The Orthodox church of Hamina (The Church of Peter and Paul) was erected in 1832-37 on the place of burned Lutheran church. It was designed by Frenchman Louis Visconti whose most famous work is the tomb of Napoleon in Hôtel des Invalides.
The round-domed church was built in the Neoclassicism style with Byzantine features. There is a holy icon with St.Peter and Paul which was transferred to Hamina from Vyborg in 1742.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
