Althiburos

Althiburos was an ancient Berber, Carthaginian, and Roman settlement in what is now the Dahmani Delegation of the Kef Governorate of Tunisia. During the reign of emperor Hadrian, it became a municipality with Italian rights. It was the seat of a Christian bishop from the 4th to 7th centuries. The settlement was destroyed during the Muslim invasions and the area's population center moved to Ebba Ksour on the plain. This left Althiburos's ruins largely intact; they were rediscovered by travelers in the 18th century.
