It shows itself only from above, as a cropmark, the kind of ghostly outline that appears when a buried ditch causes the soil above it to retain moisture differently from the surrounding ground, producing a faint but legible difference in how the crops grow. Spotted on satellite imagery, it would be easy to drive past without any awareness that something lies beneath the surface of an ordinary working field.

The enclosure is oval in shape, measuring roughly 40 metres on its northeast to southwest axis and around 35 metres northwest to southeast. It is defined by a fosse, essentially a ditch dug as a boundary, which in this case has long since silted up and been absorbed into the agricultural landscape. Features of this kind are broadly associated with early medieval settlement in Ireland, where enclosed spaces served as farmsteads, religious sites, or places of local significance, though without excavation it is impossible to say with certainty what purpose this particular one served. The site was identified and reported by Jean-Charles Caillère, who noticed its outline on Apple Maps satellite imagery, a reminder that archaeological discovery is not always the result of fieldwork with trowels and theodolites.
