The enclosure at Ballincurry sits in pastureland looking out over partly drained marshland to the north, a subcircular earthwork that once described a near-complete ring but now survives as something more fragmentary and easier to overlook than its considerable dimensions might suggest.

An enclosure of this type, defined by an earthen bank and an external fosse (a dug ditch running around the outside of the bank), is a form that appears widely across the Irish landscape and spans a broad range of periods, from the early medieval ringfort tradition to earlier prehistoric uses. Here, the bank survives to a maximum height of 1.5 metres, and the fosse measures between three and four metres wide, features that are reasonably well preserved along the southern, western, and northern arcs of the monument. The eastern half tells a different story: a townland boundary running north to south cuts straight through the middle of the enclosure, and on that eastern side the ground has been partly levelled and planted with trees. A field boundary also cuts through the southeastern quadrant. Within the surviving earthwork, there are traces of a possible entrance roughly four metres wide at the southeast, and hints of an internal division in the southwestern quadrant, details that suggest a more complex interior arrangement than the present condition of the site makes easy to read.
