Ancient Diocese of Orange

The ancient residential diocese of Orange in the Comtat Venaissin in Provence, a fief belonging to the Papacy, was suppressed by the French government during the French Revolution. It was revived in 2009 as a titular see of the Roman Catholic Church.

The city now called Orange in southern France was called Arausio in Roman times. It had been founded as a retirement colony for veterans of the Roman Army who had served under Augustus during his campaigns against Marc Antony. It became the seat of a bishop very probably towards the end of the 3rd century: at the Synod of Arles in 314, its bishop was represented by a priest named Faustinus. The first bishop of Arausio whose name is given in extant documents was Constantius, who took part in the Council of Aquileia, 381. From the early 5th century, the see was a suffragan of the metropolitan see of Arles.
