Palazzo della Consulta was designed by the Florentine architect Ferdinando Fuga (1699-1782) and built between 1732 and 1734. Its facade is crowned with the coat of arms of Pope Clement XII (r. 1730-40). The two winged figures are the work of the sculptor Paolo Benaglia (1674-1739).
Palazzo della Consulta was built to house the secretariat of the Sacra Congregazione della Consulta, which served as the main council of state of the Papal States. The entrance is surmounted by the coat of arms of the Royal House of Savoy (the two allegorical statues represent Justice and Religion). From 1871 to 1874, the palazzo was the residence of Prince Umberto I, the son of King Vittorio Emanuele II, and his wife Margherita of Savoy. From 1874 to 1922, it housed the Ministry of Foreign Affairs, and from 1924 to 1953 the Ministry of the Colonies. Since 1955 it has been the seat of the Constitutional Court of Italy.
