(Roman). Londinium was the provincial capital of Roman Britain from c. ad 60 onwards. Roman remains have been located at the confluence of the rivers Thames and Fleet. London's status appears to have been enhanced after Colchester (the original provincial capital of Roman Britain) was destroyed during the Boudiccan revolt of ad 60. A tombstone of the new procurator, Gaius Julius Classicianus, dating to the aftermath of the revolt, suggests that London had now become the seat of administration.
