The surface dips, rises, and describes a near-perfect circle just four metres across, its geometry too deliberate to belong to any geological accident. What lies here is a ring barrow, a class of prehistoric funerary monument in which a low central mound is enclosed by a surrounding ditch, known as a fosse, sometimes accompanied by an outer earthen bank. They are found across Ireland, generally associated with Bronze Age burial practice, yet they tend to go unnoticed in ordinary farmland, their profiles worn down over millennia of grazing and cultivation.

This particular example is small but structurally legible. The fosse measures roughly 2.45 metres wide and survives to a depth of around 0.18 metres, encircling a domed interior that slopes gently down on all sides toward the ditch. The geometry is slightly counterintuitive: the perimeter of the interior sits about 0.08 metres below the level of the surrounding ground, while the crown at the very centre of the dome rises back up to meet that same exterior ground level, giving the whole thing the subtle, flattened profile of a lens. Traces of a possible outer bank are also present, best preserved along the northwest to north-northeast arc and across the east to west-southwest, with an internal height of around 0.18 metres and an external height of just 0.05 metres. The monument is visible on aerial photography as a roughly circular enclosure, which is often how such low-lying earthworks are first identified, their shapes rendered legible by shadow, crop variation, or the particular angle of a winter sun.
