The earthwork, roughly 46 metres across in both directions, is enclosed by a rise that barely clears half a metre above the surrounding ground on its outer face. These dimensions place it squarely within the tradition of the rath, the commonest monument type in the Irish landscape: a circular enclosure defined by an earthen bank and, originally, an outer ditch or fosse, most likely built and occupied during the early medieval period, roughly between the fifth and twelfth centuries, and typically serving as a defended farmstead for a family of some local standing.

What makes this particular example quietly interesting is not what can be seen on the ground but what aerial photography reveals. A shadow site, that is, a feature detected through subtle changes in ground level that only become visible when light falls at a low angle across the surface, shows the faint circular trace of the enclosure from above. More intriguingly, a possible cropmark of a fosse, the original ditch that would have run outside the bank, is visible to the north-west. Cropmarks form when buried features affect soil moisture and in turn the growth of grass or grain above them, making ancient ditches and foundations legible from the air even when they have long since silted up and been smoothed over at ground level. A possible entrance opens to the east, and the interior ground slopes gently southward. Together, these details sketch the outline of a place that has been quiet farmland for a very long time, with its earlier life only glimpsed in passing light and dry summers.
