Baldenau Castle was built by the Trier Elector and Archbishop Balduin of Luxemburg around the year 1320. Initially designed as a hunting lodge, it was later on, beginning in 1324, completed to a residential seat through the construction of additional buildings, stables, and barns. The principal Balduin who initiated the building and gave it his name, was born in 1285 as the youngest son of Count Henry VI. of Luxemburg.
The most impressive part of castle is the keep, 25m height and 10m width. The surrounding moat is 12m wide. During the Thirty Years' War (1618-1648), Baldenau Castle was seriously damaged by Swedish troops, but reconstructed throughout the years 1649-1654. However, only 35 years later, in 1689, the French army devastated 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.
