A glen where lived the magical Owl of Cwm Cawlwyd.
Arthur visited the owl to consult his wisdom during his quest to find the missing warrior Mabon in Culhwch and Olwen. The Owl of Cwm Cawlwyd directed Arthur to the Eagle of Gwernabwy. A Welsh Triad lists the Owl as one of the “three Elders of the World”.
