Roman Catholic Diocese of Susa

The Roman Catholic Diocese of Susa , in Piedmont , was established in 1772. It is a suffragan of the archdiocese of Turin. The diocese and the city of Susa lie on the main route that leads to Italy from the Mont Cenis Pass and the Col de Montgenèvre.

In early medieval days, Susa seems to have belonged to the Diocese of Maurienne, and was not separated from it until after the conquest of Italy by Charlemagne in 784. The Abbey of St. Justus having been erected in 1029, the abbot had quasi-episcopal jurisdiction. The Benedictines were succeeded by the Canons Regular, and under Pope Benedict XIV the Canons Regular were replaced by secular canons. He ordered that they form a Collegiate Chapter, consisting of four dignities and fourteen Canons.
