Basilica of San Francesco, Siena

San Francesco is a basilica church in Siena, Tuscany, Italy.

It was erected in c. 1228-1255 and later enlarged in the 14th-15th centuries, the original Romanesque edifice being turned into the current large Gothic one.

A eucharistic miracle took place involving communion hosts stolen from the church in 1730, which were later found and remain incorrupted.
