They cluster across the adjoining townlands of Timoney Hills and Cullaun, most of them cut from red sandstone or conglomerate, standing between roughly a metre and a metre and a half tall. There is no dramatic monument here, no single focal point; just an unsettling accumulation of upright slabs spread through rough pasture, some still standing, many long since toppled or removed entirely.

When the Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 stones still present across the two townlands, 173 in Timoney Hills and 48 in Cullaun. Of those, 12 in one field alone were upright and 23 were prostrate. He noted that the stones appeared to follow no particular system of arrangement, with the exception of one discernible stone circle in Cullaun. A later map published in the Archaeological Survey of Ikerrin recorded 245 stones in total, along with five cairns, a stone-built burial mound type found across prehistoric Ireland; by the time of that survey, 70 of the standing stones and all five cairns had already been removed. The stones occupy the grounds of Timoney Park, the estate of the Parker-Hutchinson family, and that association with a landscaped private estate has led some researchers to question whether the stones are genuinely ancient monuments or whether they were arranged, at least in part, as ornamental features during the estate's development. That question has not been definitively resolved. The site carries National Monument status, and individual stones continue to be catalogued, though dense scrub vegetation has made some of them impossible to physically relocate on the ground.
