This ancient fortification was only officially recognised in 1987 during aerial surveys, though it had likely been slowly disappearing into the landscape for centuries. The site consists of a large subcircular enclosure, roughly 165 metres from northeast to southwest and about 130 metres the other way, making it one of the more sizeable hillforts in County Galway.

The defensive boundaries of this ancient settlement tell a story of both natural advantage and human engineering. On the northwestern, northern, and northeastern sides, the builders cleverly utilised a natural rock scarp that rises up to two metres high, whilst elsewhere they constructed stone walls that have since collapsed and become overgrown. The best-preserved section of walling runs from the south-southeast through to the southwest, where you can still see remnants about six metres wide and nearly a metre high on the exterior face.

Today, the interior of the hillfort presents a palimpsest of different periods of human activity. Five modern stone walls cut across the ancient enclosure, most radiating out from a later ringfort built in the northern section. The hill’s summit in the northwest also features a cairn, whilst the southwest quadrant contains the foundations of what appears to be a rectangular house measuring about 12.5 by 5 metres. These later additions show how this prominent hilltop continued to attract settlement long after the original Iron Age inhabitants had departed, creating a complex archaeological site that spans millennia of Irish history.
