One of the locations frequently named as Arthurís palace, or residence, or capital, particularly in continental literature. It is almost certainly a variation of Carlisle in Cumberland, although Cardueilís location is often given as Wales or Brittany.

It was the home of Do (Sir Girfletís father, whom Malory confusingly calls 'Cardol'), Arthurís niece Lore, and Arthurís knights Asgares the Sad and Briamont.

Under Arthur, Meliant administered the city. In Arthour and Merlin, it is the site of the first battle between Arthur and the rebelling kings - a skirmish which the Vulgate Merlin places at Caerleon.

In the prior Livre díArtus, King Urien torches the city during the rebellion. Arthur rebuilds it, only to have the Saxon King Arrant burn the city again.

According to the romance of Yder, it was the birthplace of Sir Yder and was outside Arthurís kingdom.
