The Haichenbach hilltop castle is located at an altitude of 450 meters above sea level on the ridge that forms the so-called Schlögener Schlinge on the Danube.
The first documented mention of Haichenbach dates back to 1160. At that time, Otto and Wernher de Eichenbach are mentioned as representatives of the ministerial noble family that derived its name from the castle. In 1273, the castle must have burned down for unknown reasons, as Rueger von Haichenbach documented in Schlägl in 1274 that he allowed the use of his forests in exchange for accommodation in the monastery hospital, during the time Haichenbach was being rebuilt.
After 1529 Haichenbach Castle was abandoned. Since 1984, restoration measures have been undertaken by the Working Committee for Homeland Care Hofkirchen; the castle ruins can now be safely visited.
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.
