The oldest known church on the site was built in the 13th century. The medieval church was demolished in 1854 and replaced with a new one designed by Sven Sjöholm and J. A. Hawerman. This church was destroyed by lightning in 1943. The present church was built in 1946-1947.
The medieval font and altarpiece (painted in the mid-19th century) have survived. The other interior date from 1940s.
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.
