The enclosure is modest in scale, around 36 or 37 metres across in either direction, and its edges survive today mainly as scarps, low earthen drops of between 0.2 and 0.4 metres, the kind of subtle undulation that most walkers would step over without a second thought. Only at the north-west does a later field bank reinforce the boundary, and it is this same bank that truncates, or cuts across, what was once a more complete D-shaped form.

The D-shaped enclosure is a fairly common type in the Irish landscape, generally understood as a settlement or farming boundary from the early medieval period, though the category covers a wide range of uses and dates. What gives this particular example some additional interest is its landscape context. It sits on a gentle north-west-facing slope with the River Shannon lying roughly 200 metres to the east, and a rath, a circular earthen ringfort enclosure, sits approximately 150 metres to the south. The juxtaposition of two distinct enclosure types in such close proximity suggests this was an actively used and organised stretch of ground at some point in the past. The 1914 edition of the Ordnance Survey six-inch map recorded the site's D-shaped outline, which means the truncation by the field bank had already occurred by that date, though the original form was still legible enough to be mapped.
