The example at Carragraigue in North Cork is no exception: a low, partially overgrown mound sitting in rough grazing ground roughly 260 metres north-east of the local stream. What it lacks in visual spectacle it makes up for in the quiet specificity of its dimensions and arrangement. The mound measures 18.2 metres long, 26.1 metres wide, and stands 1.35 metres high, with three distinct openings, two facing north and one facing south, each roughly three to three and a half metres across.

A fulacht fia, sometimes rendered as fulacht fiadh in older scholarship, is essentially a burnt mound, the accumulated debris of a prehistoric cooking or heating site. The typical method involved heating stones in a fire, dropping them into a water-filled trough to bring the water to a boil, and repeating the process as stones cracked and were discarded. Over time, these shattered, fire-blackened stones built up into the characteristic horseshoe or irregular mounds that survive today, often near water sources as here, close to the Carragraigue stream. The openings visible in this mound likely correspond to the edges of a central trough or working area. Dating for such monuments generally falls within the Bronze Age, roughly 1500 to 500 BC, though the sites remained in sporadic use across a wide span of Irish prehistory. Notably, a second fulacht fiadh lies only about 75 metres to the north-east, suggesting that this particular stretch of the North Cork landscape saw repeated or sustained prehistoric activity rather than a single isolated episode.
