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.
