Orvieto [orˈvjɛːto] is a city and comune in the Province of Terni, southwestern Umbria, Italy situated on the flat summit of a large butte of volcanic tuff. The city rises dramatically above the almost-vertical faces of tuff cliffs that are completed by defensive walls built of the same stone called Tufa.
