The oldest parts of Västa Tunhem Church date from the 12th century, but it has been rebuilt several times. It was enlarged in the 15th century and again in 1736-1740. The current tower was added in 1810. The font dates from the 13th century and pulpit from 1654. The altar and roof paintings were made in 1740-1755.
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.
