It isn’t certain who built the 16th Century Palazzo Bianchini Riccardi. Some attribute it to Antonio da Sangallo the Younger, others to Vongola or even to Bramante. The front has 3 varying framed window lines and beautiful decoration of Angevin lilies, which was a typical choice of the Rosci family to whom the Palace first belonged. Inside are several works of note including a Madonna del Cassero image of the 16th Century, and some remains of a Roman mosaic.
