History and description

The palace, whose structure dates back to the 15th century, has three floors; however, the façade was almost completely rebuilt in the 17th century: the first order on the ground floor consists of a plinth in stone; the portal, not centred with respect to the façade, is the only surviving element of the old façade and is composed of a mixture of marble and stone from Angera, with some surviving decorations in terracotta.^[1]

On the upper floors, one can note the tympanums broken by figures of shells on the first floor, while the second is decorated with balconcini mixtilinear wrought iron. Inside is the courtyard portico on three sides: these porticoes have cross vaults and are composed of round arches in terracotta resting on Corinthian columns.^[1]

The building became famous for being the headquarters of Mussolini's Federazione Fasci Milanesi: the name of Sansepolcrismo^[2] being derived from the square.
