Lambaesis (Lambæsis), Lambaisis or Lambaesa (Lambèse in colonial French), is a Roman archaeological site in Algeria, 11 km (7 mi) southeast of Batna and 27 km (17 mi) west of Timgad, located next to the modern village of Tazoult.

[citation needed] The town is built 622 m above sea level in the plain and on the spurs of the Djebel Asker[2]By AD 166 mention is made of the decurions of a vicus, 10 curiae of which are known by name; and the vicus became a municipium probably at the time when it was made the capital of the newly founded province of Numidia.

Indeed, under Septimius Severus (AD 193 ), Numidia was separated from Africa Vetus, and governed by an imperial procurator.

The province remained under Vandal rule, but was effectively limited to the coastal areas by Berber raids.

The ruins are situated on the lower terraces of the Aures Mountains, and consist of triumphal arches (one to Septimius Severus, another to Commodus), temples, aqueducts, vestiges of an amphitheatre, baths and an immense quantity of masonry belonging to private houses.

The capitol or temple dedicated to Jupiter, Juno and Minerva, which has been cleared of debris, has a portico with eight columns.

On level ground about two-thirds of a mile from the centre of the ancient town stands the camp, its site now partly occupied by the penitentiary and its gardens.

The ruins of both city and camp have yielded many inscriptions (Renier edited 1500, and there are 4185 in CIL viii); and, though a very large proportion are epitaphs of the barest kind, the more important pieces supply an outline of the history of the place.

About 2 miles (3.2 km) south of Lambessa are the ruins of Markuna, the ancient Verecunda, including two triumphal arches.
