It is not a ruin in any conventional sense, nor a building reduced to rubble. It is simply a cairn, a deliberate prehistoric accumulation of stones, and at 21 metres long, nearly 10 metres wide, and standing over two metres high at its tallest point, it is emphatically too substantial to have been thrown up by a farmer clearing a field.

The cairn is aligned roughly northwest to southeast, its sides steep enough to be immediately noticeable against the gently rolling ground around it. At the southeastern end of the flattened top, there is a hollow that may indicate a collapsed internal chamber, of the kind sometimes found beneath prehistoric burial cairns, where a stone-built space once held human remains or offerings before the weight of the structure gradually pressed it inward over centuries. All the stones are sandstone, averaging around 20 centimetres across, loosely piled rather than mortared or coursed. What makes the site stranger still is that it is not alone: a closely comparable cairn sits 340 metres to the south-southeast, suggesting that whatever purpose these structures served, it was considered worth repeating in the same landscape. From the top of the mound, the Galtee Mountains are visible to the north-northeast, and another recorded cairn on those slopes lies roughly 5.5 kilometres away in the same direction, hinting at a broader prehistoric presence across this stretch of Tipperary that is easy to walk past without recognition.
