Craig-y-Dinas
A mount in North Wales, near Snowdon, which featured in a story told by Iolo Morgannwg. Iolo Morgannwg was the bardic name of Edward Williams (1747-1826). He collected a great deal of early Welsh lore, but as a bard he is not regarded as a reliable source.
In Iolo's story a Welshman, led by a magician, found Arthur and warriors sleeping in a cave there, guarding treasure. A similar tale, narrated by J. Rhys, has a Monmouthshire farmer as its protagonist. For tales of similar nature set in England, see Alderley Edge and Thompson.
A cave called Ogo'r Dinas near the Llandebie was also thought to house the sleeping Arthur.
Craig, is a Welsh word and means a high rock or craig, sometimes also applied to a steep, woody eminence. In Ireland it takes the form of carraig or carrick; in England it is found in Crick, Cricklade, and so on.
