In 1910 during the restoration of Angerdshestra church 30 old pergaments were found revealing that the old church was inaugurated in the 13th century. Today documents are located in Stockholm Historical Museum. The current church was made of wood in 1669 to the site of medieval church. It was enlarged and restored in the 18th century. The oldest artefact is a wooden sculpture of St. Anne, dating from the 15th century. The altar was probably painted by Johan Kinnerus between 1716-1717.

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.
