But a closer look reveals a subtly raised circular platform, roughly 21 metres across, its edges defined by a worn scarp that drops somewhere between half a metre and just under a metre and a half. Mature deciduous trees grow in a ring across its surface, and it is partly this detail that makes the place quietly interesting: what began as an early medieval earthwork appears to have ended its working life as a deliberate planting feature in somebody's farmland.

The site belongs to a category of monument known as a rath, the most common type of ringfort in Ireland. Raths were typically enclosed farmsteads of the early medieval period, surrounded by one or more earthen banks and a fosse, the external ditch that accompanied them. Here, however, the fosse has entirely vanished, and no original entrance can be made out. The earthwork does not appear on the 1837 edition of the Ordnance Survey six-inch map, though it is marked as a circular enclosure labelled 'Fort' on the 1883 revised edition. That gap in the cartographic record is not necessarily evidence that the monument postdates 1837; early OS surveyors sometimes omitted earthworks of this kind. What the comparison does suggest is that, by the later nineteenth century, the feature was considered significant enough to record. The trees growing on it point to a later, secondary use: planting a ring of trees on or around a pre-existing circular earthwork was a recognisable practice in Irish farming landscapes, giving a purely practical windbreak or boundary marker a ready-made foundation.
