The mound, measuring roughly 107 metres on its longest axis and nearly 90 metres across, is not especially dramatic to look at: a gentle rise of earth and stone, its edges defined by an irregular scarp and fragmentary bank. What makes it curious is the gap between what it appears to be and what it may once have been.

The site sits on low-lying ground in Ballynacross, divided across two townlands by a field boundary that cuts through its interior. A second boundary further subdivides the larger northeastern portion, giving the whole thing the somewhat awkward geometry of a place that has been quietly absorbed into the working landscape over centuries. In 1978, the landowner described it as an old graveyard, a memory that had apparently persisted in the area long enough to be worth recording. That local tradition, combined with the site's considerable size and oval form, points towards the possibility that it originated as an early ecclesiastical enclosure. Such enclosures, common in early medieval Ireland, typically surrounded a church and its associated burial ground within a roughly circular or oval boundary, often later mistaken for a ringfort or rath. About 220 metres to the southeast lies a holy well, a feature that frequently occurs in proximity to early Christian sites in Ireland, where sacred landscape elements tended to cluster rather than stand alone.
