The Roman city of Verulamium

Shortly after the second Roman invasion of Britain, the Iron Age settlement of Verlamion acquired a new identity as Verulamium. The destruction of the town by Boudicca afforded the opportunity to implement Roman town planning principles, and Verulamium became one of the largest Roman cities in Britain (at least by area). Unlike many other Roman towns and cities, Verulamium's sub-surface remains were largely undisturbed until the 19th century, allowing modern archaeologists to map the layout more comprehensively than elsewhere. Work continues on surveying the site.
