Schwarzenberg Castle was based on a medieval fortification and together with St. George's Church dominates the scene of the large county town of Schwarzenberg.
The castle was probably founded in the 12th century as a fort and was the original base for the settlement of Schwarzenberg and its vicinity. The former castle was given its present appearance by a conversion into a hunting lodge for the Electorate of Saxony from 1555 to 1558. In 1851-52 its keep and south wing were raised and, in 1875-76, an office building extension was added.
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.
