Fors Church is first time mentioned in 1338. The major restoration occured in 1709 when the new choir was constructed and windows enlarged. The new sacristy was added in 1900. The paintings in ceilings date from 1746, made by Ditloff Ross. The font was made in 1200s, the Baroque pulpit in 1734 and organs in 1954.
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.
