Walk across the ground above it and you would notice nothing at all. The only reason anyone knows it exists is because, on a single aerial photograph taken on 3 August 1997, the buried remains cast their outline in the crop growing above them, a phenomenon known as a cropmark, where differences in soil depth or moisture cause plants to grow differently over buried features, revealing their shapes from the air in ways invisible at ground level.

The photograph, taken as part of an aerial survey, shows what appears to be a roughly circular feature, most likely the trace of a fosse, which is a defensive or boundary ditch dug around an enclosure. What makes this particular site a little more complex is the presence of a second, concentric fosse running from the north around the east to the south, suggesting the enclosure was once ringed by more than one ditch. That outer fosse also appears to extend westward, though what this implies about the original layout or function of the site remains unclear. A second cropmark enclosure was identified approximately 70 metres to the east, raising the possibility that the two sites were related in some way, though no further detail is available to say how or when. Such enclosed sites in the Irish landscape are often associated with early medieval settlement, but without excavation, the date and purpose of this particular feature remain open questions.
