At their peak count, over two hundred stones were recorded across two neighbouring townlands, with no obvious alignment, no clear pattern, and a question hanging over the entire site that has never been fully resolved: are they genuinely ancient, or something else entirely?

When the Inspector of National Monuments surveyed the area in 1934 to 1936, he recorded 221 stones still standing, 173 in the townland of Timoney Hills and a further 48 in the adjoining townland of Cullaun. He noted that the stones appeared to follow no particular system, with one exception: a single recognisable stone circle in Cullaun. The stones themselves range from roughly 0.9 to 1.8 metres in height and are all of red sandstone or conglomerate, suggesting a shared geological source and, potentially, a shared origin. By the time Stout's Archaeological Survey of Ikerrin was published in 1984, the total mapped had risen to 245, but 70 of those had already been removed, along with five cairns that had also disappeared. The Inspector's phrase, that the remainder formed "a most remarkable group", has the flavour of measured astonishment, the kind a field surveyor allows himself when the scale of something is hard to process.

The complication is this: the stones sit within the landscaped estate of Timoney Park, once the property of the Parker-Hutchinson family, and that setting has led some to question whether the monuments are prehistoric at all, or whether they were arranged, augmented, or partly invented during the era of ornamental estate landscaping. The stone recorded as 5G2 on the 1934 to 1936 map, one of 46 in its particular field grouping, has left no visible surface trace at all. Whether it was removed, buried, or simply never as permanent as it appeared, nobody has said definitively.
