The stones do not form the kind of deliberate geometric patterns seen at famous prehistoric sites; they seem, in the words of the Inspector of National Monuments writing in 1934, to follow no particular system at all, with the exception of one stone circle in Cullaun. What survives today is a much-reduced assembly. The particular stone recorded as 5S1 is modest enough on its own terms, a rectangular block of roughly 0.8 metres in height, oriented north to south along its long axis, set into the undulating ground of what was once a landscaped estate.

When the Inspector surveyed the area between 1934 and 1936, he counted 221 stones remaining across the two townlands, 173 in Timoney Hills and 48 in Cullaun. He noted that all were of red sandstone or conglomerate, ranging from about three to six feet above ground, with the larger examples averaging around five feet. A later map published in the Archaeological Survey of Ikerrin by Stout in 1984 recorded 245 stones in total, but indicated that 70 had already been removed, along with five cairns, which are also now gone. The progressive loss makes the site difficult to read even in specialist terms. Complicating matters further is the fact that the stones sit within the landscaped grounds of the Parker-Hutchinson estate at Timoney Park, a circumstance that has led some researchers to question whether the monuments are genuinely prehistoric or whether some or all of them were arranged, or rearranged, during the improvement of the estate grounds. That question has not been resolved, which gives the whole collection an ambiguity that purely ancient sites rarely have.
