A roughly circular arrangement of stones adjacent to the cairn on the summit of Mynydd Pen Cyrn. Approximately 2m in diameter it is built from boulders of various grades and appears to be 2 to 3 boulders in height with the lower course earth-fast. It is possible that this is the feature recorded by Kay, 1952, as an avenue .
