Žumberk Castle was probably built during the end of the 13th century, on a hilltop above the village, and was known under the German name Sunenberg. Its walls formed a pentagon and were surrounded by a deep moat, with a service yard was placed next to the castle. Later, a township grew up under the hill.
The first known owner of the castle and neighbouring villages was a robber knight; ownership of the castle changed many times afterwards. At the beginning of the 18th century, the castle was not inhabited, though during 1760–70 a physician lived there. The castle became desolate and was left to be a source of construction material.
During 1926–48 the castle was owned by the Club of Czech Tourists, and its structure was stabilized to prevent further destruction. Today the market town of Žumberk is responsible for its maintenance, and access to the castle is unlimited and free.
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.
