Revolution Square is a square in central Bucharest, on Calea Victoriei. Known as Palace Square until 1989, it was later renamed after the 1989 Romanian Revolution. The former Royal Palace (now the National Museum of Art of Romania), the Athenaeum, the Athénée Palace Hotel, the University of Bucharest Library and the Memorial of Rebirth are located here. The square also houses the building of the former Central Committee of the Romanian Communist Party (from where Nicolae Ceaușescu and his wife fled by helicopter on December 22, 1989). In 1990, the building became the seat of the Senate and since 2006 it houses the Ministry of Interior and Administrative Reform.
