Oświęcim Castle (Polish: Zamek w Oświęcimiu) is a castle raised in the Medieval Ages on the top of a hill, on the right bank of the River Soła in Oświęcim. The castle compromises a thirteenth-century early-Gothic defence tower covered by a roof, a two-floor building built around a courtyard (with the old wing from the beginning of the sixteenth century) and additional connections between the wings built in 1929–31. Most of the fortifications around the castle were destroyed due to the changing river course of the River Soła.
