Mühltroff castle was probably in the 10th to 11th centuries to strengthen the rule of German Emperor, the knights to protect against attacks by the Sorbs with their fixings mortgaged founded. In 1357 the Plauen bailiffs had to hand over the castle to the Wettin margrave brothers Balthasar and Wilhelm , who then enfeoffed various vassal families with it. In 1380 the castle was burned down in the Guttenberg feud.
From 1949 to 1989, the castle, which was made public property of the GDR , was used as a residential building until it came back into Mühltroff's possession after the fall of the Berlin Wall. It was sold privately in 1999 as the only part of the castle and contains modern apartments.
As the cultural center of the place, the castle, which can be visited during guided tours, offers rooms for a wide range of club and exhibition activities as well as a wide range of events, with the 'black kitchen' being particularly worthy of mention.
The castle was founded as a low castle on a green stone cliff as a round defense and watch tower surrounded by moats , around which residential and farm buildings and a manor were built over the centuries.
The main building of the castle dates from the 16th and 17th centuries, when a lot was built. Remodeling took place after the fire in 1817 and the castle tower was redesigned between 1820 and 1837 and 1856.
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.
