The Sanctuary of Santa Maria della Querce (“St Mary of the oak tree”), located at the north west limit of the Fucecchio Marshland, was built up in  1637 – 1639 on a land donated by the Gran duke of Tuscany, following a series of miracles attributed to the image of the Virgin Mary placed on a tree, thus the name of Saint Mary of the oak tree. 

The sanctuary was preceded by the early medieval church of San Nazario abandoned in the 14th century. 

Recently has been discovered a fragment of an epigraph mentioning the presence of the relics of the Twelve Apostles.
