Sutri (Latin Sutrium) is an Ancient town, modern comune and former bishopric (now a Latin titular see) in the province of Viterbo, about 50 kilometres (31 mi) from Rome and about 30 kilometres (19 mi) south of Viterbo. It is picturesquely situated on a narrow tuff hill, surrounded by ravines, a narrow neck on the west alone connecting it with the surrounding country.
