No mound rises from the soil, no stones break the surface; the site announces nothing of itself to anyone passing through.

A fulacht fia is a type of ancient outdoor cooking place found in great numbers across Ireland, typically consisting of a horseshoe-shaped mound of fire-cracked stones built up beside a water source, with a trough nearby that would have been filled with water and heated by dropping in stones from a fire. They are associated broadly with the Bronze Age, though some examples span a wider range of periods. The Farnanes example was recorded as a mound on the Ordnance Survey six-inch map of 1943, which means it was still detectable at ground level within living memory. At some point between that survey and more recent inspection, whatever surface presence it once had disappeared entirely, absorbed into the boggy ground or disturbed by the slow work of drainage, cultivation, or time. What the 1943 map recorded as a mound is now, in practical terms, invisible.
