Colchester
Before Roman times, Colchester was Camulodunon. This is a Celtic name that came from Camulos. Camulos was the Celtic god of war. The Romans called Colchester Camulodunum (written "CAMVLODVNVM") and made it the capital of Roman Britain. Colchester was attacked and burnt by Boudicca in 61 AD.  The Romans moved their capital of Britannia to Londinium (now London), but Camulodunum remained an important city until the fifth century, when the Saxons conquered the region.
