The Basilica of San Domenico is a large Dominican church in Siena, Tuscany, dating mainly from the 13th century. It is constructed in a sober brick Gothic style and is closely associated with Saint Catherine of Siena.
Interior highlights include a spacious nave, several side chapels, and the Cappella di Santa Caterina, which is a focal point for pilgrims and contains relics associated with Saint Catherine. The basilica’s design reflects the needs of the Dominican order for preaching and communal worship.
