Presidential Palace, Warsaw
The Presidential Palace (in Polish, Pałac Prezydencki; also known as Pałac Koniecpolskich, Lubomirskich, Radziwiłłów, and Pałac Namiestnikowski) in Warsaw, Poland, is the elegant classicist latest version of a building that has stood on the Krakowskie Przedmieście site since 1643. Over the years, it has been rebuilt and remodeled many times. For its first 175 years, the palace was the private property of several aristocratic families. In 1791 it hosted the authors and advocates of the Constitution of May 3, 1791.
It was in 1818 that the palace began its ongoing career as a governmental structure, when it became the seat of the Viceroy of the Polish (Congress) Kingdom under Russian occupation (Namiestnik of the Kingdom of Poland). Following Poland's resurrection after World War I, in 1918, the building was taken over by the newly reconstituted Polish authorities and became the seat of the Council of Ministers. During World War II, it served the country's German occupiers as a Deutsches Haus and survived intact the 1944 Warsaw Uprising. After the war, it resumed its function as seat of the Polish Council of Ministers.
