Skepptuna was built of bricks and stone in the early 1200s, but it was destroyed by fire around 1300. During the restoration the church was enlarged. The altar screen with medieval paintings is the most valuable artefact in Skepptuna Church. It was done in Brussels and bought to Sweden after 1500. The font dates also from the early 1500s.
References: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.
