Look more carefully and its geometry becomes apparent: a gently concave top, a slightly raised rim running around the edge, and sides that slope away in a consistent, deliberate curve. This is an embanked barrow, a form of prehistoric funerary monument, and its saucer-shaped profile is precisely what distinguishes it from a natural rise or a collapsed field feature. The mound measures roughly thirteen to fourteen metres across and rises to about 1.6 metres at its north-eastern end, making it modest in scale but clear enough in form once the eye is trained.

The mound sits at a break of slope on a north-west to south-east ridge, a position that would have commanded wide views across the lake to the south-west, though higher ground closes the prospect between south-west and north. Whether that outlook mattered to whoever built it is unknown, but prehistoric monuments are frequently sited with deliberate attention to the landscape around them. By 1838, when the first Ordnance Survey six-inch mapping of the area was carried out, the feature was recorded as a circular embanked enclosure with a diameter of between fifteen and twenty metres. By the 1917 edition of the same map series, it appeared as a smaller hachured circle, suggesting some shrinkage or erosion in the intervening decades, though the monument has since remained in reasonably good condition. It is predominantly earthen in construction, with occasional stones protruding from the sloping sides, and is covered in grass, with a few hawthorn bushes growing around the perimeter. A field wall runs immediately to its south-west.

The barrow sits within improved pasture, so the surrounding land has been worked and altered over generations, which makes the survival of the mound itself quietly notable. Hawthorn growing on the edges of old monuments is a common enough sight in Ireland, the trees often left deliberately by farmers who were cautious about disturbing such places.
