The Round Table at Camalot was rumoured to have seated between 25 and 150 people. According to most of the Legends associated with the Round Table it was used to host a series of banquets at Camelot, taking place each year at Pentecost. The Round Table was first mentioned in about 1155, By Wace in his "Roman de Brut,".

After Lancelot and Arthur's wife Queen Guinevere betrayed their king by becoming lovers Sir Lancelot and the knights gathered at the Round Table to hold a meeting of the Council of the Order of the Knights of the Round Table. Some accounts suggest that Lancelot voluntarily quits the order and leaves for France. Those knights who argued in his favour at the meeting also went to France with him. This struck a severe blow to King Arthur's court and subsequently the Kingdom was never the same again.

The remaining members of the order later met again at the Round Table for the last time when King Arthur became fatally ill. This is where an image of the Holy Grail first appears above the Round Table which prompts the quest to find the Grail in the desperate hope of saving the king.
