It is not immediately dramatic, which is perhaps why it passed largely unrecorded for so long. A cairn, in the Irish archaeological sense, is a mound of stones or earth covering a prehistoric burial, sometimes dating back thousands of years. This one measures roughly ten metres across and rises between one and one and a half metres at its highest point, with a flattened summit spanning about four metres in each direction where loose stones remain exposed at the surface.

The mound's formal recognition came relatively recently. It was added to the Record of Monuments and Places in 1996, drawing on a map annotation made two years earlier by Tom Coffey, who noted it simply as a "small burial mound". That annotation was enough to bring it into the official record, though the site itself had presumably stood in this field for considerably longer, flanked by hazel thickets and open to wide views across the surrounding countryside. The southwestern and western edges show some signs of damage, the kind of gradual erosion that comes from centuries of agricultural use rather than deliberate intervention.
