The stones number well over two hundred across two adjoining townlands, Timoney Hills and Cullaun, yet they follow no obvious pattern. An Inspector of National Monuments, surveying the group in 1936, noted that apart from one clearly defined stone circle in Cullaun, the remainder appear to be arranged on no particular system at all. That observation alone separates Timoney from the tidier narratives that usually accompany prehistoric monuments.

When the Inspector carried out his survey in 1934 to 1936, he counted 221 surviving stones, 173 in Timoney Hills and 48 in Cullaun, all of red sandstone or conglomerate and standing between roughly 0.9 and 1.8 metres above the ground. A later map published in the Archaeological Survey of Ikerrin recorded 245 stones in total, with 70 already removed by that point, along with five cairns that have since also disappeared. The attrition has continued. Of nine orthostats, meaning upright standing stones, recorded in one particular field, only seven could be located in recent survey work; the remaining two were presumably removed or levelled sometime after the 1930s. The stones themselves sit within the estate of Timoney Park, long associated with the Parker-Hutchinson family, whose 19th-century private burial ground lies roughly 83 metres to the north-west. That proximity to a landscaped Georgian estate is precisely what complicates the picture: archaeologists have noted that the setting raises genuine questions about whether some or all of the stones were erected in antiquity or were instead arranged as estate ornament in more recent centuries. The question has not been definitively resolved.
