Image of Craig yr Aderyn (Crag-top enclosure) (Ancient Village / Settlement / Misc. Earthwork) by thesweetcheat

Set below the cairn on the highest part of the hill is what appears to be a further rampart of some kind. It seemed to me to be all of a piece with the stone walls encircling the hillfort to the northwest and the crag-top enclosure in between the two summits.
