The southern and western stretches of its bank have been absorbed into the modern field fence system, so a farmer walking the perimeter today is, without necessarily thinking about it, following a line that was laid out well over a thousand years ago.

The earthwork is a rath, the Irish term for a ringfort, the most common type of archaeological monument in the country. These were the enclosed farmsteads of early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries, where a family would have lived, kept livestock, and organised their small agricultural world within a defined boundary. This example is modest but legible: a roughly circular enclosure measuring thirty-five metres across in both directions, defined by an earthen bank that stands about a metre and a half on its outer face, though only around twenty centimetres above the interior ground level. That interior has been deliberately levelled up on the northern side, a practical response to the natural slope of the hillside that gives the enclosed space a reasonably flat surface. The bank itself is stone-faced in places, with loose stones scattered at the base of its outer face, and a gap seven metres wide in the bank to the north-north-west likely marks the original entrance.
