There is almost nothing left to see. The bank of earth and stone that once defined the perimeter has been reduced to the point where a significant section of it, from the north-west around through north to the north-east, has left no visible trace at all. A drain cuts across the monument in that same arc, likely responsible for much of the loss in that quarter. Gaps on the south and west sides appear to be modern interventions rather than original features.

The site was recorded by Neary in 1914, catalogued as number 83 in a list that placed it among the many such enclosures scattered across County Galway. The rath measures roughly 33 metres east to west and 32 metres north to south, making it nearly circular, which was a common form. Raths of this size would typically have enclosed a single family's domestic buildings, with the earthen bank providing a boundary as much social as defensive. That so little of this one remains above ground is not unusual; centuries of agricultural activity, drainage schemes, and general land improvement have reduced many such monuments across Ireland to faint suggestions of their former shape.

What survives at Carrowkeelanahglass is less a monument to look at than a lesson in how thoroughly a landscape can absorb its own past. The slight rise that distinguishes the site from the surrounding level grassland is, by now, perhaps the most legible thing about it.
