Frances Lynch (“A Guide To Ancient and Historic Wales – Gwynedd” 1995 HMSO) has this to say about this fabulously enigmatic monument:
The circle is probably the remains of a Bronze Age burial monument rather than a ceremonial circle, but so little remains that certainty is impossible. Four stones less than 1m high still stand on the arc of a circle 4m in diameter, and the two stones outside the arc may have been moved when the monument was incorporated into a field-wall (now largely removed). The large block of quartz on the north-east is of uncertain date.
