What was once a fulacht fia, a type of prehistoric cooking or industrial site typically identified by a horseshoe-shaped mound of fire-cracked stone and charcoal left behind by repeated heating of water in a pit or trough, has been levelled. The mound of burnt material, the very thing that would have marked this place out on the landscape for thousands of years, was flattened during tree planting operations. The forestry that replaced it is now, by all accounts, inaccessible.

Fulachtaí fia are among the most common prehistoric monument types in Ireland, found in the hundreds across Cork alone, usually in low-lying or marshy ground near water. They date broadly to the Bronze Age, though some examples have produced dates ranging from the Neolithic through to the early medieval period. The one at Knocknagappul follows a pattern that will be familiar to anyone who has looked into the fate of Irish field monuments: it survived millennia in the ground, only to meet its end in the twentieth century during land improvement or commercial forestry work. What the local information preserves is essentially an epitaph, a note that something was here, and that the physical evidence of it is gone.
