The trees have effectively sealed it off, making it one of those archaeological features that exists more confidently on paper and in the air than on the ground. Enclosures of this kind are among the most common earthwork monuments in Ireland, typically interpreted as the remains of ringforts, the enclosed farmsteads of early medieval landholders, though some examples are considerably older. What makes this one quietly odd is its double identity: surveyed on the ground in the nineteenth century, it reappears centuries later only as a shadow caught by an aerial camera.

The first formal record of the site appears on the 1840 edition of the Ordnance Survey six-inch map, where it was partially marked as an enclosure associated with a triangulation station, the kind of fixed reference point surveyors used to calculate distances and elevations across the landscape. The fact that the OS cartographers noted any enclosure at all, even partially, suggests the earthwork was visible and recognisable at that date. By 1974, aerial photography confirmed what ground-level access could not: a circular enclosure was still legible from above, captured in a GSI survey flight. Its position on elevated ground, with good views in all directions, is the sort of siting that recurs again and again with early Irish settlement sites, where visibility and defensibility went hand in hand.
