It appears on the first Ordnance Survey six-inch map, surveyed in 1839 to 1840, as a clearly defined circular enclosure, the kind of low ringwork, typically a raised bank enclosing a domestic or ceremonial space, that dots the Irish countryside in varying states of survival. By the time the same map was revised in 1945 to 1946, it had already softened into a roughly oval outline marked only with a dashed line, trees growing within what remained of its interior. Satellite imagery taken between 2005 and 2019 shows nothing at all.

What makes its disappearance more than a routine loss of earthwork is its proximity to a near-identical enclosure just thirty metres to the west. That neighbouring site yielded a number of human burials, which suggests that this corner of Loughboy once held real significance, whether as a settled place, a burial landscape, or both. The two enclosures were roughly the same size and sat within easy sight of one another, and it is tempting to read them as related, though the record is silent on the nature of any connection. The burials at the western enclosure place people here with some certainty; the eastern one, now levelled into the grass, leaves fewer answers behind.
