Roughly subrectangular in shape, measuring about 58 metres east to west and 30 metres north to south, it is defined along its eastern and southern sides by an earthen bank, with a natural scarp forming the northern boundary and a field bank closing off the west. None of these elements are dramatic; none of them shout their purpose. The site is poorly preserved, and what survives is just enough to register as deliberate without revealing quite what was intended.

What makes the enclosure quietly puzzling is its relationship to the landscape around it. Eighty metres to the northwest lies a ringfort, a type of enclosed circular or oval settlement typical of early medieval Ireland, usually dating from roughly the fifth to the twelfth centuries and associated with farming families of some local standing. The enclosure on the hillock is close enough to suggest a connection, yet different enough in form and positioning to complicate any neat interpretation. Archaeologists have raised the possibility that it may be a landscape feature rather than a settlement or enclosure in any functional sense, which is a careful way of acknowledging that its original role is genuinely unclear. It could have served as a boundary marker, an animal pen, or something associated with the nearby ringfort. It could also be the result of field division at a much later period, its earthworks gradually losing definition over centuries of agricultural use.
