To the untrained eye it looks like nothing more than a slight rise in the turf, but it marks a fulacht fia, one of the most common yet persistently mysterious monument types in the Irish archaeological landscape. These sites, found in their thousands across Ireland, are generally interpreted as Bronze Age cooking places, where stones were heated in fire and then dropped into a water-filled trough to bring it to the boil. The broken, fire-cracked stone that accumulated over repeated use formed a distinctive horseshoe-shaped mound, and it is exactly this kind of spread that survives here.

The positioning of the site is characteristic. Fulachtaí fia are almost always found close to water, whether a stream, a spring, or, as here, low-lying marshy ground. The association makes practical sense: a ready water supply was essential to the whole process. The burnt mounds of north Cork have been recorded as part of wider efforts to document the region's prehistoric remains, and the Keeltane example, though modest in description, fits neatly into a pattern repeated across the county and beyond. Most fulachtaí fia date to the Bronze Age, roughly between 1500 and 500 BC, though the form persisted in some areas into later periods.
