It is a fulacht fia, one of the most common yet persistently mysterious monument types in the Irish landscape. These sites, found in their thousands across the country, are broadly understood to be Bronze Age cooking places, typically consisting of a trough dug into the ground and a surrounding mound of fire-cracked stone and charcoal left over from repeatedly heating rocks and dropping them into water. The mechanics are well established; the social context, rather less so.

This particular example sits some 90 metres north-east of a stream, in ground that is prone to flooding, which is entirely characteristic of the type. Fulachtaí fia are almost always found close to water, and their placement in wet or waterlogged areas was almost certainly deliberate, making it easier to keep the trough filled. The mound here measures roughly 10 metres east-north-east to west-south-west, and just under 7 metres in the other direction, with a trough 1.64 metres wide and 1.24 metres deep, opening towards the south-south-east. What makes this site quietly notable is its company: a second fulacht fia lies approximately 130 metres to the south-west, suggesting that this stretch of the Caherweelder landscape saw repeated or sustained use during prehistory, rather than being the location of a single, isolated episode of activity.
