Roman remains are now the main attraction of the city. We find:

– The Solomon said wall that encircles the center of the old city; it dates from the 6th century. These ramparts are flanked by thirteen square towers and open to the outside through four doors.

– One of the four doors is a triumphal arch (Gate of Caracalla)

dating from 214 AD

This building, which was used at the northern entrance of the city, is located in a square at the junction of two paths. The four facades of this gate are identical.

– The temple dedicated to Minerva from the early 3rd century. The interior walls of the temple are adorned with beautiful mosaics. We find in various prehistoric tools (coins, weapons, lamps, etc.)

– The entire basilica (ruins of the Basilica of St. Crispina) located outside the speakers of the old city north of the Arch of Caracalla, is surrounded by chapels, baptisteries, catacombs and gardens. It contains paths, stables, huge staircases, underground paths and many Roman buildings.

– This basilica building dedicated to a local saint, St Crispina, and dating from the late 4th century, is one of the largest in Africa.

– Not far from the central market of the town, are the ruins of an amphitheater dating from the 4th century.

– The aqueduct which supplied the city.

– The Roman bridge.
