The mound is a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland, typically Bronze Age in date. The standard interpretation holds that stones were heated in a fire, then dropped into a water-filled trough to bring it to a boil, and the discarded burnt stone gradually accumulated into the characteristic mound shape. This example is a well-preserved one: roughly 24.8 metres northeast to southwest and 23.8 metres across, standing on average 1.8 metres high and reaching 2.6 metres at its highest point to the west-northwest. The trough area, measuring around nine metres by four, opens to the southwest.

What makes this particular site quietly unusual is the density of archaeology compressed into a small area. Two further possible fulachtaí fia lie within sixty metres to the west and southwest respectively, and a small, dilapidated wedge tomb, a type of Neolithic or Early Bronze Age megalithic burial monument, sits centrally between the three mounds, as though placed there deliberately, though any such reading would be speculation. The site was recorded on the 1915 Ordnance Survey six-inch map, indicated by hachuring. Tucked into the northern side of the main fulacht fia mound, presumably added at some much later date, is a small limekiln, a structure used to burn limestone to produce quicklime for agricultural or building purposes. Its incorporation into the prehistoric mound is the kind of incidental layering that accumulates on a site used and reused across centuries without anyone necessarily registering the strangeness of it.
