The Diocese of Sicca Veneria was an episcopal see of Africa Proconsularis, and was a suffragan of the bishops of Carthage.[citation needed] The cathedra of the bishopric was in the Roman colonia (highest ranking city) of Colonia Julia Veneria Cirta Nova Iulia.[1][2] The bishopric was founded in early Christianity; it ceased to function sometime after the Muslim conquest of the Maghreb.
It exists today as a titular see of the Roman Catholic Church. The current bishop is Lajos Varga of Hungary.
Remains of the bishopric included ruins at El Kef of a cathedral, baptistry, Christian burials, and numerous Christian inscriptions.[3]
