The fortification was built on a promontory, which advanced into the Danube (whose course is now more than 4.5 km to the northwest), as a narrow split, delimiting today to the northwest lake Hisarlyk. The site can be located 4.5 km south of Gârliciu village, with access via DJ 222F, which intersects with DN 22 A.
Early Roman fortification, in which the cohort I Lusitanorum Cyrenaica (ISM V 118) was probably encamped. The fortification was restored to a smaller scale, probably in 369, according to an inscription discovered at Gârliciu (ILS 770 = IGLR 233). The late fortification certainly was in use in the second half of the 4th century AD, probably by cuneus equitum stablesianorum. We do not have data for the following centuries, but some numismatic finds in the area suggest continued habitation in the 5th – 6th centuries, until the fall of the limes.
In the absence of systematic archaeological research of the site, two stone enclosures of unequal size could be identified on the terrain: the first measures approx. 120 x 120 m, and the smallest (inside the large one), from the late Roman period, measures approx. 85 x 60 m. Both fortifications are protected by a trench and rampart defence system. An ancient tumular necropolis (not researched), probably from the Roman era, was identified in the perimeter of the present-day Gârliciu village.
Based on data collected with the drone and field observations, by integrating them with P. Polonic’s plans, the plan of the fortifications was partially recreated, by reconstructing the enclosures and some buildings following the ditches from the removal of the walls.
The connection between the early fortification at Cius and the two toponyms attested epigraphically in the area, vicus Rami [ – – -] (ISM V 115) and vicus Vergobrittiani (ISM V 117), and the eventual early fortification, however, is unclear.
