On the floor of the upper Araglin river valley in County Waterford, six upright stones curve into a semicircle roughly four and a half metres across, open to the north. It is not a complete ring, and that incompleteness is not an accident of time or damage; the arc was always a partial one, a deliberate half-gesture rather than an enclosure. A kerb circle of this kind typically functioned as a low stone border around a burial cairn, defining the edge of a mound of stones or earth, though this particular example sits slightly apart from its nearest neighbours rather than encircling anything obvious on its own ground.

The site lies at the southern edge of a ravine cut by a tributary stream, at the precise point where that stream bends north-west to join the broader valley. That positioning, at a topographic turning point, may or may not be meaningful, but it is the kind of detail that accumulates significance the more you look at this landscape. The monument belongs to a concentrated cluster of prehistoric remains on Coumaraglinmountain, with several others grouped around a cairn circle roughly fifteen metres to the north-west. Michael Moore, writing in the Archaeological Inventory of County Waterford published in 1999, identified and documented the group in detail. The whole complex is protected under the National Monuments (Preservation) Order No. 4 of 1996, which reflects just how unusual and well-preserved this gathering of early monuments is considered to be.
