These features, known in Irish as fulachta fiadh, are among the most common archaeological monument types in Ireland, yet they remain easy to overlook. The typical fulacht fiadh consisted of a trough, usually timber-lined or stone-lined and sunk into the ground near a water source, into which heated stones were dropped to bring the water to a boil. The shattered, fire-cracked stones discarded after each use gradually accumulated into a horseshoe-shaped mound around the trough. Thousands of these mounds survive across the Irish landscape, most dating from the Bronze Age, roughly 1500 to 500 BC.

This particular example came to light not through excavation but through accident. Drainage works carried out in 1979 and 1980 cut through the site, exposing a layer of burnt material roughly 0.4 metres deep in the section of the drain. Local knowledge held that a low mound had existed on the spot before the drainage work altered the ground, standing somewhere between 0.3 and 0.6 metres in height. That mound is now gone or greatly reduced, but the burnt material visible in the drain profile confirms what the landscape had quietly preserved for perhaps three millennia, a place where people repeatedly gathered water, heated stones, and cooked beside a stream that has been running through this part of North Cork ever since.
