There are hundreds of them, they follow no obvious pattern, and nobody is entirely certain how old they are.

When the Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 stones still upright or in place across the two townlands, describing them as "a most remarkable group" arranged on no particular system, with the exception of one stone circle in Cullaun. All are of red sandstone or conglomerate and stand, or once stood, between roughly 0.9 and 1.8 metres above ground. A later map published in the Archaeological Survey of Ikerrin recorded as many as 245 stones in total, along with five cairns, though by that point 70 stones and all five cairns had already been removed. The losses have continued since: the specific stone recorded as 5X on the 1934 to 1936 survey map, one of a subgroup of 46 in a single field, has left no surface trace at all. What complicates the picture further is that the stones sit within the landscaped grounds of Timoney Park, the former Parker-Hutchinson estate. That setting has led some researchers to question whether all or some of the stones were arranged or introduced during the improvement of the estate grounds, rather than representing a prehistoric monument in the conventional sense. The uncertainty sits unresolved. The sheer number of stones, their consistent material, and their distribution across two townlands suggest something more than Georgian garden ornament, but the question of origin has never been fully answered.
