It is barely a metre high and roughly nine metres across, partially overgrown, and easy to mistake for nothing in particular. The word "possibly" does a lot of work in its official description.

A lime kiln, if that is what this is, would have been a practical and once-common feature of the rural Irish landscape. These were stone-built structures used to burn limestone at high temperatures, producing quicklime for fertilising fields, for mortar, and for whitewashing buildings. The circular form, the central hollow, and the rubble scatter are consistent with that kind of structure, though the site is too eroded to be certain. When the Ordnance Survey recorded it on their third-edition six-inch map in 1932, the mound measured closer to fifteen metres in diameter, suggesting that in the intervening decades the structure has continued to collapse inward and spread. The difference between that recorded dimension and what is visible today gives some sense of how quickly an unprotected earthwork can lose its shape to weather, grazing animals, and time.
