Or so it appeared. The particular stone designated 5L on a 1934 to 1936 survey map has since vanished entirely, leaving no surface trace, and it is not alone in its disappearance.

When the Inspector of National Monuments surveyed the area in the mid-1930s, he counted 221 stones still upright or prostrate across two adjoining townlands, Timoney Hills and Cullaun, with 173 in the former and 48 in the latter. The stones, all of red sandstone or conglomerate, ranged from roughly three to six feet in height, with the larger examples averaging around five feet. The inspector noted that they did not appear to follow any deliberate arrangement, with one exception: a recognisable stone circle in Cullaun. By the time Geraldine Stout published the Archaeological Survey of Ikerrin in 1984, the count had risen to 245 on record, but 70 of those had already been removed, along with five cairns, stone mounds that in an Irish prehistoric context often served as burial monuments. Precisely what the broader group represents prehistorically has never been firmly established, and the question of authenticity adds a further layer of uncertainty. The stones sit within the parkland of the Parker-Hutchinson estate at Timoney Park, and their location on a deliberately landscaped demesne has led to genuine doubt about whether all or some of them were placed there in antiquity, or whether an estate owner at some point arranged or augmented them as a feature of ornamental grounds. That ambiguity has never been fully resolved.
