Simingi was a Roman era civitas (town) of the Roman province of Africa Proconsularis.
The town was the seat of an ancient bishopric, suffragan of the Archdiocese of Carthage.[1] [2] Only two bishops of this diocese are documented.
In modern times Simingi became a titular bishopric. Simingi's bishop is Josef Holtkotte of Paderborn, Germany.
