 The 13th-century interiors were redecorated in the 17th and early 18th centuries, which removed the altarpieces by masters such as Botticelli, Perugino, Lorenzo di Credi, Domenico Ghirlandaio, and Raffaellino del Garbo.They were replaced by new ones from minor masters such as Carlo Portelli, Alfonso Boschi, Domenico Puligo, Santi di Tito, and Francesco Curradi.In the chapter house is a fresco divided into three lunettes of the "Crucifixion and Saints" (1493–96) by Pietro Perugino, commissioned by Dionisio and Giovanna Pucci.
