The site is located near Jougan, Tunisia[1][2] 20 kilometers south west of Zaghouan.
[3] The ruins are considered to be two separate Roman settlements, situated on opposites sides of a wadi: Henchir Ksour Dzemda is a set of ruins located at Dzemda in Tunisia,[4][5] 20 kilometers south-west of Zaghouan noted for ruins from the Roman era,[6] including a structure of Vaulted construction.
Given its location, it is probable that the village was actually an imperial estate, which were common in the area during this time.
During Roman times, Annaeus was near the Municipum of Semta (Africa) which lay on the opposite side of the Faida-Dzemda stream.
The two sets of ruins have been treated in modern times together[14] though the presence of two different bishops in the two settlements indicates separate entities during the Roman and Byzantine era.
