What survives today is remarkable enough; what was once here was extraordinary. A survey published in the Archaeological Survey of Ikerrin recorded 245 standing stones across the two townlands, along with five cairns, a burial monument type consisting of a mound of stones. By 1984, when that survey appeared, 70 of the stones had already been removed, and the cairns were gone entirely.

When the Inspector of National Monuments visited and mapped the site in 1934 to 1936, 221 stones remained, 173 in Timoney Hills and 48 in the adjoining townland of Cullaun. His description at the time was unambiguous: he called them "a most remarkable group." All were of red sandstone or conglomerate, standing between roughly 0.9 and 1.8 metres above ground, and they appeared to follow no obvious arrangement, with the single exception of one stone circle in Cullaun. The particular stone recorded here, marked as stone 3T on his map, measures 1.4 metres high, is subrectangular in shape, and is oriented on a north-south axis. There are no packing stones visible around its base, which is the kind of detail that archaeologists look for when trying to confirm that a stone was deliberately erected in antiquity rather than placed more recently.

That absence of packing stones points to a complication that shadows the entire site. The stones sit within the landscaped grounds of Timoney Park, the estate of the Parker-Hutchinson family, and this has led some researchers to question whether the monuments are genuinely prehistoric or whether, at least in part, they reflect the romantic enthusiasm for ancient-looking landscapes that was fashionable among Anglo-Irish estate owners in the eighteenth and nineteenth centuries. No firm answer has been established, and the uncertainty itself is part of what makes Timoney Hills so quietly unsettling to think about, a field full of stones that may be thousands of years old, or may be something else entirely, or may be both at once.
