On the floor of a mountain valley in the Waterford uplands, where a tributary stream bends sharply north-westward before dropping into a ravine, a small mound of heather-covered stones sits quietly in the landscape. It measures just 1.5 metres north to south and 1.3 metres east to west, defined by four kerbstones, the low border-stones that mark the outer edge of a cairn and give it its shape. Small as it is, it is not alone. This cairn is part of a concentrated cluster of prehistoric monuments on Coumaraglinmountain, gathered within a short distance of one another in the upper Araglin river valley.

The cairn sits just east of a cairn circle, a related monument type in which a ring of stones, sometimes kerbed, sometimes more loosely arranged, defines a circular space that typically served a funerary or ceremonial purpose during the Bronze Age. The grouping of such monuments together is a pattern recognised elsewhere in Irish uplands, where elevated ground and valley edges were favoured for the placement of the dead or for ritual activity. Michael Moore documented this cluster in his 1995 survey work, later published as part of the Archaeological Inventory of County Waterford. The site carries a preservation order dating from 1996, which places it under the protection of the National Monuments Acts.
