Camlann is Arthur's final battlefield on Salisbury Plain where he received his mortal wound by Mordred. The name "Camlamm" is probably derived from the British word Camboglanna, which means "crooked bank" (of a river), or Cambolanda, "crooked enclosure."
Camlann is mentioned in a few of the triads, particularily in the one headed "Three Unrestrained Ravages," which describes the events leading up the final battle between Arthur and Mordred. Also mentioned in "Three Futile Battles," Camlann is describes as a bloody and tragic clash that was the result of a feud with Mordred.
One of the Roman forts on Hadrian's wall was called Camboglanna, and is pictured here, but discontinuities prevent an exact location of the Arthurian Camlann.
