It was recorded, measured, and described in 1837, and then, in the way of such things, it quietly slipped from precise knowledge. Its location has never been firmly established since.

The record comes from the Ordnance Survey Letters of 1837, a remarkable series of fieldwork notes compiled as surveyors moved across Ireland documenting antiquities alongside topographical detail. The entry describes a cromleac, a term used at the time for what we would now generally call a portal tomb or dolmen, a megalithic burial structure consisting of large upright stones supporting a capstone. This particular example was modest in scale: the capstone measured seven feet long (2.13 metres), two and a half feet broad and the same in thickness. It rested at a slight southward incline, propped on a cluster of small stones that lifted it roughly a foot above the ground surface. What makes the description especially useful is the note about its enclosure: the diameter of the surrounding stone circle was not much more than the length of the capstone itself, making it a compact and tightly bounded arrangement. This detail was later cited by Herity in 2001, suggesting the record continued to circulate among researchers even without a firm location to attach it to.

Because the site has not been precisely located, there is no straightforward way to visit it. The general area southeast of Ballybetagh House, in the Dublin Mountains, is the only geographic anchor available. Anyone walking that landscape with the 1837 description in mind should look for a long, flat stone of roughly the dimensions given, lying at a low angle over smaller supporting stones, possibly within or near a faint circular arrangement on the ground. The monument may have been disturbed, partially buried, or obscured by vegetation in the intervening nearly two centuries. It is less a destination than an open question, the kind of small puzzle that fieldwork occasionally resolves by accident.
