Glauchau was founded by a colony of Sorbs and Wends, and belonged to the lords of Schönburg as early as the 12th century. Hinterglauchau Renaissance-style castle was built from 1470 on the site of a castle built by the Lords of Schönburg around 1170 and has been the center of their rule for centuries . With the construction of the parts of the building, later called Castle Fordglauchau, the facility was expanded towards the city from around 1525. At the same time the main castle was rebuilt. In the early 20th century a museum was set up in the castle.
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.
