It would be easy to walk past without a second glance. The mound is barely a mound at all, reaching only twenty to thirty centimetres at its highest points, at its northern and southern ends, with an uneven, almost hollow surface between them. What gives it away are the details visible at the southern end: small angular fragments of stone, dark grey soil, and flecks of charcoal scattered on the surface.

These are the hallmarks of a burnt mound, a type of prehistoric cooking site found widely across Ireland and Britain. The general principle is straightforward: stones were heated in a fire and then dropped into a water-filled trough to bring the water to boiling point, allowing meat or other food to be cooked. Over time, the cracked and shattered stones were discarded, accumulating into the distinctive horseshoe or oblong mounds that survive today. This particular example, roughly ten metres north to south and five and a half metres east to west, is in an oblong form and was partly levelled at some point in its past, which accounts for its unusually flat profile. It came to attention only in March 2015, when ground works for a forestry plantation in the area were under way; it was first noted by Michael Cox during those works. An exclusion zone was subsequently established to protect the mound from further disturbance.
