It is one of sixteen stones in this particular field that together formed a circular arrangement, the kind of prehistoric monument known as a stone circle, recorded as such in 1936. The field itself was known locally as the 'racecourse field', a name that gestures at a more recent past, and that detail sits uneasily beside the ancient origins these stones are presumed to have.

The stone belongs to a much larger and genuinely peculiar concentration of standing stones spread across two adjoining townlands, Timoney Hills and Cullaun. When the Inspector of National Monuments surveyed the area between 1934 and 1936, he counted 221 stones still in place, 173 in Timoney Hills and 48 in Cullaun, and mapped this one as stone 9P. A later survey published in the Archaeological Survey of Ikerrin recorded 245 stones in total, of which 70 had already been removed, along with five cairns that have since disappeared entirely. The Inspector noted in 1936 that the stones, all of red sandstone or conglomerate, stood between roughly 0.9 and 1.8 metres in height and did not appear to follow any obvious arrangement, with one exception: the clear circle in Cullaun to which this stone belongs. What makes the group unusual is not just its scale but a lingering question about its origins. The stones sit within the landscaped estate of Timoney Park, associated with the Parker-Hutchinson family, and that setting has led some researchers to wonder whether at least part of what looks like a prehistoric field monument might be a later, estate-era arrangement rather than something genuinely ancient. The doubt has never been fully resolved, which gives the whole scattered group an odd, unresolved quality that a straightforward prehistoric site would not have.
