A rath, or ringfort, once occupied this ground: one of the circular earthwork enclosures, typically dating from the early medieval period, that were used as defended farmsteads across Ireland. Thousands survive in various states of preservation, but this one does not. It has been completely levelled, and nothing visible remains at the surface.

What makes the Glouria site quietly interesting is the paper trail it left behind before it vanished. It appears on the Ordnance Survey maps of 1841 to 1842, marked as a circular enclosure, and it was still recorded on the 1914 revision. By the time the Geological Survey of Ireland took aerial photographs in 1974, the feature was visible from the air, its outline readable in the landscape even as ground-level traces were presumably already fading. At some point after that, the levelling was completed, and the enclosure disappeared from the land entirely, surviving only in the cartographic and photographic record. C. Toal documented it in the North Kerry Archaeological Survey, published in 1995, as site no. 271, though by then there was already nothing left to see in the field.
