It is roughly rectangular, measuring around forty metres north to south and thirty metres east to west, and it is defined by a modest bank rising about half a metre above the surrounding ground, with an external fosse, or ditch, cut to a depth of roughly 1.2 metres. That combination of bank and ditch is the basic grammar of early Irish enclosed settlement, a form used from the prehistoric period through the early medieval era to delineate farmsteads, ceremonial spaces, or places of shelter and storage. What makes this particular example quietly curious is its staying power on the historical record: it appears on Ordnance Survey six-inch maps from 1842, 1903, and 1940, each time in roughly the same form, a smudge of earthwork that cartographers kept dutifully marking across a century of surveys.

The enclosure was described by Walsh in 1985 as an irregular example of the type, which suggests its corners and edges do not conform to the tidy geometry implied by the word rectangular. Irregularity in these structures is not unusual; earthworks built by hand over soft or uneven ground shift and soften over generations, and banks that were once sharp-edged become rounded humps. The fosse at 1.2 metres deep is a reasonable cut, substantial enough to have defined a boundary with some purpose behind it, though whether that purpose was defensive, agricultural, or ritual is not something the physical evidence alone can settle.

The site is currently inaccessible due to overgrowth, which means a visitor approaching the pasture in Ballynora would find the enclosure concealed rather than displayed. That is not an unusual condition for earthworks of this kind in County Cork, where scrub and bramble often reclaim the margins of fields around surviving features. The enclosure is there, confirmed by successive maps and ground survey, persisting in its south-facing slope, largely unexcavated and uninterpreted beyond its outline and its dimensions.
