Much of the Mabinogion saga is based in the Ardudwy region of North Wales. It was from the ‘Castle Rock’ or ‘Rock of Harlech’ (where Harlech Castle now stands) that the Welsh King Bendigeidfran first saw the Irish longboats of Matholwch loom into view with their shields turned upside down as a sign of peace.
Specific Location: Harlech
The Groes Las settlement between Harlech and Llanfair was a domestic agricultural homestead in prehistory. It consists of the remains of a hut circle with walls approximately 3.0 metres thick and up to 1.2 metres high.
