Gann Church was built in the middle of the 13th century in the locality of Lärbro. The church consists of a chancel, nave and tower. The tower rests on the west wall of the nave. The tower was presumably built in the late 13th century. The church was presumably abandoned as early as in the 16th century. The chancel and arch contain mural paintings.
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.
