Sitting in undulating grassland in Cooladooaun, this well-preserved rath has a standing stone 135 metres to its south-east and another ringfort just 120 metres to its north, suggesting that what looks like open countryside was once a meaningfully organised landscape, with monuments clustered in a way that implies shared purpose or at least shared occupation.

The rath itself is subcircular in plan, measuring roughly 35 metres east to west and 30 metres north to south. It is defined by an earthen bank and an external fosse, which is simply a ditch dug around the outside of the enclosure, the upcast material from which typically formed the bank itself. Raths of this kind were the most common settlement type in early medieval Ireland, serving as enclosed farmsteads for families of moderate status, though they also accumulated later folklore associating them with the supernatural. A number of small gaps break the enclosing bank at Cooladooaun, though these appear to be modern rather than original features, meaning the overall structure has come through remarkably intact. The relationship between this rath, the standing stone to the south-east, and the neighbouring ringfort to the north has not been fully explained, but the proximity of three monuments of different types and possibly different periods points to a corner of Galway that was returned to, built upon, and read as significant across a very long stretch of time.
