The diocese of Civita Castellana is a Roman Catholic ecclesiastical territory in Latium, central Italy. It has existed in the current form since 1986, when the diocese of Nepi e Sutri was united into the diocese of Civita Castellana, Orte e Gallese, dating from 1805 (the name change was made in 1991). It is a suffragan of the Roman Catholic Archdiocese of Rome.[1]
The first known bishop of Civita Castellana is Crescentius. He discovered, in 998, the relics of Martianus and Johannes. In 1252 the diocese of Gallese was incorporated with that of Civita Castellana. Reestablished in 1562, Gallese was again suppressed in 1573.
In 1437 the diocese was united with the diocese of Orte. Orte (Orta, the ancient Horta) is some distance north of Rome.
Thirty-eight bishops of Civita Castellana are known previous to its union with Orte. Subsequent bishops include:
