Today's Palace is the result of the commission that the brothers Giacomo Francesco and Alessandro Bruno made in 1680 to valent architect cesenate Pier Mattia Angeloni. It is impressive with respect to adjacent historic palaces, characterized by Marble of Pope's Pontifical Coat of Arms. It has a massive structure: the inner facade of the courtyard houses a splendid three-storey loggia with white stone columns framing Malatestian Library. From the stairs you access a loggia decorated by four statues of Francesco Calligari depicting Minerva, Cerere, Gloria and Mars. From here you can access the great Salon of Honor, characterized by pictorial cycle by Giacomo Bolognini, realized between 1719 and 1721.
