The structure measures roughly ten metres across in both directions, with an interior height of around 0.9 metres and an exterior height of 0.8 metres, making it a modest but deliberate feature of the terrain. An entrance gap of about 2.5 metres faces roughly east-south-east, suggesting an intentional orientation rather than simple accident of construction or erosion.

Enclosures of this kind are a common but still poorly understood feature of the Irish countryside. The term covers a broad range of circular or near-circular earthworks, some associated with early medieval settlement, others possibly used for livestock management or ritual purposes. What makes this particular example quietly interesting is its setting alongside relict field systems in the same area, traces of an organised agricultural or pastoral landscape that has long since fallen out of use. Together, the enclosure and these ghost field boundaries suggest a period when this mountain plateau supported something more purposeful than it does today. The bank is now partially obscured by gorse, the interior softened by grass and ferns, and the whole thing is more legible from the air than from the ground.
