The site is known entirely from a cropmark, the faint but legible trace left when buried archaeological features cause overlying crops to grow differently, revealing the outlines of ditches or walls that have long since disappeared beneath the soil. In this case, the cropmark outlines the fosse, or defensive ditch, of a roughly oval enclosure measuring approximately twenty-five metres in diameter.

The enclosure came to light in an aerial photograph taken in July 1989 as part of a systematic aerial survey programme. At that scale and from that angle, the ground gives up details invisible to anyone standing in the field. The oval shape and the presence of a surrounding fosse suggest a class of monument that is common across Ireland, typically associated with early medieval settlement, though the site has not been excavated and its precise date and function remain unknown. What is clear is that it does not sit in isolation. It lies within a broader field system, meaning the enclosure was once part of a worked and organised landscape, surrounded by boundaries and divisions that also, for the most part, survive only underground.
