The building dates from the 15th century, and the collection is displayed in one of its two cloisters and in the Chapterhouse. The complex restoration permitted the fusing of these two collections into one exhibit which also connects to the Church of Saints Filippo and Giacomo where a multimedia station is planned. The result is large, coherent exhibit which presents the development of local artistic development from the Middle Ages to the 1900s, with a focus on Sienese painting represented by masters like Bartolo di Fredi, Simone Martini, Ambrogio Lorenzetti, Giovanni di Paolo, Sano di Pietro and even a local painter and photographer, Arturo Luciani.
Amongst the art works which have been recently restored are a number of painted wood sculptures which, during the Middle Ages, were used for liturgic purposes, and were made by some of the most important artists of that time, including Jacopo della Quercia and Francesco di Valdambrino. The Crucifixion by Giambologna is just one of the masterpieces of the collection, displayed with medieval ceramics, textiles, jewellery and illuminations.
