It is a wayside cairn, a drystone cairn being a carefully stacked construction built without mortar, relying entirely on the weight and fit of the stones themselves. This one is modest in scale, roughly 1.8 metres across and just over a metre in height, and it is finished with a flat slab set upright on its top, a detail that gives it an oddly formal quality, something between a marker and a monument.

The tradition attached to it is precise in its grief, if not in its date. According to local account, a woman who lived nearby raised the cairn at the spot where she paused, or perhaps where she stood and watched, as her son's body was carried along the road toward the chapel at Eochaill. The phrase used is simply 'long ago', which in the context of island oral tradition could mean a generation or several. That single upright slab on the summit, set with evident deliberateness, suggests the cairn was not a casual accumulation of stones but a considered act of commemoration, built to last and built to be seen. The information was communicated to researchers by T. Robinson, whose meticulous documentation of Inis Mór's landscape and place-lore has preserved many such details that would otherwise have gone unrecorded.

The cairn stands in Eoghanacht, in the townland system that divides Inis Mór's western reaches, and it remains on the northern side of the road at the village's western end. Given how quietly it sits in a landscape already dense with ancient stonework, it is the kind of thing you need to be looking for.
