Beside the facade of the church of Santo Spirito, one of the last works of Filippo Brunelleschi who left it unfinished at his death in 1446, is the entrance of the old refectory of the Agostinians. This large, truss-vaulted room belonged to the oldest part of the monastery, dating from the fourteenth century. This refectory has its end wall frescoed, in the traditional way, by Andrea Orcagna and his brother Nardo di Cione with the Crucifixion above and a very damaged Last Supper below. Since 1946 the room has housed the collection of the Salvatore Romano Foundation, an important antique dealer who left it to the Town Council. It consists mostly of sculpture, among which the most valuable pieces are an Angel by Tino di Camaino (l280-c. 1337), a Madonna attributed to Jacopo della Quercia (1371-1430) and fragments of the altar of the Santo at Padua attributed to Donatello together with Byzantine and pre-Roman pieces.
