Ujazdów Castle (Polish: Zamek Ujazdowski) is a castle in the historic Ujazdów district, between Ujazdów Park (Park Ujazdowski) and the Royal Baths Park (Łazienki Królewskie), in Warsaw, Poland. Its beginnings date to 13th century, and it was rebuild several times. Like many structures in Warsaw, it sustained much damage in the Warsaw Uprising. Reconstructed after the war, it now houses the Warsaw's Center for Contemporary Art.
