The part of the municipal territoty curerntly occupied by the district of Chia – about 7 km away from the village – appears to have been inhabited since the pre-Etruscan age as evidenced by several hypogetical constructions, cave tombs, pools and wells scattered around the area. Built on a tuff hill, the defensive design of this building still represents todate, a typical example of medieval urban planning with its narrow paths and small dwellings, often equipped with bastions. In the Middle Ages, this ancient feud was property of the Apostolic Chamber, which later transferred it to numerous families such as; the Orsinis, the Guastapanes, the Colonnas and, in modern times, to the Lante Della Rovere ed Borghese’s families. Besides the numerous medieval archeological finds, the district shows traces of the Renaissance period in the windows of many buildings or the door of the Madonna delle Grazie’s Church. Not far from the center of the village, almost astride the Vezza torrent and next to the road and highway connecting Orte to Viterbo, there are the ruins of Colle Casale Castle, a medieval construction whose city walls and penatagonal tower featuring Ghibelline merlons, are still preserved.
