The enclosure measures approximately 130 metres north to south and 90 metres east to west, making it a substantial feature in the landscape, yet its purpose remains unresolved. What survives on the ground is not a single coherent boundary but nine small rectangular enclosures, each defined by low grass-covered banks or scarps, some up to 37 metres by 35 metres. These subdivisions are what the original D-shaped outline, as recorded on the 1839 edition of the Ordnance Survey six-inch map, actually contained.

By the time the Ordnance Survey cartographers set to work in the 1830s, the enclosure was already partly obscured. A north-to-south field bank had cut across its western edge, truncating the original shape and suggesting that the land had been reorganised for agricultural use long before anyone thought to record it. The River Bann runs roughly 250 metres to the west, and the site's position on a sloping hillside above the river valley is consistent with a range of early settlement types, though nothing in the physical evidence pins it to a particular period or function. Embanked enclosures of this scale in Ireland can be associated with early medieval activity, but without excavation such associations remain speculative. What the 1839 map captures, in effect, is a palimpsest: a large earlier boundary containing a later system of small enclosures, all of it slowly flattening into the surrounding field pattern.
