Former locations The first Romanian Senate functioned between 1864 and 1869 in a small building, which still exists today on the Calea Șerban Vodă. Once the new building of the University of Bucharest was inaugurated, the Senate moved in a bigger hall in that building. Between 1929 and 1940, it was temporarily housed in a building on the Regina Elisabeta Boulevard, while a new Palace of the Senate was to be built in today's Națiunile Unite Square. This building was never finished. After the Romanian Revolution of 1989, the Senate was housed in the "Palace of the Senate" (), located in Revolution Square. That U-shaped structure was built from 1938 to 1941 under engineer 's coordination, following the plans of architect Emil Nădejde. It housed the Council of Ministers and from 1958 to 1989 it was the headquarters of the Central Committee of the Romanian Communist Party (PCR). During the Revolution, Romanian President Nicolae Ceaușescu and his wife Elena fled by helicopter from the roof of the building. In 2005 the senators moved into the Palace of the Parliament, joining their colleagues from the Chamber of Deputies. "Palatul Senatului" now houses the Ministry of Internal Affairs.
