That, in its own quiet way, is the point. Beneath the grass lies a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically identified by a horseshoe or crescent-shaped mound of fire-cracked stones. These sites were in use from the Bronze Age onwards; the working principle involved heating stones in a fire and dropping them into a water-filled trough to bring it to boiling point, leaving behind a tell-tale spread of shattered, heat-fractured rock. The one at Coolroe More once broke the surface clearly enough to be recorded as a semicircular mound on the Ordnance Survey six-inch map of 1937. By the time fieldworkers came to document it in detail, no visible trace remained.

What makes this site quietly interesting is not its isolation but its company. Within a radius of roughly 300 metres, two further fulachtaí fia have been recorded: one approximately 280 metres to the north-north-east, another around 230 metres to the north-east. This kind of clustering is not unusual in the Irish landscape; fulachtaí fia are among the most common archaeological monument types in the country, and they frequently appear in loose groupings near water sources, low-lying ground, or ancient routeways. Whether the three sites at Coolroe More were used simultaneously, by the same community, or represent activity returning to a familiar area across generations, is something the surface record cannot answer.
