The Italian Catholic Diocese of Aosta (Latin: Dioecesis Augustana) has existed in its modern form since 1817. It is a suffragan of the Archdiocese of Turin.
Although Ursus is sometimes said to have been the first bishop, this is controverted. The first certainly known bishop is St. Eustasius, whose name coupled with Aosta is signed to a letter sent to Pope Leo I by the second Synod of Milan in 451. In the cathedral treasury is a consular diptych of Anicius Petronius Probus, Roman consul in 406, which shows the Emperor Honorius. (It was discovered in 1833.) From the ninth century the list of bishops is fairly complete. Bernard of Menthon (1008), Archdeacon of Aosta, founded the hospice on the Alps named after him, as a relief to pilgrims.
In the 10th and early 11th centuries, the bishops of Aosta ruled the surrounding country as its secular counts. The two titles were separated at or following the death of Bishop Anselm of Aosta, in 1026, owing to Conrad II's desire to strengthen his position near the important Little St Bernard Pass and distrust of Burchard, Anselm's successor and a relative of various nobles opposed to Conrad's claims in Burgundy. (Burchard would subsequently rise in a failed revolt; he was later translated to Lyons.)
His namesake, Anselm, Archbishop of Canterbury (1033-1109), was also a native of Aosta and probably related to its dynasty of bishops; however, rather than remain in local service, he travelled to Bec Abbey in Normandy and ultimately became primate over Norman England instead.
The see was suppressed in 1802 and re-established in 1817.
Territory and parishes
The diocese, which covers an area of 3,262 km² and has a population of 129,288, is divided into 93 parishes. All are in the (civil) region of Aosta Valley. A list of parishes by commune follows; locations (villages or neighbourhoods) within a commune are shown in brackets.
