The oldest parts of Mörbylånga Church were built in the 13th century. For instance the decorations over the west tower portal have been dated to this period. The church was enlarged and reconstructed in the beginning of 19th century according the design of Johan Petterson. The medieval tower was restored in 1872.
The church possesses a triumphal crucifix, which would have been used in procession during medieval times, from the same period. The porch contains a tombstone from the fourteenth century. The pulpit, by Anders Dahlstrom, was carved in 1747.
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.
