It measures roughly 24 metres long and 12 metres wide, and to an untrained eye it could pass for nothing more than a slight unevenness in the ground. What it almost certainly represents, however, is a fulacht fia, one of the most common yet least understood monument types in the Irish archaeological landscape.

Fulachtaí fia, found in their thousands across Ireland, are the remains of ancient cooking or heating sites, typically consisting of a mound of fire-cracked stone accumulated over repeated use. The general process involved heating stones in a fire and dropping them into a water-filled trough to bring the water rapidly to a boil, shattering the stones in the process and leaving behind the characteristic spread of dark, burnt material that survives today. Most examples date to the Bronze Age, roughly 1500 to 500 BC, though some sites were used across longer periods. The Currabwee example sits on a gentle south-facing slope, and a spring lies close by. That proximity to water is no coincidence; a reliable natural water source was essentially a prerequisite for a working fulacht fia, and sites are almost invariably found near streams, springs, or boggy ground.
