Sixty-six metres east of a burnt mound in Loughlion, County Kildare, lies a pit that is easy to overlook and almost impossible to date with certainty. It is small, oval, and barely a third of a metre deep, yet the careful way it was filled in over time suggests it was not simply dug and forgotten. Only the uppermost of its three fills contained any charcoal, meaning whatever burning or heat-related activity created this feature had already ceased before the pit was finally covered over.

The site, designated Site 8 during excavation, was investigated by archaeologist Thaddeus C. Breen under licence number 01E0846. Beside the main oval pit, measuring 0.9 metres by 0.5 metres, a smaller pit was found containing a whetstone at its base, a hand-held sharpening stone used to hone bladed tools. Two further small pits, a possible post-hole, and traces of spade cultivation furrows were identified nearby. Taken together, these features suggest a modest working area of some kind, associated in ways that remain unclear with the burnt mound 66 metres to the west. Burnt mounds are among the most common prehistoric monument types in Ireland, typically consisting of mounds of fire-cracked stone accumulated beside a trough or pit where water was repeatedly heated, probably for cooking, bathing, or craft processes such as leather-working. Whether this smaller cluster of pits formed part of the same activity, or represents a separate episode of use in the same landscape, is not something the excavation resolved.
