The original Husen castle, documented for the first time in 1246, was probably built here by the dukes of Zähringen in the 12th century. It given into the possession of the counts of Freiburg. In 1303, the castle went to the counts of Fürstenberg as a result of the marriage of Verena of Freiburg.
Count Henry IV of Fürstenberg had the castle extensively remodelled and expanded from 1453 to 1477. A neck ditch and an outer ward guarded the actual castle with its palas and bergfried.
The castle was the residence of the prince’s castellans (Burgvögte). In 1632 it burned down and was rebuilt. In 1643 French-Weimar troops under Jean Baptiste Budes de Guébriant destroyed the castle.
Later the ruins were incorporated into fortified earthworks or schanzen in order to defend the valley against enemy troops. In 1896 the bergfried was given battlements instead of the tower’s conical roof. In 1968 the town of Hausach purchased the ruins from the House of Fürstenberg. Today, parts of the palas wall, the so-called battery tower and the bergfried survive.
References: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.
