No earthwork rises from the ground, no crop-mark betrays its outline to the casual walker. It exists, for now, as a pattern in the soil, coaxed into visibility only by geophysical survey.

The feature was identified in 2004 through that kind of survey, which detects buried archaeology by measuring subtle variations in the ground's physical properties rather than by digging. What the instruments recorded was a positive annular feature, meaning the ditch fill reads as denser or wetter than the surrounding soil, tracing a near-complete ring. The circuit is clearest on its northern arc, where the ditch reaches about one and a half metres wide, but the western, southern, and eastern stretches show gaps, most likely the result of centuries of ploughing gradually breaking up the upper fill. At the centre of the enclosed area, the survey also picked up what appears to be a pit. Ring-ditches of this kind are generally understood to be funerary in origin, the eroded remains of a burial mound whose earthen body has long since been levelled, leaving only the encircling ditch as a faint signature. The proximity to the neighbouring ringfort, a type of enclosed farmstead typical of early medieval Ireland, raises questions about the relationship between the two features, though whether one predates the other, or whether the ringfort was deliberately sited beside an already-ancient monument, remains an open question.
