Basilica Cateriniana San Domenico is a vast brick Gothic church at Piazza San Domenico 1, 53100 Siena, on the Camporegio hill northwest of the historic center. Dominican friars began it in 1226, and it was enlarged through the 14th century. Travelers come for its links to Saint Catherine of Siena, Patron Saint of Italy since 1939, whose relics, including her head, are kept in a frescoed chapel. The church also gives a famous view across to the Duomo.
What to Expect at Basilica Cateriniana San Domenico
The exterior is stark, buttressed brick in the Severe Gothic style favored by the mendicant orders, with a square bell tower. Inside is a single, barn-like nave with an open timber roof and a raised transept. The plain space contrasts with the color of the side chapels. Near the entrance, the raised Cappella delle Volte marks the place where Catherine prayed and received her Dominican habit. There you can see the only portrait of her painted from life, by her contemporary Andrea Vanni.
Midway along the right side is the Chapel of Saint Catherine, decorated in 1526 by Il Sodoma. His frescoes of the saint in ecstasy and fainting are among the finest High Renaissance works in Siena. A marble tabernacle on the altar holds her head, and a reliquary nearby holds her thumb. A bookshop run inside the basilica sells biographies and writings of Catherine in several languages, art books, and sacred music CDs.
