Fodor's Expert Review Museo Diocesano

Housed in part of the original cathedral structure, this nine-room museum has an impressive number of large, splendid paintings by native son Luca Signorelli (1445–1523), as well as a delightful Annunciation by Fra Angelico (1387/1400–55). The church was built between 1498 and 1505 and restructured by Giorgio Vasari in 1543. Frescoes depicting sacrifices from the Old Testament by Doceno (1508–56), based on designs by Vasari, line the walls.
