Roman Catholic Diocese of Terni-Narni-Amelia

The diocese of Terni-Narni-Amelia is a Roman Catholic ecclesiastical territory in Umbria, central Italy. It was created in 1983, when the Diocese of Amelia was united to the Diocese of Terni and Narni. The latter had been in turn created in 1907, when the Diocese of Narni was united to the historical Diocese of Terni. The diocese is exempt, i.e. immediately subject to the Holy See, not part of any ecclesiastic province.

Terni is the ancient Interamna Nahars of the Umbrians, and the cathedral, and other churches, are built on the sites of pagan temples. After the Lombard invasion, Terni belonged to the Duchy of Spoleto, and with the latter, came into the Pontifical States. It was at Terni that Pope Zacharias entered into the agreement with King Luitprand for the restitution of the cities of Bieda, Orte, Bomarzo, and Amelia to the Duchy of Rome.
