At a mountain gap in the Monavullagh Mountains of County Waterford, a solitary standing stone rises 2.3 metres from the ground, its rectangular profile oriented east to west, its flat ridge sloping gently downward toward the west. That alignment may or may not be deliberate, but what makes this stone genuinely curious is a detail that requires close inspection: along one edge, researchers have noted a possible ogham inscription on either side. Ogham is an early medieval script, typically carved as a series of notches and strokes running along a stone's edge, and its presence here, if confirmed, would add a layer of meaning to a monument that already sits within a surprisingly dense cluster of prehistoric remains.

The gap where the stone stands is called Bearna na Madra, a name that translates roughly from the Irish as the gap of the dog or hound. It sits in a natural hollow, with a shoulder of the Monavullaghs rising around 170 metres higher to the north and another around 100 metres higher to the south. This is not an isolated curiosity. Just 17 metres to the north lies a possible cist, a type of small stone-lined burial box often associated with Bronze Age interment, and roughly 10 metres to the south sits an enclosure of uncertain purpose. Michael Moore, writing in 1995 in the Proceedings of the Prehistoric Society, interpreted the broader area as a Bronze Age settlement and ritual centre, which places the standing stone within a landscape that was clearly being shaped, marked, and perhaps venerated over a very long period. The combination of a potentially inscribed standing stone, a probable burial feature, and an enclosure within so compact an area is unusual anywhere in Ireland, and quietly so here in the uplands of Waterford.
