Palazzo Colonna is a historic building in the center of Marino, in the Roman Castles area of the Metropolitan City of Rome, Italy. Currently, it houses the municipal headquarters of the municipality of Marino.
The palace was built between the 1630s and the 1720s at the behest of various members of the Colonna family, exploiting the pre-existing structures of a fortification that probably already existed around the 11th century. The original design was entrusted to the architect Antonio da Sangallo the Younger, but the current appearance of the building – still unfinished on two fronts – is due to later interventions by other designers, including Girolamo Rainaldi.
The palace remained the personal property of the Colonna family until 1916, when it was given in perpetual emphyteusis to the City of Marino, which installed the municipal headquarters there. During World War II, the palace was almost completely destroyed by Anglo-American aerial bombardment on February 2, 1944; it had been rebuilt by 1958.
