The Buurkerk is a former medieval parish church. It is documented as being burned in in 1131, 1173, 1253 and 1279. The tower dates from 1370, but was never finished. In 1577 a cannon was installed in the church tower, aimed at Vredenburg (castle) where the Spanish soldiers there were under siege by the Utrecht schutters. Around 1580 the church endured the protestant reformation and in 1586 it was formally handed over to the protestants, who whitewashed the wall decorations and removed the choir to make room for a street. In 1975 the church fell into disuse and in 1984 it became a museum.
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.
