The church, built in late Renaissance style, features a high dome divided in coffers, with lantern and a drum. Such a caisson ceiling is a feature of Renaissance architecture. The plan is a Greek cross one, with nave and transepts of the same length, inspired by the church of Sant'Eligio degli Orefici in Rome, one of the few churches designed and built by Raphael. The church is decorated with frescoes by Cesare Sermei and Giacomo Giorgetti (17th century).
