We know that in 168AD the city is still a civitas (town) but under Septimius Severus and Caracalla it had been raised to a municipium status.
Babelon records an aqueduct with a source in the South-Vedic area near Ain Sense, a temple and a bridge,[4] later converted into a fortress.[5] 6 kilometres north of the ruins of Bir-el-Ach, was found a Base for statue of Valentinian I (364–375) now on display at the Bardo Museum.[6]
The town was also the seat of an ancient Christian bishopric,[7] [8] and one bishop is known to have attended the Council of Carthage (411). The diocese effectively ceased to function with the Muslim conquest of the Maghreb but was re-established in 1927 as a titular bishopric of the Roman Catholic Church.[9] The current bishop is John Baptist Tseng Chien-tsi.[10] [11]
