The Westphalian State Museum of Art and Cultural History (LWL-Landesmuseum für Kunst und Kulturgeschichte) houses an sprawling collection of art from the medieval to modern periods. Besides an extensive collection ranging from spätgotik painting and sculpture to the Cranachs, the museum specializes in paintings from the Der Blau Reiter and Die Brücke movements, in particular works by August Macke.
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.
