What survives is roughly half of what was once a subcircular enclosure, approximately sixty metres across on its north-south axis, now bisected so cleanly by a later field boundary that the eastern portion has vanished almost entirely. To the west-southwest, faint traces of a fosse, the external ditch that would originally have accompanied the bank, are still just legible in the ground. To the north, the circuit has been clipped further, leaving a straight scarp where a curved edge once stood.

Enclosures of this kind are among the most common yet least understood monuments in the Irish landscape. The term covers a wide range of structures built across many centuries, from early medieval ringforts used as farmsteads to earlier enclosures whose purpose remains unclear. Without excavation, it is rarely possible to say with confidence what a given example was for or when it was built. At Ballincurry, the surviving arc of bank, running from the southwest around to the northwest, is enough to suggest the original form, but the monument has been too thoroughly altered by agricultural activity over the years for much more to be read from the surface alone. The intrusion of a field boundary cutting the site in two is a common fate for earthworks in farmed landscapes, where the logic of land division routinely overrides the preservation of older features.
