The rath at Cloonagleavragh measures roughly 22 metres across, enclosed by an earthen bank about 5.5 metres wide and only half a metre high on the interior, with no visible fosse, the external ditch that typically accompanies such structures, remaining at ground level. What does survive is a clear break of about 3.75 metres in the northeastern arc of the bank, which marks the position of the original entrance used by whoever called this enclosure home, likely during the early medieval period when raths served as defended farmsteads across Ireland.

What makes this particular site quietly puzzling is the gap between the recorded map and the physical ground. A souterrain, an underground stone-lined passage used for storage or refuge and common features within ringforts, was marked inside the enclosure on the Record of Monuments and Places as recently as 1995. When the site was examined more recently, no trace of it could be found. Whether it collapsed, was filled in, or was simply a cartographic error is unclear. The ringfort itself occupies a narrow ridge oriented roughly north-northwest to east-southeast, a subtle topographical choice that speaks to the deliberate, if understated, site selection typical of early medieval settlement. The bank, though reduced by time and agriculture, still traces a recognisable circle across the pasture.
