At its fullest recorded extent, the group amounted to at least 245 stones spread across two adjoining townlands, Timoney Hills and Cullaun, with five cairns also noted before their removal. Yet for all that density, no clear arrangement has ever been identified. When the Inspector of National Monuments surveyed the group in 1934 to 1936, he noted that the stones did not appear to follow any particular system, with the single exception of an obvious stone circle in Cullaun. That absence of pattern, in a concentration this large, is itself unusual.

The stones are all of red sandstone or conglomerate and were recorded as standing between roughly 0.9 and 1.8 metres in height, with the larger examples averaging around 1.5 metres. By the time of the 1936 survey, 221 stones remained, 173 in Timoney Hills and 48 in Cullaun, though even then several had already been removed or had fallen prostrate. A later study published as the Archaeological Survey of Ikerrin by Stout in 1984 recorded 245 stones in total, of which 70 had been taken away, along with the five cairns. The particular stone described here now survives as a low, broken fragment barely 0.4 metres high, with no packing stones visible around its base to confirm how it was originally set into the ground. That last detail matters, because the entire group sits within the landscaped estate of Timoney Park, historically the Parker-Hutchinson estate, and the possibility that some or all of the stones were arranged or relocated as estate ornament during the eighteenth or nineteenth century has never been fully resolved. Whether these are ancient monuments shaped by later interference, or something assembled more deliberately by estate improvers working with a romantic eye, remains genuinely open.
