It is the kind of feature that passes entirely unnoticed on the surface, and it took deliberate archaeological investigation to confirm what was there at all.

In April 2021, archaeologist C. McLoughlin carried out testing at the site under licence 21E0025, uncovering an oval feature measuring roughly 2.5 metres by between one and 1.2 metres, and no deeper than 0.4 metres at its most pronounced point. Kilns of this general type were used for a range of purposes in rural Ireland, from drying grain to burning lime for agricultural or building use, and the physical evidence recovered here fits that working tradition closely. The fill consisted of dark brown silty clay containing charcoal fragments, sitting over a distinctly charcoal-rich seam beneath, the residue of whatever fuel and heat had once been applied. The positioning at the elevated northern end of the ridge would have made practical sense, offering some exposure to airflow and a degree of visibility across the surrounding ground.
