The following identifications have been suggested: Birket Isra`il, near St Stephen's gate; a large cistern, near St Anne's church; the "Twin Pools," north of the Haram (the ancient Temple area); the Hammam esh-Shifa', or pool of healing, west of the Haram; the Virgin's fountain, south of the Haram; and the "Pool of Siloam."
Cirta (Constantine) and Bulla Regia (Hammam Darraj), its chief towns, received coloniae of soldiers and veterans, as well as Theveste (Tebessa) and Thamugas (Timgad).
At the north-east corner of the town is a sulphur spring, and 4 leagues to the south there is a hot sulphur spring (Hammam `Ali), much frequented by invalids.
The springs are known to the Arabs as Hammam Meskutin (the " accursed baths ").
Within a mile of Hammam Meskutin are ferruginous and sulphureous springs.
