Nigizubi was a Roman– Berber town in the province of Numidia. It was located in modern Algeria. [1] It was also the seat of an ancient bishopric. [2] [3] during the Vandal Kingdom and Roman Empire. [4] The exact location of the ancient town is now lost but it was somewhere in north-eastern Algeria.
The only known bishop of this diocese was the Donatist bishop, Gaudenzio, who took part in the Council of Carthage (411), [5] between Catholic and Donatist bishops in Numidia.
The diocese ceased to effectively function following the Muslim conquest of the Maghreb in the 7th century. Today Nigizubi Diocese survives as a titular bishopric [6] [7] and the current bishop is Adolfo Eduardo José Bittschi Mayer, of Sucre.
