The only surviving example of a "Casa-Torre" (House-Tower) from the Malatesta era, belonging to the Tiberti family. In the late 17th century, it was renovated by Pier Mattia Angeloni and subsequently lost its tower due to a fire in 1797. Notable features include the ironwork of 1658 by Romanino, the staircase, and the frescoes inside by Milani.
