The enclosure measures roughly 27 metres north to south and 24 metres east to west, its interior rising gently toward the centre, the north-east corner now overtaken by vegetation. It is not a dramatic feature. Standing at the edge of it, you might easily mistake it for a field boundary or a fold in the land. That quiet ambiguity is precisely what makes it interesting.

By the time the Ordnance Survey produced its six-inch map of the area in 1842, the interior of the enclosure had been planted with coniferous trees, suggesting it was considered a feature worth marking, perhaps even ornamenting, within the broader landscape of Kildinan demesne. A demesne, in Irish usage, refers to the managed estate lands surrounding a house of some status, so the enclosure existed within a cultivated, organised setting rather than open countryside. Whether it was already ancient by the time those trees went in, or whether the planting itself shaped what we see today, is not clear. Earthen enclosures of this kind are a recurring feature of the Irish countryside, sometimes associated with early medieval settlement or land use, sometimes with much later agricultural or ornamental purposes, and the surviving form alone rarely settles the question. The gap in the bank to the north-north-west, only about a metre wide, could represent an original entrance or a later breach; the earthwork does not say.

Today the enclosure sits in pasture, the trees of the 1842 map long gone, the bank low and unassuming. The north-east corner remains overgrown, softening whatever geometry the original builders intended.
