That is how ring-barrows, a type of burial mound typically dating to the Bronze Age, often survive: too flattened to draw the eye at ground level, yet legible from above as a pattern of soil and shadow.

The site sits on fairly level ground at Cullahill, tilting just slightly southward toward the bog that borders it on that side. Although the mound itself has been levelled over time, a raised circular area roughly 4.3 metres across remains visible, enclosed by a fosse, which is a shallow surrounding ditch, about 2.3 metres wide and still measurable at just under 30 centimetres deep. Beyond the fosse lies a flattened external bank, with some stone still present within it, giving the whole monument an overall diameter of around ten metres. On the eastern side there appears to be a causewayed entrance, a gap in the ditch roughly 2.6 metres wide, which would have provided a formal point of access to the interior, a feature found at a number of ring-barrows elsewhere in Ireland. The site does not appear on either the first-edition Ordnance Survey six-inch map of 1840 or its 1904 revision, suggesting that by those dates it had already been sufficiently reduced to escape notice at ground level.
