Heavily overgrown and leaving no surface trace, it survives now more as a cartographic memory than as anything a person could point to or stand beside.

A fulacht fia is a type of prehistoric cooking site, found in great numbers across Ireland, typically consisting of a horseshoe-shaped mound of burnt and fire-cracked stone beside a trough, into which heated stones were dropped to boil water. They are among the most common archaeological monument types in the country, yet their precise purposes remain debated; cooking is the leading theory, but brewing, bathing, and textile processing have all been proposed. The Clontead Beg example was recorded as a mound on the Ordnance Survey six-inch map of 1938, which means that at least at that point in the twentieth century there was still something visible above ground. Since then, the marshy ground and encroaching vegetation have done their work, and whatever low earthwork once marked the spot has been absorbed back into the landscape.
