The Diocese of Digne (Latin: Dioecesis Diniensis; French: Diocèse de Digne) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in France. Erected in the 4th century as the Diocese of Digne, the diocese has been known as the Diocese of Digne–Riez–Sisteron since 1922. The diocese comprises the entire department of Alpes-de-Haute-Provence, in the Region of Provence-Alpes-Côte d'Azur. The diocese was a suffragan diocese of the Archdiocese of Aix-en-Provence and Arles until 2002 and is now a suffragan diocese in the ecclesiastical province of the metropolitan Archdiocese of Marseille. The Bishop of Digne's cathedra is found in Digne Cathedral at the episcopal see of Digne-les-Bains. Extent By the Concordat of 1801, this diocese was made to include the two departments of the Hautes-Alpes and the Basses-Alpes; and in addition it received the former Diocese of Digne, the Archdiocese of Embrun, the dioceses of Gap, Sisteron and Senez, a part of the dioceses of Glandèves and Riez, and fourteen parishes in the Archdiocese of Aix-en-Provence and Arles and the Diocese of Apt. In 1822 Gap was revived as an episcopal see, with its territory comprising the department of the Hautes-Alpes. The present Diocese of Digne, divested of the department of the Hautes Alpes, covers the territory formerly included in the Dioceses of Digne, Senez, Glandèves, Riez and Sisteron. History The former diocese of Digne was evangelized by Saints Domninus and Vincentius who came from North Africa in the second half of the fourth century with Saint Marcellinus, the Apostle of Embrun. There is no evidence, however, that they were bishops. The first historically known bishop was Pentadius who attended the Council of Agde in 506. Cathedral The original cathedral of Digne (Cathédrale Notre-Dame-du-Bourg de Digne) was in Bourg, the city of Digne and the Bourg being two separate legal entities. The earliest architectural remains on the site where the cathedral now stands consist of a wall of Gallo-Roman construction, which local authorities and amateurs would like to push back to the time of Constantine, or at least, as Canon J.-F. Cruvellier admits, to the Constantinian era. It would be completely improper, however, to call this church a cathedral, since it cannot be shown that there was a bishop in Digne until after 500. The second church, as was first asserted by Honoré Bouche, was traditionally believed to have been built or rebuilt by Charlemagne. He made the same
