Bolków Castle is located in Bolków on the Castle Hill (Wzgórze Zamkowe), with a 396 metres, where the hillside is cut by the Nysa Szalona river, with a sharp precipice (with a sudden drop of 90 metres); the eastern side of the hill gradually lowers, taken up by the town. The castle is an upland stronghold, covering an area of 7600 m².
First mentions of the castle come from 1277, from the time of the reign of Boles³aw II Rogatka, Duke of Legnica. The castle's current shape was only done so by various constructions in the sixteenth century, the famous Silesian architect Jakub Parr brought elements of the Renaissance into the castle's fortifications. After the construction and expansion, the castle had a total area of 7600 m², making it one of the largest castles in Silesia. In 1703, the castle in Bolków was bought by Cistercian monks from Krzeszów. After the laicisation of monastic property, the castle went to the State Treasury of Poland.
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.
