It leaves no trace at the surface, no earthwork, no raised bank, no obvious irregularity in the soil. The only evidence of its existence came from the air.

In 1996, an aerial photograph revealed the enclosure as a cropmark, the kind of faint but telling signature that forms when buried features affect how crops grow above them. Soil compressed or disturbed by ancient walls or ditches retains moisture differently from undisturbed ground, and in a dry season especially, the difference shows up in the colour and height of the crop above. The photograph captured an oval-shaped enclosure sitting on a slight rise, a position that would have offered clear views in every direction, something that likely mattered to whoever first marked out this space. A possible field system appears to be associated with it, suggesting the enclosure was not an isolated feature but part of a broader pattern of land use. Without excavation, the date and function of the enclosure remain uncertain, though oval enclosures of this kind in Ireland are often associated with early medieval settlement or agricultural activity.
