The rise is only about a metre above the surrounding land, and most visitors would likely walk straight past it without a second glance. Yet that slight elevation, and the roughly circular shape it traces across the boggy field, is what remains of a structure once significant enough to be carefully mapped by Ordnance Survey teams in both 1841 to 1842 and again in 1914 to 1915.

Circular enclosures of this kind are a familiar feature of the Irish landscape, typically interpreted as the remains of a ringfort or rath, a type of enclosed farmstead that was common from the early medieval period onwards. They were usually defined by an earthen bank, sometimes with an outer ditch, and served as a defended homestead for a farming family. Here, whatever defined the original boundary has largely dissolved back into the ground. What survives is a sub-circular raised area, its southern edge now interrupted by a fieldbank running east to west, which has cut across the older form and obscured part of its outline. The waterlogged conditions of the surrounding land may actually account for the enclosure's survival in any form at all; wet, marginal ground tends to be left undisturbed by later agricultural activity, which is perhaps why the low mound persisted through the centuries while so many similar sites elsewhere were ploughed flat.
