The one at Knockalohert, in County Cork, offers little to the eye: a spread of heat-shattered stones and charcoal-darkened soil, softened under a covering of grass and rushes, sitting in boggy ground on a gentle south-east-facing slope. Even its full extent could not be determined when it was recorded.

Burnt mounds, known in Irish archaeology as fulachta fiadh, are typically Bronze Age in origin, though some date to other periods. They tend to cluster near water and are generally interpreted as the remains of outdoor cooking or food-processing sites, where stones were repeatedly heated in fire and then dropped into water-filled troughs to bring them to the boil. The repeated fracturing of those stones under thermal stress is what produces the characteristic scatter of shattered rock that defines the site type. The charcoal-enriched soil at Knockalohert is consistent with this pattern, the residue of repeated burning episodes over what may have been a long period of use. The site lies in ground that had been recently planted with trees at the time of recording, which may complicate both its visibility and its preservation.
