 Bede repeats the story in his "Ecclesiastical History", written c. 731.The otherwise unspecified 'City of the Legion' is arguably Caerleon, Welsh "Caerllion", the 'Fortress of the Legion', and the only candidate with a long and continuous military presence that lay within a Romanised region of Britain, with nearby towns and a Roman "civitas".Other candidates are Chester and Carlisle, though both were located far from the Romanised area of Britain and had a transitory, more military-oriented history.
