Santa Maria in Provenzano, or the Insigne Collegiata di Santa Maria in Provenzano, is a late-Renaissance-Baroque style, Roman Catholic, collegiate church in Piazza Provenzano Salvani, in the Terza Camollia, just southwest of the basilica of San Francesco, in the city of Siena, region of Tuscany, Italy. This Marian shrine was built around a 14th-century terracotta icon of the Madonna, which was credited with miracles. The Palio of Siena takes place on the day of veneration of this Marian devotion.
