Many castles claim to be Arthur's Camelot, but the most likely one is Tintagel Castle, Cornwall (though there is no evidence for this). In Camelot sat the famous Round Table, where Arthur, his queen Guinevere, Merlin, Morgan le Fay, Sir Lancelot, Sir Gawain, Percival and many other valiant knights sat. Arthur and his knights went on many quests including The Quest For The Holy Grail, The Green Knight, The Black Knight and more.
