Fodor's Expert Review San Domenico

Although the Duomo is celebrated as a triumph of 13th-century Gothic architecture, this church, built at about the same time, turned out to be an oversize, hulking brick box that never merited a finishing coat in marble, let alone a graceful facade. Named for the founder of the Dominican order, the church is now more closely associated with St. Catherine of Siena. Just to the right of the entrance is the chapel in which she received the stigmata. On the wall is the only known contemporary portrait of the saint, made in the late 14th century by Andrea Vanni (circa 1332–1414). Farther down is the famous Cappella delle Santa Testa, the church's official shrine.

On either side of the chapel are well-known frescoes by Sodoma (aka Giovanni Antonio Bazzi, 1477–1549) of St. Catherine in Ecstasy. Don't miss the view of the Duomo and town center from the apse-side terrace.
