The partly abandoned rural nucleus Pietra dell’Uso (Castrum Petrae Bizingorum) is perched on a sharp cliff at a creek bottleneck, located within the Montetiffi Alto Uso SCI area, a Site of Community Interest for the presence of numerous places of naturalistic and historical-artistic value. The Church of the Nativity of Mary is located at the top of the spur and its origin probably dates back to the Middle Ages, while the bell tower is from the 18th century. In the locality of Vernano stands the Church of St. Benedict, a small religious monument of medieval origin, dating from the 12th century. Built of tanned stone, it has a characteristic circular apse . The small church is guarded by two gigantic centuries-old oak trees.
