It is a modest designation for what is, in fact, a boundary cairn, a deliberate accumulation of loose stones placed to mark the edge of a townland, the ancient Irish land division that still defines local identity across the country. This particular cairn sits on a rocky outcrop along a north-south ridge, precisely on the unbuilt boundary line that separates Aghavoghil to the west from Conwal South to the east.

The cairn itself is not large. Roughly two metres in diameter and half a metre high, it is the kind of feature that reads as geological accident until you know what you are looking at. What lends it some additional interest is its relationship to another cairn of the same type located approximately fifty metres to the south. Together, they seem to have served as a pair of waymarkers along the ridge, fixing an administrative and perhaps social boundary onto the physical landscape. That the 1910 map records this one at all suggests it was still recognisable as a feature at the time of the survey, even if its original purpose had long since faded from everyday use. Before fencing and formal surveying, cairns like this were practical tools, understood by anyone who worked or travelled the land and needed to know where one townland ended and another began.
