The Church of Saint-Pierre is of Romanesque origin and contains a renaissance stoup and a Statue on the Virgin in coloured wood. Behind the Altar is the tomb of Jeanne du Peyrer 'Lady of Athos and Aspis' and mother of the musketeer. The renaissance door has a stone carving from the 14th century upside down (it was probably a stone that was reused).
The cemetery has the tomb of the design engineer of the Sauveterre bridge and also that of Edmond Gourlat, consul of France and local personality.
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.
