Bishoprics
From MedNub
Adams 2010, 51 (Qasr Ibrim: The Earlier Medieval Period) notes, "One ecclesiastical history speaks of seven bishoprics in the united kingdom of Makouria and Nobadia... but only five cathedrals have been identified archaeologically. They are Philae, Qasr Ibrim, Gebel Adda, Faras, and Old Dongola." To this list we should add Sai.
