Within the interior of this circular earthwork in Kilcarrooraun, County Galway, there is both a souterrain and a standing stone, two features that rarely share the same enclosed space. The combination suggests a site used across different periods, or for purposes that were never entirely straightforward.

The rath itself, a type of ringfort defined by an earthen bank rather than stone walling, measures forty metres in diameter. Its bank is around four metres wide and survives to a maximum height of just over half a metre, which places it in fair rather than spectacular condition. It sits on a north-west-facing slope in rough grazing land, the kind of landscape that has kept many such monuments from being ploughed away. A drain has been cut around the western side of the monument at some point, which may reflect later agricultural activity encroaching on, or at least brushing up against, the older structure. Souterrains are underground stone-lined passages or chambers, typically associated with early medieval settlement and thought to have served for storage or as places of refuge. Their presence within a rath is relatively common. A standing stone sharing that same enclosed space is less so, and its original purpose here is not recorded.
