It is not much to look at: roughly seven metres north to south, five metres east to west, and rising no more than 1.2 metres at its highest point. But beneath its sod covering lies a mixture of charcoal-rich earth and heat-shattered stone, the characteristic signature of a fulacht fia, and one that has been quietly accumulating its secrets since prehistoric times.

A fulacht fia is a type of burnt mound found widely across Ireland and Britain, generally interpreted as an outdoor cooking site, though theories about their use range from brewing to bathing to textile processing. The typical arrangement involves a timber-lined trough filled with water, into which stones heated in a nearby fire were dropped to bring the water to a boil. Over repeated use, the cracked and spent stones were discarded to the sides, gradually building up the horseshoe-shaped or oval mounds that survive today. At Creggyconnell, no definite trace of a trough has been identified, which is not unusual given how thoroughly these features can be obscured by later ground movement and vegetation. What remains is the mound itself, its flat top still legible, its scarped northern edge growing taller as it descends with the natural slope toward the bay. A further east-west scarp, about two metres high and eleven metres to the north, now marks the boundary between farmland and foreshore, giving some sense of how the landscape has been shaped and divided over the centuries around this much older feature.
