[1] Within the Limes of western Numidia, the site of Medjdel (or Medjedel) reveals a military structure of significant importance that testifies to its major strategic role in the region, is described in the late 1930s.

Square in shape, it had dimensions estimated at between 22 and 25 metres on each side, with projecting bastions arranged in a fan-shape at each corner, a typical feature of Roman defensive works of the Late Period.

[5] Situated near the defile leading into the depression of the zahrez, to the south of the eastern horn of the Zahrez Chergui, the fortress occupied a dominant strategic position, effectively controlling the routes through the region.

The question of the later occupation of Medjdel by Roman forces remains a subject of debate among scholars[7] Artefacts discovered during excavations, such as terracotta sling balls, suggest the probable presence of a garrison inside the fortress.

[8] However, the precise identification of this military unit as well as its exact composition remain question marks requiring in-depth analysis.
