The evidence here is modest but legible to those who know what to look for: burnt material showing at the base of a field fence, with the spread extending some fourteen metres northward from it, running parallel to a stream on the site's southern edge.

Fulachtaí fia, to use the plural, typically consist of a horseshoe-shaped mound of heat-shattered stone, the debris from a process in which rocks were heated in a fire and then dropped into a water-filled trough to bring the water to a boil. The proximity to a stream is characteristic; water supply was essential to the process, whatever exactly that process was. Debate has run for decades over whether these sites were primarily for cooking, bathing, textile preparation, or some combination of uses. What gives the Kilberrihert site an added layer of interest is its context: two further fulachtaí fiadh lie within roughly fifty and seventy metres to the east along the same stream. The clustering of three such monuments in close proximity along a single watercourse is a reminder that these were not isolated or accidental features of the landscape, but part of a pattern of repeated, deliberate activity in the same locality during prehistory.
