The equestrian statue of Frederick the Great is an outdoor sculpture in cast bronze at the east end of Unter den Linden in Berlin, honouring King Frederick II of Prussia. Designed in 1839 by Christian Daniel Rauch and unveiled in 1851, it influenced other monuments. After having been enclosed for protection during World War II, the statue and its base were removed by the East Germans in 1950 and re-erected in 1963 at Sanssouci in Potsdam, but returned to Unter den Linden in 1980. After German reunification the monument was moved back to its original location and restored. It is a registered monument of the City of Berlin.
