The broader grouping to which they belong once numbered at least 245 stones spread across the townlands of Timoney Hills and Cullaun, along with five cairns, though by the time a detailed map was published in the Archaeological Survey of Ikerrin, some 70 stones and all five cairns had already been removed. One individual stone, recorded as 5A2 during a systematic survey conducted between 1934 and 1936, has since vanished entirely, leaving no surface trace.

When the Inspector of National Monuments documented the wider complex in 1936, he counted 221 survivors, describing them as "a most remarkable group." The stones, all of red sandstone or conglomerate, stood between roughly three and six feet in height, with the larger examples averaging around five feet. What struck him, beyond their sheer number, was the apparent absence of any governing layout. Unlike the tidy geometry of a stone circle or the clear processional logic of an avenue, these stones seemed to follow no particular system, with one notable exception: a single stone circle in the adjoining townland of Cullaun. The rest simply occupied the landscape in a loose, irregular scatter across the two townlands.

The uncertainty about their origins is not a minor footnote. The stones sit within the landscaped grounds of Timoney Park, the former estate of the Parker-Hutchinson family, and that association has prompted genuine scepticism among researchers about whether the arrangement dates to prehistory at all, or whether it might instead reflect the improving or ornamental ambitions of a landed estate. It is a question that has not been resolved, and it hangs over the site in a way that makes even the stones still standing quietly difficult to read.
