The Palace on the Isle (Polish: Pałac Na Wyspie), also known as Baths Palace (Polish: Pałac Łazienkowski), is a classicist palace in Warsaw's Royal Baths Park, the city's largest park, occupying over 76 hectares of the city center. From 1674 the property and the nearby Ujazdów Castle belonged to Count Stanisław Herakliusz Lubomirski, who commissioned a Baroque bath house called "Łazienka". In 1766 King Stanisław II Augustus purchased the estate and converted the bathing pavilion into a classicist summer residence. (wikipedia.org)
