Divided into three naves, the Collegiate Church of Santa Maria Assunta preserves masterpieces on the walls. On the top of the counter is the Martyrdom of Saint Sebastian by Benozzo Gozzoli while in the central part of the extraordinary Judgement Taddeo di Bartolo. Along the right wall are the Stories of the New Testament, the students of Simone Martini, and on the left Stories of the Old Testament by Bartolo di Fredi.
