At some point during land reclamation work in scrubland, a low mound of burnt material came to light, only to be further levelled by the very works that uncovered it. What had survived for perhaps three or four thousand years was recorded, briefly, and then erased.

The feature in question was a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, particularly in low-lying or marshy ground. The typical form is a horseshoe-shaped mound of fire-cracked stones, accumulated over repeated use of a nearby water trough into which heated stones were dropped to boil water. The Ballynagree example, known only through local information gathered before the mound was gone, conforms to the most common fate of such sites in agricultural landscapes: discovered incidentally, noted, and obliterated. It leaves no visible surface trace.
