The medieval church of Jumkil was originally built in the early 13th century. The vaulting was made in the 16th century and detached bell tower was added in the mid-18th century. There are wooden sculptures and triumphal crucifix from the 16th century. Baptismal font is from the 12th century, made of Gotland sandstone, with many carved motifs, such as the birth of Jesus and the adoration of the Three Wise Men. The medieval murals date from the 15th century.
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.
