Roughly oval in shape, measuring just 1.3 metres by 0.9 metres and less than a metre deep, it was filled with burnt material, and the clay surrounding it had been reddened by sustained heat. Whatever happened here, fire was central to it, and yet almost nothing survived to explain why.

The pit came to light during excavations led by archaeologist Brendán Ó Riordáin as part of the Arklow bypass road scheme, under excavation licence 97E0083. It was designated Site N within the broader project, suggesting it was one feature among many uncovered along the road corridor. The sole find recovered from the pit was a single, very thin flake of roughly worked flint. A fulacht fiadh, the term used for a type of prehistoric burnt mound typically associated with the heating of water using fire-cracked stones, might come to mind as a comparison, though there is no direct evidence here to support that interpretation. What the pit represents functionally remains open. The reddened clay indicates repeated or intense burning in place rather than the deposit of material burned elsewhere, but beyond that, the feature keeps its purpose largely to itself. A single flint flake, too slight to be a formal tool, is all it offered up.
