It measures roughly 19 metres along its longer axis and half a metre in height, with an uneven surface that hints at the repeated activity that built it up over time. At its south-western end sits a shallow, waterlogged depression, about four metres long and three metres wide, with a stream running to the west of the site. These are the characteristic remains of a fulacht fia.

A fulacht fia is a type of ancient cooking or heating site found widely across Ireland, most commonly dating to the Bronze Age, roughly 2000 to 500 BC. The basic principle involved heating stones in a fire, dropping them into a water-filled trough to bring the water to boiling point, and then using that water to cook meat or, according to some interpretations, for bathing, brewing, or industrial processes such as working leather. The mound of burnt and shattered stone that accumulates beside the trough is the defining feature, the discarded fire-cracked material building up into exactly the kind of low, horseshoe-shaped or oval mound visible at Belrose. The waterlogged depression here likely represents the site of the original trough, kept wet by the proximity of the stream to the west, which would have been the water source for the whole operation. These sites are extraordinarily common across the Irish landscape, yet individually they tend to sit quietly in fields, unannounced and easy to overlook.
