The trouble is that nobody can quite agree whether this particular arrangement of stones was ever put there by human hands at all. Sitting in rocky pasture on a north-west-facing slope, roughly 80 metres west-south-west of the Loughgur Cross, the structure measures 2.13 metres in length and between 1.22 and 1.83 metres in width, with a capstone about 30 centimetres thick. It is the kind of thing that catches the eye and invites a story, but the record around it is conspicuously thin.

The earliest written description comes from Croker in 1833, who noted the tabular stone and its three supports as though reporting something that deserved attention. Over a century later, however, O'Kelly assessed the site in 1944 and was sceptical, suggesting the stones were simply natural outcrops rather than a deliberate construction. That doubt has proved persistent: the site does not appear on any Ordnance Survey historic maps, was invisible in aerial imagery taken between 2005 and 2013, and was excluded entirely from the Megalithic Survey of Co. Limerick compiled by De Valera and Ó Nualláin in 1982, which recorded neither it as a confirmed monument nor even as a site worth watching. In 2002, archaeologist Frank Coyne opened six machine-cut trenches in the field immediately to the south, investigating it ahead of a possible dwelling. Each trench ran 20 metres long and 1.5 metres wide, dug down to the natural silty clay. Nothing was found. The structure itself sits within a remarkably dense cluster of monuments: the Carraig Aille stone forts lie 235 metres to the north, two crannóga, artificial island dwellings, known as the Balie Islands sit 550 metres to the north-west, and the Leagaun standing stone is only 90 metres to the south-west.

Access to the site is through rocky pasture, so appropriate footwear matters. The slope faces north-west, which means the light in the afternoon can be useful for reading the ground surface. Because the structure does not appear on standard maps and evades aerial photography, finding it requires careful use of the monument reference coordinates rather than any marked path or signpost. Given the ambiguity about its origins, visitors should resist the urge to read it as a confirmed prehistoric tomb; the more honest experience is standing in front of something genuinely unresolved, surrounded by a landscape where the authentic and the accidental sit uncomfortably close together.
