Mongiovino is a typical Marian sanctuary, and is historically famous for the battle in the 17th century fought between the papal army and that of the Grand Duchy of Tuscany. Originally dedicated to the Madonna of St. Martin, it housed a chapel with a Marian image. The episode that gave rise to the beginning of Mongiovino’s devotional activity took place on an unspecified date around 1500. Many were the stonecutters that decorated the bas-reliefs of the portal arch jambs. The sanctuary was built in sandstone from the nearby quarries of Petraia and Cibottola.
