Ehrenhausen Castle is well-preserved three-story and four-wing building from the 12th century. The castle was first mentioned in 1240. The current castle was built by the Eggenberg family in the 16h century. It was one of Austria′s numerous fortifications that secured the South and the East of the country against the Turks.
On the castle hill there is also the mausoleum of Ruprecht von Eggenberg (1546-1611) and his nephew Wolf von Eggenberg which was designed by Italian painter and architect Giovanni Pietro de Pomis.
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.
