Pertusa was an ancient city and diocese in Tunisia.
The Bishopric of Ad Pertusa was centered on the ancient Roman civitas of Pertvsa, which has been identified with ruins at modern El-Haraïria, an outer suburb of Tunis.
During the Roman Empire Pertusa was located in the Roman province of Africa Proconsularis and was important enough to become a bishopric, which was suffragan to the nearby Metropolitan, of Carthage.
The town is mentioned[1] in the Antonini Itinerarium.
[2] It was nominally revived in 1933 as a Latin titular see of the lowest (episcopal) in 1933, and has almost constantly been awarded.
