Experts believe that the castle dates back to the eighth century. Throughout its history, the castle - located on a wooded hill - has been ruled by several powerful noble families and on various occasions it was ruled by Siena. In 1255, Siena’s domain over the castle was significantly strengthened following its acquisition of this district and the construction of a new quarterdeck. Afterwards, it was managed by the lordship of Montorsaio Salimbeni which dominated the area until 1375. In 1432, a statute was drafted by the community and, in 1559, it was ruled by the Medici family.
