Sitting on the boundary junction of Baunteen, Ballygeana, and Carrigeen Mountain on Carrignabinnia Mountain in County Limerick, this modest heap of stones served a purpose that was entirely practical rather than ceremonial: it marked a line in the landscape, a physical assertion of where one community's land ended and another's began. Boundary cairns of this kind were commonplace features of the Irish countryside, piled-up accumulations of stone used to define townland limits long before fencing or legal mapping made such things routine. What makes this particular example quietly interesting is how thoroughly it has since vanished, and how inconsistently it was recorded even when it still existed.

The first edition Ordnance Survey six-inch map, published in 1840, makes no mention of the cairn at all, despite the fact that two companion boundary cairns sit within 75 metres of it to the south-west and south-east respectively. By the time of the 1897 twenty-five-inch edition, it had been annotated simply as a 'Mound', a label that tells you very little about its function. The later Cassini edition of the six-inch map depicts it as a small circular shaped mound, which at least suggests something was still discernible on the ground at that point. By the time satellite imagery caught up with the site, somewhere between 2011 and 2013, no surface remains were visible at all. The record was compiled by Fiona Rooney and uploaded to the national monuments database in November 2021, preserving the cartographic history of something the landscape itself has largely forgotten.

The site lies in rough upland pasture, which means the ground can be wet and uneven underfoot, particularly outside the summer months. There is no formal access, and the terrain demands sturdy footwear and a degree of patience with open mountain walking. The two neighbouring cairns recorded nearby are the more likely candidates for visible remains, and cross-referencing the Cassini-edition map with current satellite imagery before setting out would give the best sense of where to look. The absence of surface remains does not make this a frustrating destination so much as an instructive one: a place where the documentary record has outlasted the physical object, and where three old townland names scratched onto a hillside map are now the only reliable evidence that this boundary was ever marked at all.
