What makes the site genuinely puzzling, beyond its sheer scale, is that the stones appear to follow no obvious arrangement. There is no clear alignment, no discernible pattern, with the exception of a single stone circle identified in Cullaun. They simply stand, or once stood, distributed across the landscape in a manner that has resisted tidy interpretation.

When the Inspector of National Monuments surveyed the site between 1934 and 1936, 221 stones were still recorded as present, 173 in Timoney Hills and 48 in Cullaun. Even then, the inspector noted that a number had already been eliminated. A later map published in the Archaeological Survey of Ikerrin counted 245 stones in total, of which 70 had been removed, along with five cairns that have since disappeared entirely. The surviving stones are all of red sandstone or conglomerate and ranged from roughly three to six feet in height, with the larger ones averaging around five feet. The whole group sits within the landscaped grounds of Timoney Park, the former estate of the Parker-Hutchinson family, and that setting introduces a complication that archaeologists have not fully resolved: the possibility that at least some of the stones were arranged or repositioned during the landscaping of the estate, which throws genuine doubt on whether all of them are ancient at all. One stone recorded on the 1934 to 1936 map as stone 3S may in fact be a large natural boulder, not a deliberately placed monument. The group holds the designation of National Monument No. 353, but the question of what exactly is being protected remains, in part, open.
