The earthwork sits about 300 metres east of the townland boundary with Castleoliver, and to the untrained eye it reads as little more than a slight rise in a field, the kind of thing easily dismissed as a quirk of drainage or an old dumping ground. But its geometry tells a different story.

The feature was recorded on the 1897 edition of the Ordnance Survey Ireland 25-inch map, where it appears as a raised, sub-circular area measuring roughly 37 metres on its northwest-to-southeast axis and 34 metres northeast-to-southwest. It is defined by a scarp, a pronounced edge or drop in the ground surface, running from the southwest, around the north, and back down to the southeast. That kind of deliberately shaped perimeter, enclosing a roughly circular interior space, is a common characteristic of early Irish earthwork enclosures, which could have served any number of purposes over the centuries, from settlement and agriculture to ritual or defensive use. The site was compiled by Martin Fitzpatrick and uploaded to record in November 2021.

For anyone wanting to locate it, the earthwork is most legible not from the ground but from above. It registers as a faint oval-shaped cropmark on Google Earth orthoimages, the kind of shadow in the vegetation that only becomes meaningful once you know what you are looking at. Cropmarks appear when buried or partially buried features affect how plants above them grow or dry out, with the underlying structure betraying itself through subtle differences in colour or height. On the ground, the approach is across upland pasture that has been improved and worked over time, which makes the survival of any surface trace here quietly notable. The scarp itself is the thing to look for, that gentle but purposeful slope that marks where someone, at some point, shaped this particular patch of ground.
