Camelot, also called Camaloth or Camaaloth, is a legendary city, of Arthurian legend.
Camelot was the seat of the court of the mythical King Arthur, ruler of "Brittany", i.e. present-day England, Wales and mainland Britain, south of Hadrian's Wall. Arthur and Queen Guinevere held their court there where the Round Table was established.
No one has been able to locate this legendary place, but it is probably a buried city somewhere in England, whose pre-Celtic origins date back to prehistoric times.
