In Arthurian Legends, Corbenic is the site of the Grail Castle; the mythic place where the Holy Grail is kept safe by the Grail Kings.

The origin of the name of the Castle of Corbenic is uncertain.

However, the name may come from Corbin-Vicus.

If the "ic" part of the word comes from the Romans, then the ending of the name is almost certainly derived from the Latin for town or military settlement.

The Welsh name of the hill is after Bran the Blessed or Bran Fendigaid. The word bran means crow or raven. The word bran translates into the French of the Romance writers by the word Corben.

Castell Dinas Bran, a possible site of the Grail Castle, is sometimes known as "Crow Castle".

This etymology is far from certain. There is no textual basis to support these assumptions. What is more, there is no reason why the word crow was linked to the Grail Castle of King Arthur mythology.

However, in Welsh myth, Bran Fendigaid or Bran the Blessed, has interesting parallels to King Arthur. Just like King Arthur's knights, Bran went on a long journey to find a magical Vessel of Plenty. This was a Celtic Cauldron of Rebirth. Also, like the Grail-King, he was wounded by a spear and his land became a wasteland until he was healed.

Bran may have been the first of the Grail-Kings of Arthurian legend. However, the first Grail King was named Brons. He was the son-in-law of St. Joseph of Arimathea.
