The ground is rough and uneven, the terrain climbs awkwardly through undulating upland pasture, and nothing at ground level gives any indication that a roughly circular earthwork, somewhere between sixty and seventy metres in diameter, was once detectable here at all.

The enclosure came to light not through excavation or fieldwork but through a single aerial photograph taken in 1973, catalogued under the reference GSI S.500/499. Aerial photography has long been one of the more revealing tools in Irish archaeology, capable of picking out crop marks, soil discolouration, and the faint geometries of buried or overgrown features that are entirely invisible from the ground. In this case, the photograph showed a roughly circular form, with a curving field boundary making up its eastern quadrant. That boundary has since been removed, and with it went the last visible trace of the enclosure above ground. Circular enclosures of this kind are common across Ireland, often associated with early medieval settlement, but the location here is notably unusual. Upland terrain this rough and marginal would not typically be considered a likely site for one, which makes the question of its original purpose all the harder to answer.
