A fulacht fia is, in essence, a prehistoric cooking or hot-water site, typically identified by a horseshoe-shaped mound of fire-cracked stones and charred material accumulated over repeated use. They are found in their thousands across Ireland, almost always in low-lying, waterlogged ground close to a stream or spring, and this example fits that pattern closely, sitting roughly fifteen metres east of the Rampart Stream.

The site is heavily overgrown, and the burnt material is visible only where it has been exposed in the face of a natural scarp to the east of the stream, a small earthen cliff cut by erosion or drainage that has opened a cross-section through the accumulated debris. That exposure, though modest, is what confirms the site's presence and character. The boggy conditions that made such locations practical for prehistoric communities, who would have used the nearby water source in combination with heated stones to bring large quantities of liquid to the boil, have also helped preserve the organic and burnt material beneath the vegetation.
