The feature belongs to a category of prehistoric monument known as a burnt mound, one of the most common yet least understood archaeological site types in Ireland. These accumulations of heat-shattered stone are thought to represent the debris of repeated heating, where rocks were fired and then dropped into water-filled troughs, possibly for cooking, bathing, or industrial processes. They tend to cluster near water sources, and this one is no exception, sitting adjacent to a stream that was already mapped on the first edition six-inch Ordnance Survey of 1839.

The site came to light on 26 June 2007, when Bernice Molloy of Gowen and Co. Ltd. carried out a pre-development field inspection on behalf of the National Roads Authority, ahead of construction work on the M8 motorway. She recorded an area of burnt stone measuring approximately three metres north to south by two metres, lying in ground that remains waterlogged and subject to flooding. As it fell outside the road-take area, no further intervention was required, and the mound was left undisturbed. That narrow margin of geography is, in practical terms, the reason it still exists.
