It measures approximately 38 metres east to west and 32 metres north to south, its boundary defined by an earthen bank and an external fosse, the fosse being a shallow defensive ditch dug around the outside of the bank. Only the northern arc of this arrangement remains legible, running from the north-west through to the north-east; the rest has been worn down or disturbed over time.

The damage is not purely the work of centuries. Quarrying has cut into the bank at the north-east and south-west, suggesting the site was at some point treated as a convenient source of material rather than a feature worth preserving. This is not unusual for enclosures of this type, which are common across Ireland and generally understood to date from the early medieval period, roughly the sixth to the twelfth centuries. They served many purposes, from the ringfort-style enclosure of a farmstead and its associated buildings to the demarcation of ecclesiastical or ceremonial ground. Without excavation it is difficult to say with any certainty which category this one falls into. A house recorded nearby, around 110 metres to the east, sits in proximity to the site but its relationship to it, whether contemporary, later, or simply coincidental, remains unclear.
