The mound is roughly oval, about nine metres east to west and six and a half metres north to south, rising only three-quarters of a metre above the surrounding ground. Beneath the grass lies a mass of burnt material, the characteristic signature of prehistoric cooking activity.

This is a fulacht fia, a type of monument found in the hundreds across Ireland and dating most commonly to the Bronze Age. The basic principle involved heating stones in a fire and dropping them into a water-filled trough to bring it to a boil; the cracked and fire-shattered stones were then discarded in a heap, which over time built up into exactly the kind of horseshoe-shaped or oval mound visible here. The cultivation ridges running east to west across the surface suggest that at some later point this patch of ground was worked as farmland, the mound repurposed or simply absorbed into the agricultural routine without much ceremony. What makes this site particularly notable is its immediate proximity to a second fulacht fia, recorded just to the east, which raises the possibility that this stretch of riverbank saw repeated or sustained use over time.
