The site is gone, drained out of existence, and leaves no visible trace on the surface. That absence is itself a kind of record, a reminder of how much of prehistoric Ireland has quietly vanished, not through dramatic upheaval but through the ordinary business of agricultural improvement.

A fulacht fia is a type of ancient cooking site found in great numbers across Ireland, typically consisting of a horseshoe-shaped mound of fire-cracked stones beside a trough, usually timber-lined, into which water was poured and heated by dropping in stones from a fire. They date most commonly to the Bronze Age, though examples from other periods are known. The one at Ballinvrinsig was recorded by Walsh in 1985, who noted it had already been destroyed by drainage works. Once a field is drained and the ground reshaped to suit modern farming, the shallow, waterlogged conditions that both characterised these sites and helped preserve them are simply gone.
