Fulachta fiadh, the plural of fulacht fia, are Bronze Age cooking monuments found in their thousands across Ireland. The basic principle involved heating stones in a fire, dropping them into a water-filled trough until the water boiled, and using that heat to cook meat. What gets left behind is the spent, fire-shattered stone, and over repeated use these discarded heaps accumulate into the characteristic horseshoe-shaped mounds that survive to this day. Finding three of them clustered together, two adjoining and a third only twelve metres to the east, suggests this particular spot beside the stream was returned to repeatedly, perhaps over generations.

The westernmost mound is the most clearly defined, rising to 1.1 metres and measuring 9.7 metres in overall diameter. Its horseshoe shape opens toward the stream at the north-north-east, which makes practical sense given that proximity to water was essential to the whole operation. Large upright stone slabs protrude from the base of its southern side, and the composition of the mound is plainly visible: earth mixed through with fire-cracked stone, charcoal flecks, and charcoal nodules, the accumulated debris of many cooking episodes. The second mound, immediately to the east, is larger at 13 metres in diameter and less regular in outline, with a small flat-topped rise partially blocking its open northern end and two gaps of apparently recent origin at the south-west and south-east. The third, further east again, is also horseshoe-shaped, measuring roughly 8.9 metres by 10.5 metres and open at the north-west. All three lie within a complex of old field walls, placing them inside a landscape that was clearly organised and worked long after the monuments themselves were first built.
