What makes the site genuinely unusual is not just the number of stones but their arrangement, or rather the apparent lack of one. They do not align neatly, they do not describe a procession or an avenue, and with the exception of one stone circle in Cullaun they seem to follow no discernible pattern at all, which sets them apart from the more legible prehistoric landscapes that tend to attract attention.

When the Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 surviving stones, 173 in Timoney Hills and 48 in Cullaun, and described them as a most remarkable group. All were of red sandstone or conglomerate, standing or once standing between roughly 0.9 and 1.8 metres above ground. A later survey published in the Archaeological Survey of Ikerrin by Stout in 1984 mapped 245 stones in total, but recorded that 70 had already been removed, along with five cairns, a cairn being a mounded heap of stones typically associated with prehistoric burial. The particular stone recorded here, marked as stone 4P on the 1936 map, is a modest rectangular slab measuring 0.71 metres high, oriented east to west along its long axis, with no packing stones visible around its base. That last detail matters more than it might seem: the absence of packing stones, which would normally be used to stabilise a deliberately erected monument, is one of several details that have led some researchers to question whether these stones are genuinely ancient at all. Their location within the landscaped estate of Timoney Park, associated with the Parker-Hutchinson family, raises the possibility that at least some of the stones were arranged or repositioned during estate improvement works rather than in prehistory. The question has not been definitively resolved.
