During routine archaeological testing ahead of a housing development in the townland of Brigown, excavators found exactly this kind of spread, the characteristic signature of a burnt mound. Burnt mounds are among the most common prehistoric monument types in Ireland, yet they remain genuinely puzzling. They consist of heat-shattered stones, typically created by heating rocks in a fire and plunging them into water to boil it, accumulated over time into a low mound or spread alongside a trough or pit. What they were used for, whether cooking, bathing, industrial processing, or something else entirely, is still debated.

Excavation at Brigown revealed a layer of heat-shattered stones and charcoal-enriched soil measuring roughly three metres by two metres, though only around eight centimetres deep, suggesting either a relatively modest episode of use or that much of the original deposit had been lost. Beneath this layer, four small circular stake-holes were recorded, each with vertical sides and a rounded base, and each roughly seven centimetres in diameter and fourteen centimetres deep. The excavator, working from the evidence published by O'Callaghan in 2006, proposed that these stake-holes may represent the remains of a wind-break, a light structure of upright stakes that would have sheltered whatever activity was taking place at the site from the elements. It is a modest but telling detail: the people who used this spot were not simply lighting a fire and walking away, but were making deliberate arrangements for comfort or efficiency.
