The site does not appear on Ordnance Survey maps, which is itself a small puzzle, and from the ground it reads as little more than a rubbled platform of stone, earth, and scree. What it actually represents is a cashel, the Irish term for a stone-walled ringfort, a type of enclosed settlement built throughout early medieval Ireland, typically as a farmstead for a single family or small community. The enclosing wall has long since collapsed into the landscape, and a stone bank that once divided the interior has followed suit, but the underlying form still holds.

The most detailed account of the site comes from a survey conducted by O'Kelly in 1942 and 1943, the findings of which were published in 1943. O'Kelly recorded a fort roughly 40 metres in diameter, sitting on an outcropping limestone knoll and positioned directly south of a nearby tumulus, which is a prehistoric burial mound, on the same slope. What he described was already well into decay: a collapsed stone rampart around the perimeter, a ruined internal bank running roughly east-northeast to west-southwest across the centre of the platform, and a curious arrangement of ancient fencing. One line of fencing met the western edge of the platform and another ran northward before turning inward and tracing a concentric path around the monument, eventually disappearing into a later north-south wall on the eastern side. That layering of periods, where early medieval stonework, ancient field boundaries, and more recent agricultural walls intersect, gives the site an almost palimpsestic quality. Aerial photography taken in October 2002 and held by the Archaeological Survey of Ireland confirmed that the outline of the monument remains legible from above, even where it is difficult to read at ground level.

Access to this part of Cromwell Hill involves crossing private agricultural land, so landowner permission should be sought before visiting. The site is unmarked and unmanaged, and there is no interpretive signage. Ground-level visibility is limited, and the collapsed nature of the remains means that patience and a reasonable familiarity with reading earthworks will serve a visitor better than any expectation of obvious structure. The aerial photographs lodged with the Archaeological Survey of Ireland offer a useful frame of reference before going. The nearby tumulus to the north is a related point of interest on the same slope and, taken together, the two monuments suggest this hillside carried some significance across more than one period of Irish prehistory and early history.
