Today, it survives as something considerably quieter: a barely perceptible rise across pasture, bisected by a field boundary and a north-flowing stream, its outline legible more to the trained eye than the casual passer-by. What makes its disappearance worth noting is not simply the effects of time and agriculture, but the particular way its memory was preserved, and then lost again, in layers.

The enclosure measured roughly 82 metres east to west and 60 metres north to south, straddling a natural gully on the slope. Enclosures of this kind, broadly circular or oval earthworks defined by a raised bank and an outer fosse (a shallow ditch running around the perimeter), are a recurring feature of the Irish countryside, associated variously with settlement, agricultural, or ritual use across a long span of prehistory and the early medieval period. At Ballymacallen, the 1842 six-inch Ordnance Survey map depicted it clearly with hachures, the cartographic shorthand for an earthwork bank, and traces of its southern arc were still visible within the field boundary system as late as the 1935 survey. Local knowledge filled in a detail the maps could not: the southern arc had survived not as an earthen bank but as a line of blackthorn bushes, the kind of boundary planting that often quietly inherits the line of older features. Those bushes were cleared during field fence works around 1976, removing the last legible surface trace of the enclosure's southern side.

What remains now is slight: a low rise running west to east across the field, and a barely perceptible trace of the external fosse. The townland boundary, running north to south, bisects the site, as does the stream, so the enclosure has been partitioned not once but twice by the administrative and hydrological geography of the landscape around it.
