This is a fulacht fia, one of the most common prehistoric monument types in Ireland, and also one of the least dramatic to look at. What you see above ground is essentially the debris of an ancient cooking method: stones were heated in a fire, dropped into a water-filled trough to bring it rapidly to a boil, and the cracked, heat-spent stones were then discarded into a horseshoe-shaped mound around the trough. Over centuries, that discard heap is often all that survives.

The mound at Curraduff measures approximately six metres east to west and four metres north to south, with a further spread of burnt material noted immediately to its south. The proximity to a natural spring is typical of the type; reliable, clean water was essential to the whole process. What makes the location quietly interesting is that it does not stand alone. A second fulacht fia lies roughly 150 metres to the south-southwest, suggesting that this stretch of the Curraduff landscape saw repeated or sustained use across some portion of the Bronze Age. Whether the two sites were used at the same time or represent activity separated by generations is the kind of question the field evidence, a mound of spent stone in a pasture, cannot easily answer on its own.
