Sääminginsalo has been said to be the largest true island of Finland (area 1,069 km2/413 sq mi). However, it is not a real island, because it is partly surrounded by an artificial canal. If it is considered as an island, it is the third largest island in a lake in the world.[1] This inland island is located in Southern Savonia region, Eastern Finland and is surrounded by the lake Greater Saimaa (Haukivesi, Puruvesi and Pihlajavesi), and an artificial canal, Raikuun kanava, that was built in 1750s.[2][3] The most famous sight on Sääminginsalo is the Kerimäki Church, the largest wooden church in the world.
Traditionally, Soisalo in the same lake complex has been considered the largest island of Finland, but technically it is not a true island either because the lakes surrounding it are not on the same level.[4]
