The inner structure, a subrectangular drystone enclosure measuring roughly 21.7 metres east to west and 11.8 metres north to south, occupies the eastern half of a much larger enclosure. Drystone construction, meaning walls built without mortar by carefully fitting stones together, is found across the Irish landscape in many periods, and the technique alone cannot date a site. What gives this place its particular character is the layering, one boundary folded inside another, each suggesting a different phase or purpose.

A field wall running roughly east-north-east to west-south-west may overlie, or simply follow, the northern limit of the inner enclosure, which raises a question that archaeology often leaves open: did a later agricultural boundary happen to align with an older one, or did farmers working the land centuries on simply recognise a useful line and follow it? At the western side of the inner enclosure, a gap marked by a large boulder may indicate an original entrance. References to the site appear in published works by Holt in 1912 and McCaffrey in 1952, suggesting it has attracted scholarly attention across more than a century, though the broader questions of date and function remain unresolved.
