Freundsberg castle in Tyrol was constructed in 1150 by the lords of Freundsberg. Originally the castle consisted out of a single keep, which is still intact up to this date. The chapel next to it was built afterwards in the year 1117. In 1467 the castle was sold to Archduke Sigismund of Austria, who rebuilt the castle and called it Sigismundruh for the duration of his reign.
From 1634–37 on, the castle was remodified as a 'castle church' or Schlosskirche. After passing to several other owners from 1812 on, Castle Freundsberg became a property of the municipality of Schwaz. They restored the castle from 1966 onwards.
Since 1948 is the castle a museum where the history of the city Schwaz and the silver mining industry in this region is documented.
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.
