Eglise Saint-Etienne d'Appeville was formerly dependent on the Abbey of Lessay. It is noted for the its solid style and the uniformity of its construction. It was built in the beginning of the 13th century and is almost unaltered, a nearly perfect expression of Cotentin rural Gothic art. At its centre, a square tower forming the lantern tower and bell tower, topped by a slender spire. Single nave, choir with shallow chevet, prominent transept, sexpartite vaults, 15th century porch.

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.
