Castle in Oświęcim - a building erected in the Middle Ages on the top of a hill, on the right bank of the Soła river in Oświęcim.
The castle consists of an early gothic bergfried tower built at the end of the 13th century and a two-storey, basement building erected on a rectangular plan (old castle wing from the beginning of the 16th century) and a link from 1929–1931 built on the site of older buildings. A significant part of the fortifications was taken by the river - which changed its course for centuries.
On the castle hill there are remains of defensive walls and bastions. The royal castle was located in the second half of the 16th century in the Silesian poviat of the Kraków voivodeship. There are two tunnels under the castle: the older one (built before 1914) and the other one drilled by the Germans (1940–1944). This tunnel served as an air-raid shelter.
The first mentions of the Oświęcim castellany come from the period when it was incorporated into the Duchy of Opole (1177–1179). The reconstruction and fortification of the castle are attributed to the son of Mieszko Plątonogi, Prince Kazimierz. This is evidenced by archaeological discoveries near the tower confirming the existence of a brick structure on the castle hill in the first half of the 13th century.
