use as a landmark when you first arrive on the island. Opening hours vary between summer and winter, so it is worth checking before you make the trip.
The church tower doubles as an active lighthouse, sending four consecutive light flashes that represent the letter H in maritime signaling, standing for Helsinki. It is one of very few church towers in the world that also serves as an official aid to navigation.
