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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
