Škrljevo Castle was first mentioned in written documents dating to 1044. The current building dates to the 15th and 17th centuries with some 19th-century rebuilding. Nationalized building is nowadays empty. Bare witness of its former glory is walled, though totally neglected garden and remnants of a park with old yew and lime trees and in its front.
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.
