Augusta (c. AD 350–80)

London’s later Roman defences were enhanced by a series of towers, or bastions, likely to have been built in association with military campaigns in Britain in the 360s. The revived walled city housed important institutions of Roman government, several of which were later described in the Notitia Dignitatum, and was renamed Augusta. This chapter reviews the archaeological evidence for the fourth century city set within its historical context. It also summarizes the uncertain evidence of London’s first Christian communities, and considers the extent to which new institutional arrangements gave rise to new forms of public architecture.
