Its outline, roughly 90 metres across from north to south, only becomes legible from the air, where aerial photography has revealed a semi-circular ditch tracing the western, southern, and northern arc of the monument. The eastern side has been obscured by a modern road cutting through on a north-west to south-east alignment, removing whatever cropmark trace might once have appeared there.

The enclosure sits at a striking convergence of boundaries. Its eastern edge coincides with the townland boundary between Granardkill and Ballynagall, and the site also touches the boundary with Ballygilchrist, suggesting it may have influenced how this landscape was divided long after the monument itself fell out of use. A field fence built after 1700 cuts across the southern portion, adding another layer of later activity over the earlier earthwork. What makes the broader landscape particularly arresting is the density of ringforts in the immediate vicinity. A ringfort, typically a circular earthen or stone enclosure used as a farmstead in early medieval Ireland, appears at four points around the enclosure, one roughly 375 metres to the north-north-east, one 200 metres to the east, another 200 metres to the south, and a fourth around 260 metres to the west. Whether the large enclosure predates these or was contemporary with them is not clear, but their clustering around it gives the impression of a site that once held some significance in the local geography.

The monument is not marked or interpreted on the ground, and its presence is only really legible through aerial photography, including earlier Ordnance Survey Ireland images on which the cropmark was also recorded. A cropmark appears when buried features such as ditches or banks affect the growth of surface vegetation above them, producing subtle colour or height differences visible from altitude. At Granardkill, without that aerial perspective, the enclosure remains effectively anonymous in the grass.
