Garriana was a Roman town of the province of Byzacena during late antiquity.
[1] The town has tentatively been identified with the ruins at Henchir-El-Garra in modern Tunisia.
[2][3] The name Henchir-El-Garra simply means the Ruins of Garria.
Ancient Henchir-El-Garra was also the ecclesiastical seat of a Roman Catholic Church episcopal see.
Today Garriana survives as a titular bishopric and Edmar José da Silva of Brazil is the current bishop.
