It sits on a slight rise in what is now reclaimed pasture, roughly 800 metres south-east of the summit of Derk Hill, and its existence is confirmed not by any marker on the ground but by the faint ghost of a circular outline visible only in aerial photographs and satellite imagery.

A ring barrow is a burial monument of prehistoric date, typically consisting of a low central mound or platform enclosed by a surrounding ditch, known as a fosse, and an outer earthen bank. This particular example is modest in its dimensions, measuring just 3.4 metres north to south and 4.2 metres east to west across the central area, with a fosse roughly 3.6 metres wide and only about 20 to 25 centimetres deep. When the Archaeological Survey of Ireland recorded it in 2007, the bank was best preserved on the north-east to south-east arc, while a linear drainage ditch associated with the nearby Derk House estate had already cut across the north-west corner, truncating the monument. That estate lies around 650 metres to the north-east, and the field system of drainage ditches it generated has shaped the landscape in ways that both obscure and, ironically, help define what survives. What makes the site still more quietly remarkable is that it belongs to a cluster of fourteen barrows concentrated in the southern half of Derk townland, with the nearest companion monument sitting just 15 metres to the west.

The barrow is not signposted and does not appear on standard Ordnance Survey Ireland maps, so anyone hoping to locate it on the ground is essentially working from coordinates and aerial reference points. The clearest views of the monument come from orthophotographs taken between 2005 and 2012, and from a Google Earth image dated 18 November 2018, in which the cropmark of the fosse resolves into a recognisable circle against the surrounding pasture. Cropmarks of this kind tend to show most sharply in dry summers, when differential soil moisture above buried features affects how grass and crops grow. On the ground, the earthworks are low and easily missed, particularly where the drainage ditch has disturbed the north-western edge, so patience and a careful eye for subtle changes in ground level are more useful here than any map.
