A fulacht fia is a type of prehistoric cooking or processing site, typically consisting of a mound of fire-cracked stones beside a trough, used by heating the stones and dropping them into water. This one, by local account, was flattened during land reclamation and covered over with topsoil, leaving no visible trace above ground.

The site was recorded by Bowman in 1934, noted in a survey entry that relied on local information rather than direct inspection. That gap between record and reality is itself telling. Reclamation of marginal and wetland ground, which accelerated throughout the nineteenth and twentieth centuries as farmers improved drainage and extended productive pasture, quietly erased a great many low-lying archaeological features across Ireland. Fulachtaí fia are particularly vulnerable to this kind of loss; they tend to occur in damp, low-lying spots, precisely the ground most attractive to drainage schemes. The Nohaval example appears to have been one casualty among many, known only because someone thought to ask locally before the memory faded entirely.
