The Orthodox Church of Kotka, known also as St. Nicolas church, was built between 1799-1801 under the Russian order. It was designed in accordance with drawings by Jakov Perrin, architect of the St Petersburg Admiralty. The orthodox church is probably the oldest building in Kotka and one of the rare to survive a British bombardment of the town in 1855.
The church was built in Russian Neo-classicism style. Differing from a typical orthodox church in Finland, there are lot of sculptures inside the St. Nicholas Church.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
