It exists, so far as anyone knows, only as a ghost in the soil, readable solely from the air. Cropmarks of this kind appear when buried features such as ditches or banks influence how overlying crops grow, with deeper disturbed soil above a filled ditch typically retaining more moisture and producing taller, greener growth. Viewed from above, especially in dry summers when the contrast is sharpest, those differences in the crop canopy resolve into shapes that can correspond to ancient enclosures, trackways, or field boundaries.

Aerial photographs taken between 2012 and 2018 reveal an enclosure roughly 77 metres from north to south and 140 metres from east to west, a considerable size, sitting within what is now a tillage field. Alongside the main oval outline, curvilinear marks elsewhere in the field suggest the remnants of a wider field system, implying that whatever activity once took place here extended well beyond a single enclosure. The proportions and oval form are consistent with the kind of large enclosures known from other parts of Ireland, which range from early medieval ringforts to much earlier prehistoric settlements, though without excavation or further survey it would be premature to assign this one to any particular period or purpose.
