A fulacht fia is essentially a Bronze Age cooking site, the mound itself made up of fire-cracked stones that were heated and dropped into a water-filled trough to bring it to the boil. The process left behind great quantities of shattered, heat-blackened stone, and over centuries these accumulated into the distinctive humped shapes that survive across thousands of locations in Ireland today.

The mound at Carragraigue measures just over nineteen metres in length and nearly sixteen metres in width, rising to a height of around a metre. Its opening, some five and a half metres wide, faces north, which is somewhat unusual given that many examples open towards a water source dictated purely by local topography. What makes the site quietly interesting beyond its own dimensions is that a second fulacht fia lies roughly seventy-five metres to the south-west, suggesting this particular stretch of ground saw repeated or perhaps simultaneous use. Whether the two monuments were contemporary with one another is difficult to say without excavation, but their proximity hints at a landscape that was, at some point in the Bronze Age, a place of organised activity rather than isolated, opportunistic cooking.
