Spread across undulating pasture on the grounds of Timoney Park in County Tipperary, they form one of the largest concentrations of standing stones in Ireland, yet they remain largely unknown outside specialist circles. When the Inspector of National Monuments surveyed the site in 1934 to 1936, he counted 221 stones still in place, distributed between the townlands of Timoney Hills and Cullaun. A later map, published in the Archaeological Survey of Ikerrin in 1984, recorded 245 stones in total, of which 70 had already been removed, along with five cairns that have since disappeared entirely.

The stones themselves are all of red sandstone or conglomerate, ranging from roughly 0.9 to 1.8 metres in height, with the larger examples averaging around 1.5 metres. The Inspector noted in 1936 that they appear to follow no particular arrangement, with one exception: a single stone circle located in the Cullaun townland. That absence of obvious pattern is itself part of what makes the site so puzzling. Standing stones, which are upright single stones of prehistoric origin found widely across Ireland, usually prompt attempts to read them as alignments or ceremonial arrangements, but Timoney resists easy interpretation. Adding a further layer of uncertainty is the fact that the stones sit within the landscaped estate of Timoney Park, the former Parker-Hutchinson estate, and that setting has led some to question whether all of them are genuinely ancient or whether some may have been arranged or repositioned during the landscaping of the demesne grounds. The question has not been fully resolved.
