It belongs to a class of monument known as a ring-ditch, the term used for a roughly circular earthen or rock-cut ditch, often all that remains of a prehistoric burial mound after centuries of ploughing have levelled the upstanding structure above it. What survives is not the ditch itself, at least not visibly, but its impression on the crop growing above it. Where the fill of an ancient cut is richer or more moisture-retentive than the surrounding soil, the plants above it grow fractionally taller or ripen slightly later, producing a faint difference in colour or height that becomes legible as a pattern when seen from altitude.

This particular site came to light not through excavation or fieldwork but through the close reading of aerial photography. A Google Earth image captured on 14 July 2018 showed the cropmark clearly enough to allow the feature to be identified and recorded. The observation was made by Simon Dowling and subsequently compiled by Caimin O'Brien. The ring-ditch measures approximately thirteen metres in diameter, which is consistent with the kind of modest barrow tradition found widely across prehistoric Ireland, though without excavation it is impossible to say more about its date, function, or the people who made it.
