The sheer number is what sets Timoney Hills apart. Most megalithic landscapes in Ireland involve handfuls of stones, perhaps a dozen at most. Here, stones of red sandstone and conglomerate spread across two adjoining townlands in a pattern that, according to those who have studied them, appears to follow no particular system, with the single exception of one stone circle in the townland of Cullaun.

When the Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 survivors, 173 in Timoney Hills and 48 in Cullaun, and judged them a most remarkable group. The stones stand or stood between roughly 0.9 and 1.8 metres above ground, and are all of the same geological material. A later map published in the Archaeological Survey of Ikerrin, compiled by Stout in 1984, recorded 245 stones in total, of which 70 had already been removed, along with five cairns that have since disappeared entirely. The stone documented here, one of 17 identified in a single field, is subrectangular in plan, measures 1.5 metres high, and is orientated east to west on its long axis, with no packing stones visible around its base. It sits within the landscaped grounds of Timoney Park, the former estate of the Parker-Hutchinson family, and that setting introduces a note of genuine uncertainty. Whether these are prehistoric monuments in the conventional sense, or whether the estate's landscaping history played some role in their arrangement or survival, has not been fully resolved. That ambiguity does nothing to diminish the strangeness of the place, but it does complicate the easy assumption that antiquity alone explains what you are looking at.
