Bwlch y Saethau
(The Pass of the Arrows), Snowdon
The site of a fierce battle took place between Arthur and his enemies. His knights retreated to the precipice of Lliwedd, taking shelter in a cave called Ogof Llanciau Eryri (Cave of the Lads of Snowdonia). The entrance to the cave closed and his knights went to sleep, where they wait for Arthur to return and lead them once more.
