Naratcata

Naratcata was the seat of an ancient episcopal see of the Roman province of Numidia. The location of the diocese seat and cathedra is not known but presumably was a place called Naratcatensis and was somewhere in today's Algeria.
There are two known bishops of Naratcata:

Fortunatianus attended the synod meeting in Carthage in 484 by the Vandal king Huneric after which Fortunatianus was later exiled;
Colombo was among the fathers of another Carthaginian council in 525, celebrated under Hilderic.

The diocese ceased to function with the Muslim conquest of the Maghreb but was re-established in name in 1933. Today Naratcata survives as a titular bishopric and the bishop is Jean-Pierre Kwambamba Masi, of Kinshasa, who replaced Fernando Bascopé Müller in 2014.
