A stopping place in Pembroke mentioned in the Mabinogion of the seven survivors of the expedition to Ireland mounted by Bendigeid Vran to avenge the ill-treatment of Branwen at the hand of the Irish King Matholwch.

They remained in a great hall at Gwales for a total of eighty years, the severed and uncorrupted head of Bendigeid Vran keeping them company, until one member of the seven opened a door facing towards Cornwall. At once, all seven were filled with memories of what had passed and left to continue their journey to London, where they fulfilled the last orders of Bendigeid Vran and buried his head, face towards France, under the White Mount.
