The structure is a ring barrow, a type of prehistoric funerary monument in which a burial mound or platform is encircled by a ditch and an outer bank, the whole arrangement functioning as a bounded, ceremonial space for the dead. What makes this particular example worth pausing over is the precision still legible in its form, even after however many centuries of grass and weather have softened its edges.

The raised central area measures thirty metres in diameter and is defined by an earthen scarp on its outer edge. Beyond that runs a fosse, a ditch roughly 3.6 metres wide, and then a substantial outer bank, which stands 1.2 metres high on its inner face and 0.65 metres on the outside. To the east, there is a deliberate four-metre gap in that outer bank, with a corresponding causeway preserved across the fosse below it. This is the original entrance, oriented towards the rising sun, a detail that connects the monument to a broader tradition of eastward orientation found at prehistoric sites across Ireland and Britain. The careful engineering of the entrance gap, maintained as a causeway rather than simply left as open ground, suggests this threshold carried some formal significance in the monument's original use.
