A circular enclosure roughly 25 metres in diameter was recorded on Ordnance Survey maps in both 1838 and 1929, but by the time anyone looked closely at the ground itself, there was nothing left to see. Levelled completely, with no visible surface traces remaining, it survives only as a ring on old cartographic records and a brief entry in a local survey.

What makes its absence interesting is its location. The enclosure sat about 200 metres north-north-west of an early ecclesiastical enclosure and church, a proximity that is unlikely to be coincidental. In early medieval Ireland, circular enclosures of this kind were commonly associated with settlement, ritual, or the organisation of land around a religious site. The pattern of a satellite enclosure positioned close to a church complex is well attested across the country, suggesting this feature was probably part of a wider landscape that once surrounded the Kilkeeran ecclesiastical site. The 1838 Ordnance Survey mapping gives a reasonable terminus ante quem for its visible existence, and the fact that it was still legible on the 1929 revision suggests the levelling happened sometime in the twentieth century, most likely through agricultural improvement of the pasture in which it stood.
