It is about 38 metres in diameter and raised on a platform standing somewhere between three and six metres high, which gives it a commanding presence despite being entirely consumed by the surrounding woodland. Along the eastern side runs a berm, a narrow flat ledge sitting between the raised platform and any outer boundary, and towards the north-east this berm appears to transition into a fosse, essentially a defensive ditch cut into the ground. Together, these features suggest something deliberately constructed and designed to control movement and define a bounded space.

The site belongs to a broad class of enclosed earthworks found throughout Ireland, whose precise functions varied considerably, from ringforts used as defended farmsteads in the early medieval period to later manorial or ceremonial enclosures. What makes this particular example quietly intriguing is the detail at its south-western edge, where a ramp appears to mark a formal point of access, the kind of feature that implies deliberate planning rather than simple agriculture. The Glen of the Downs itself is a glacially carved valley, and the choice to site an enclosure on the steep flank overlooking it rather than on more level ground below says something about whoever built it, though precisely who, and when, remains unrecorded.

The site is described as very overgrown, which makes close inspection a matter of patience and careful footing rather than a straightforward walk. The ramp at the south-west offers the most likely way in, and the shift from berm to fosse at the north-east is probably the most legible feature for anyone willing to pick through the undergrowth to find it.
