Tébessa
Tébessa stands in the highlands of eastern Algeria near the Tunisian frontier. Known to the Romans as Theveste, it was a colony and a station of the Third Augustan Legion. Its ancient monuments include a temple, a Christian basilica and the Arch of Caracalla, built in the early third century. Byzantine builders later incorporated the arch into the town’s walls. Medieval Arab geographers still mentioned Tébessa, though it had become a smaller center.
