Diocesi di Viterbo
The Diocese of Viterbo comprises 35 municipalities in Tuscia Viterbese, including Bagnoregio, Bolsena, Castiglione in Teverina, Celleno, Graffignano, and Vitorchiano. It is divided into 99 parishes with more than 300 churches. The seat of the diocese is in medieval Viterbo, in the Palazzo Papale, a 12th-century building famous for being the place where the cardinals, in 1268, elected the Pope in the first and longest modern conclave. The monumental complex, the religious and artistic heart of the city, also includes the Romanesque Cathedral of San Lorenzo and the modern Colle del Duomo Museum in a striking setting enclosed by the famous Loggia delle Benedizioni.
