1. Long hut on S side of an old track leading south-east of Craig Cefn-coch to the Afon Ddu. It lies on ground sloping gently to the SE but is not built up to form a platform. It is 37ft long NW - SE and 10ft wide. The walls, 3 ft thick, are of large boulders and in places reach a height of 2ft 6ins. The hut is earlier than the track, which swerves to avoid it. It is ruined and reeds are growing on it.
