Roman Catholic Diocese of Mariana and Accia
The Diocese of Mariana and Acci or Diocese of Accia and Mariana ("Latin: Dioecesis Acciensis et Marianensis") was a Roman Catholic ecclesiastical territory. It is now a titular see. History. The Diocese of Mariana was a Roman Catholic diocese seated in the Ancient Roman city of Mariana, Corsica. Traditionally it was claimed to have existed already in the time of the apostles, but there is no evidence for that; the whole of Corsica was apparently Christianised by 439. The diocese was united with the diocese of Accia (or Acci) in 1563, and known  thereafter as the diocese of Mariana and Accia. The bishop of Mariana and Accia transferred his episcopal seat from Mariana in 1440 to Vescovato Cathedral and again in 1570 to Bastia Cathedral. The bishopric was suppressed in 1801 in favour of the diocese of Ajaccio, along with all other Corsican bishoprics. The title of Bishop of Mariana in Corsica continues in use. Bishops.
