The people of Savonlinna had to go to the Sääminki church when they didn't have their own church. In 1850 governor Aleksander Thesleff gave order to build a church in Savonniemi. The actual construction began in 1874.
In 1896 the new Diocese of Savonlinna was founded and the Savonlinna church became a cathedral. The first bishop was Gustaf Johansson. In 1925 the bishop's seat was moved to Vyborg, but the church still retained "cathedral" as its name.
During the Winter War on 1 May 1940, Savonlinna was bombed and the church was damaged. It was restored in 1947–1948 by architect Bertel Liljeqvist. In 1990–1991, it was renovated by Ansu Ånström.
