What makes the site genuinely puzzling, beyond sheer numbers, is that the stones appear to follow no obvious arrangement. They are not aligned, not symmetrically spaced, and not grouped into any pattern that archaeologists have been able to decode, save for one stone circle identified in Cullaun. Ranging from roughly three to six feet in height, and all cut from the same red sandstone or conglomerate, they have an unsettling uniformity that raises more questions than it answers.

When the Inspector of National Monuments surveyed the site 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. By the time Stout's Archaeological Survey of Ikerrin was published in 1984, the picture had grown more complicated: a map in that survey recorded 245 stones in total, of which 70 had already been removed, along with five cairns that had also disappeared. The single stone covered by this record sits alongside a recumbent stone or possible rock outcrop immediately to its north. But the most unsettling detail about Timoney is not the losses; it is the doubt surrounding the stones' origins altogether. The site lies within the landscaped estate of Timoney Park, the former grounds of the Parker-Hutchinson family, and that context has led some to question whether these are genuinely prehistoric monuments or whether at least some were placed here as estate features, the kind of romantic antiquarian landscaping fashionable among Anglo-Irish landowners in the eighteenth and nineteenth centuries. No definitive answer has been established, which leaves Timoney suspended between prehistory and performance, a field full of stones that may be ancient, may be theatre, or may be some uneasy combination of both.
