In a pasture field near Jigginstown in County Kildare, a prehistoric cooking site that was once a visible mound has effectively vanished from the surface, leaving behind little more than a patch of wet, rushy ground as its only clue. That kind of quiet disappearance is itself part of the story of fulachtaí fia, the ancient burnt-mound sites found in their thousands across Ireland. Typically Bronze Age in origin, they consist of a horseshoe-shaped mound of fire-cracked stones, the discarded debris from a simple but effective cooking method: stones were heated in a fire and dropped into a water-filled trough to bring it to a boil, then used to cook meat. The cracked, spent stones were raked aside after each use, building up the characteristic curved mound over time.

When the Jigginstown site was recorded in 1985, it presented as a horseshoe-shaped mound roughly six metres across on its north-south axis and about a metre in height, open towards the south in the typical fashion. By 2000, no obvious surface trace remained. The land had been drained with a plastic field-pipe installed just to the north of the site, and while this had altered the immediate hydrology, the ground to the south-east was still noticeably wet and rush-covered, suggesting that the underlying conditions which originally attracted a prehistoric community to this spot had not entirely been engineered away. The proximity to a small, north-west-flowing stream some thirty metres to the south reinforces the logic of the location; water access was essential to how these sites functioned. Despite the surface erasure, sub-surface features are considered likely to survive intact beneath the pasture.
