The enclosure measures roughly twenty-five metres across and is defined by an earth and stone bank with an external height of about one and a half metres, dropping to just thirty centimetres on the interior side, and an outer fosse, a ditch dug to reinforce the enclosure's boundary, some three metres wide and nearly a metre deep. What makes it genuinely puzzling is the absence of any visible entrance feature. Enclosures of this kind, when ancient, typically preserve at least a causeway or a gap in the bank where people and animals once passed through. Here, there is nothing of the sort.

The working theory is that the enclosure may not be ancient at all, but rather a deliberate landscape feature associated with the plantation that surrounds it, probably laid out during the nineteenth century when landowners across Ireland were reshaping their estates with ornamental plantings, boundary works, and occasionally decorative earthworks. If that interpretation is correct, it would explain the unusually clean bank profile and the missing entrance: a feature designed to be seen or to organise the land visually, rather than to contain livestock or enclose a settlement, might never have needed one. The classification remains cautious, recorded simply as a possible landscape feature, which is a polite way of saying that no one is entirely certain what it is or why it was built.
