There is nothing to see at the surface, no mound, no hollow, no scatter of stones, yet the site qualifies as one of Ireland's most common and most quietly fascinating prehistoric monument types, known from thousands of locations across the country.

A fulacht fia, sometimes called a burnt mound, is essentially an outdoor cooking place. The typical arrangement involved heating stones in a fire and dropping them into a water-filled trough to bring it to the boil, a method that left behind a distinctive crescent-shaped mound of fire-cracked and blackened stone. At Ardrahan, a quantity of such burnt stones came to light during drainage works, which is how a good number of these sites are found, churned up by agricultural improvement rather than deliberate excavation. Local information confirmed the find, and it was recorded as part of the North Kerry Archaeological Survey, published in 1995 by C. Toal. No surface trace has been visible since.
