Zarna was a Roman town of the Roman Empire during late antiquity. An exact location for the town has been lost to history,[1] although that it was in the Roman province of Africa Proconsolare means it must have been in northern Tunisia. In antiquity the town was also the seat of a Christian bishopric,[2] [3] suffragan of the Archdiocese of Carthage. Only one bishop of this diocese is documented Vitale, who took part in the antimonotelita Council of Carthage of 646.
Today Zarna survives as a titular bishopric[4] of the Roman Catholic Church and the current bishop is Francisco Antonio Ceballos Escobar of Puerto Carreño.[5] who replaced Edmar Peron in 2016.[6]
