Among the most valuable works are a “Maestà”, the name given to images of the Madonna and Child surrounded by angels and saints, attributed to Giotto from the Palazzo del Capitano del Popolo, a standard by Niccolò di Liberatore known as the Pupil, and the Virgin and Child, detached from the gate of San Giacomo, attributed to the young Perugino. There are also frescoes by Ottaviano Nelli, Andrea and Tiberio d’Assisi, canvases by Dono Doni, Giacomo Giorgetti and Cesare Sermei. Ample space is devoted to the masters of the School of Giotto: one room houses the works of Puccio Capanna, including the valuable Madonna and Child with Saint Francis from Porta San Rufino.
