The oldest parts of Follingbo Church are the nave and tower. They date from circa 1200 and together form an unusually accomplished example of Romanesque architecture on Gotland. Although lacking in ornamental sculpture, the tower and nave are well-proportioned and unusually professionally executed. The choir is later (late 13th century) and already Gothic in style, and also considered unusual for its kind. The choir replaced an earlier, Romanesque choir with an apse. The current choir instead has a straight eastern wall, adorned with a single tracery window, in which fragments of medieval stained glass panes remain. The sacristy was built in 1820-21.
Inside, the church has a painted ceiling, decorated at the end of the 17th century. Most of the furnishings are also from the 17th or 18th century. An exception is the undecorated baptismal font, which is medieval.
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.
