It is a fulacht fia, a type of prehistoric cooking site found in large numbers across Ireland, typically consisting of a mound of fire-cracked stone and charcoal accumulated beside a trough or water source. The basic method involved heating stones in a fire, then dropping them into a water-filled pit to bring it to a boil. What was actually cooked or prepared there remains a matter of debate among archaeologists, with meat, fish, and even textile dyeing among the proposed uses.

This particular example measures twelve metres north to south and twelve metres east to west, rising to a modest height of around forty-five centimetres, with an opening roughly four metres by two metres facing the river. Fulachta fiadh are most commonly dated to the Bronze Age, broadly spanning from around 2000 to 500 BC, though some sites fall outside that range. The location here is quietly suggestive: the Paps of Dana, two breast-shaped hills in County Kerry, take their name from Danu, a figure associated with the Tuatha Dé Danann in Irish mythology, lending the surrounding landscape a deeper layer of cultural resonance even if the mound itself is simply a practical remnant of daily prehistoric life.
