The Catuvellauni tribe’s capital was Vervlamivm. The coins of Tasciovanus were the first to appear with the mint name VER [ulamion], circa 20 BC. The town became a munucipium, whose inhabitants were granted Roman rights in law around 50 AD. The capital was located at St. Albans, Hertfordshire and their territory stretched to Cambridgeshire, Bedfordshire, Buckinghamshire and Oxfordshire east of Charwell.
