An elongated oval stone enclosure, measuring 36m x 16m and aligned NW/SE, is sited on the north-east summit of Cadair Idris. Unusually the north-west part of the enclosure takes in a steep slope, while the exposed position of the enclosure makes it unlikely that it performed a mundane agricultural function like a sheepfold. The walls enclose a small cairn or outcropping rock suggesting a prehistoric date would not be unlikely. Recorded during RCAHMW aerial reconnaissance on 2nd October 2015.
