No alignments, no clear geometry, no apparent astronomical purpose. Just stones, standing at various heights between roughly one and one and a half metres, spread across two adjoining townlands in a way that has puzzled and intrigued observers for decades. One of those stones, a rectangular slab about a metre tall, sits on what was once the landscaped grounds of Timoney Park, oriented on its long axis from north to south, with no packing stones around its base to indicate how it was set in place or when.

When the Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 stones still standing or lying prostrate across the townlands of Timoney Hills and Cullaun, and described the group as "a most remarkable" collection. A later map published in the Archaeological Survey of Ikerrin, compiled by Stout in 1984, recorded as many as 245 stones in total, though by that point 70 had already been removed, along with five cairns that have since disappeared entirely. The stones are all of the same geological material, suggesting a common origin, but beyond that, the questions multiply. The Inspector noted only one arrangement that seemed deliberate, a stone circle in the Cullaun townland, while the rest appeared to follow no particular system. There is an additional complication: the stones sit within the bounds of the Parker-Hutchinson estate of Timoney Park, and that association with a landscaped private estate has led some to question whether all of these monuments are genuinely prehistoric, or whether some may have been arranged or introduced during the improvement of the estate grounds in more recent centuries.

The stone recorded here as 5F on the 1934 survey map is one of eleven identified within a single field of the estate. Two stones in that same field were already recorded as prostrate during the 1930s survey, suggesting ongoing loss even at the point when formal attention was first paid to the group. The site carries National Monument designation, number 353, but the broader questions about what exactly is being protected, and how old the arrangement truly is, remain unresolved.
