That modest fate is not unusual for sites of this kind. What is quietly interesting here is the persistence of the thing: the same circular feature, roughly fifteen metres across, was recorded on the Ordnance Survey six-inch map of 1842 and again on the equivalent map of 1904, marked each time with the hachured symbol that cartographers used to indicate an earthen enclosure.

The enclosure itself consists of a low earthen bank encircling the top of the knoll, with a shallow external fosse, the term for a ditch dug around the outside of an earthwork, running around it. The bank is modest by any measure, rising only about ten centimetres above the interior ground level and thirty centimetres above the outer ground, while the fosse is barely ten centimetres deep. A gap of roughly 1.4 metres in the bank to the north-west likely marks the original entrance. Inside, the ground is uneven and slightly elevated, following the natural rise of the knoll, and there is a small depression near the south-western edge of the interior. Enclosures of this general type, circular earthen boundaries enclosing a modest area, appear across Ireland in various forms and periods, and their original functions range from settlement to ritual to agricultural use. Here, no firm date or original purpose has been established, and local tradition offers only the sheep pen explanation, which almost certainly belongs to a much later phase of use rather than the enclosure's origins.
