On the windy summit of Mynydd Maendy south of Tonyrefail, is a burial chamber reputed to be the grave of the chieftain later known as King Arthur.
The advance of the Anglo-Saxons across Britain was halted for a generation by this brave leader whose crowning victory was at Caerfaddon (Bath) in A.D 513.
Many legends were attached to this nameless hero, and the King Arthur tradition was born, first of all in Wales, and then in the literature of nearly every country in Europe.
