The site is a ring-ditch, a type of monument that survives not as standing stone or earthwork but as a cropmark: a faint circular ghost impressed on a growing cereal crop, visible from above when buried features cause the soil to retain moisture or drain differently from the surrounding ground. The circle in question measures roughly eleven metres in external diameter, defined by a ditch approximately one metre wide. There is no gap or break in the ditch to indicate an original entrance.

Ring-ditches of this kind are generally understood to be the remains of prehistoric funerary or ceremonial enclosures, often the eroded traces of a round barrow where the central mound has long since been ploughed away. What remains is essentially the circular trench that once surrounded a burial, now detectable only through the behaviour of crops above it. This particular example sits close to the southern boundary of its field, roughly 345 metres north-west of a recorded enclosure and about 1.2 kilometres south-west of the Irish Sea coastline at Holmpatrick. It is not alone: a second ring-ditch lies approximately 140 metres to the north-east in the same field, suggesting the area may have held some significance over a long period. The site was compiled by Tom Condit and uploaded to the national record in April 2021, with the cropmark itself identified on Apple Maps aerial imagery captured in June 2018.

Because the monument is entirely subsurface, there is nothing physically visible at ground level. The field is under arable cultivation, and access is not something a casual visitor could simply arrange. The cropmark is best appreciated through aerial or satellite imagery, and the June 2018 Apple Maps capture remains a useful reference point. Cropmarks of this kind tend to appear most clearly during dry summers, when moisture stress reveals the buried ditches as slightly greener or more vigorous lines of growth against the parched surrounding crop. Anyone with an interest in aerial archaeology and access to online mapping tools will find it a useful case study in how much of Ireland's prehistoric landscape persists invisibly, readable only from above.
