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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
