It declined in the 5th and 6th centuries ce and disappeared from history after the Arab invasion of the 7th century.
The Turks stationed a small military garrison there, and, after French rule began in Algeria in 1830,
Tebessa was developed as the easternmost of the Algerian gateways to the south.
Dominating the town is a walled Byzantine citadel, comprising a square with 12 towers and 4 gateways.
To the north is a Roman quadric frontal arch erected during the reign of the emperor Caracalla (214 ce).
An outstanding Christian basilica stands 1 mile (1.6 km) north of the town centre. There are also ruins of a Roman amphitheatre, thermal baths,
and a temple of Minerva. In addition to working the phosphate mines of el-Kouif (northeast of the town), the town’s present-day inhabitants engage in trade,
especially in sheep, esparto grass, and grain, and also weave carpets.
We look forward to seeing you in Tebessa in PAIS conference.
