CHERISH Project aerial reconnaissance for the Royal Commission on 15th July 2019 identified indistinct cropmarks south of Treginnis-uchaf of a circular, ditched cropmark enclosure built on the west flanks of a minor stream valley. The enclosure measures some 60m across, and may well represent the remains of a prehistoric defended enclosure.
