The particular stone in the townland of Cullaun, now lying flat and broken, measuring just over one and a half metres in length, is only one piece of a much stranger puzzle. When an Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 stones still standing or identifiable across the two adjoining townlands, and noted that even then a significant number had already been removed. A later map, published in the Archaeological Survey of Ikerrin by Stout in 1984, recorded 245 stones in total, of which 70 had been taken away, along with five cairns, a type of stone mound typically associated with burial, that had also since disappeared.

The stones themselves, all of red sandstone or conglomerate, ranged from roughly 0.9 to 1.8 metres in height, with the larger examples averaging around 1.5 metres. The 1936 inspector's account noted that they did not appear to follow any obvious arrangement or pattern, with one exception: a stone circle visible in the Cullaun townland. That combination, scores of individual orthostats, the term used for the upright slabs themselves, scattered without apparent system alongside a single formal circle, makes the group genuinely difficult to interpret. Adding to the uncertainty is the fact that the stones sit within the landscaped grounds of Timoney Park, the estate of the Parker-Hutchinson family, whose private burial ground lies less than 100 metres to the north-north-west. That proximity to a 19th-century landed estate has led some to question whether all the stones are genuinely ancient, or whether some may have been arranged or introduced during the landscaping of the demesne. The question has not been resolved.
