These were typically enclosed farmsteads of the early medieval period, defined by one or more earthen banks and, usually, a fosse, the external ditch that provided the material for the bank. What survives at Carrownacreevy is modest but still legible: a raised circular area roughly 25 metres in diameter, partially enclosed by a low, degraded bank of earth and stone, ranging between two and three and a half metres wide and rising only about half a metre above the surrounding ground.

The site tells a quiet story of incremental loss. Moving around the perimeter, the damage changes character depending on the direction. Along the south to south-west arc, the original bank was absorbed into a field boundary at some point and subsequently levelled, its fabric essentially cannibalised by later agricultural organisation of the land. On the opposite side, running from the south-west around through the west to the north-north-west, the situation is more abrupt: the construction of a north-north-east to south-south-west roadway has cut through both the perimeter and part of the interior, removing a significant portion of what the monument once contained. No fosse is present, or at least none that has survived, and the original entrance, which in many ringforts appears as a gap or causeway through the bank, can no longer be identified. What remains is the northern arc, from north-north-west through north to south-south-east, where the bank, though degraded, still traces the curve of the original enclosure.
