Savilahti stone sacristy was originally a part of Savilahti church, which was destroyed for some reason. The sacristy was built approximately in 1520-1560 and it was planned to be the first part of new stone church. The plan was never finished because the King of Sweden confiscated parish during Reformation.
The sacristy have been used for burials and there are 22 graves under the floor. It was abandoded for a long time until renovations in 19th and 20th centuries. The sacristy is considered to be one of the oldest buildings in Savonia area.
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.
