Camulodunum, Doleceste, Kaercolun
A city in southeast England, in Essex. The Romans called it Kaercolun or Camulodunum. The latter name has been suggested as the source of Camelot. This association coming from the similarity of the Roman name, though this could also be sais about any place-name that has 'Cam' in it, whether Roman or British.
