High on a south-facing slope in Coumtay Glen, in the Comeragh Mountains of County Waterford, there sits a small oval enclosure that resists easy explanation. Roughly seven metres east to west and four metres north to south, it was built from limestone rubble laid in rough courses using drystone technique, the method of stacking stone without mortar that has been used across the Irish uplands for centuries. What makes it slightly unusual is the north wall, which is not a freestanding construction at all but a revetment, meaning it was cut into and backed against the natural hillside slope, letting the mountain itself do part of the structural work.

The character of the walling points to an eighteenth or nineteenth-century date, a period when upland areas like the Comeraghs saw considerable seasonal activity, from grazing and transhumance to small-scale cultivation and the management of mountain pasture. Structures of this kind could have served any number of purposes, from sheltering livestock to providing a temporary refuge for those working the higher ground. A mountain stream runs approximately fifty metres to the west, draining down toward the River Tay, which would have made the immediate area practical for both people and animals. The site was identified and reported by Helen Lawless, whose fieldwork brought this otherwise unrecorded structure to wider attention.
