Øsby Church is a large, white village church, which was remodelled into a Gothic long church. You can see the remains of the original 13th century church at the bottom of the east wall. The current church was built in the 16th century.
The church has large, Gothic windows to the south, giving the church a bright and airy space with four sets of rib vaults. The ribs are decorated in Gothic frescoes, and on the northern wall of the nave there is a fresco of Saint George fighting the dragon. The beautiful carved pulpit dates from 1559.
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.
