Yet the site is a multi-vallate enclosure, meaning it was ringed not by a single bank and ditch but by layered defences, each one compounding whatever sense of boundary or protection the whole thing was meant to convey.

The enclosure occupies a roughly sub-circular area, approximately 25 metres north to south and 29 metres east to west. What survives is a sequence of earthen features: an inner scarp, two fosses (that is, ditches, typically cut to slow or deter approach), and both an intervening and an outer bank. The outer bank stands about 1.2 metres on its inner face, the intervening bank reaches similar heights, and the ditches between them are cut to depths of between half a metre and a full metre. The south-west side carries a substantial breach some 11 metres wide, and there are two further breaks into the interior at the north-north-east, each around 3.5 to 4.5 metres across. These latter openings, along with a sizeable depression to the west of the interior, are thought to suggest quarrying activity at some point in the site's history, probably long after any original function had ceased. A field boundary cuts across parts of the earthwork from north-east to south-west, further interrupting what would once have been a more continuous circuit. A second enclosure of the same broad type sits around 150 metres to the west-north-west, which raises the possibility that this part of Tipperary once held a small cluster of such features, their relationship to one another now largely a matter of conjecture.
