The village of Aldborough in North Yorkshire was once the site of one of the northernmost urban centres of the Roman Empire, known then as Isurium Brigantum. Founded in the 2nd century, perhaps under the Emperor Hadrian, the Roman walled town acted as a focus of the Brigantes, the largest tribe in Roman Britain. Using archaeological evidence, this guidebook attempts to describe what life must have been like for the Brigantes under Roman rule. The mosaic pavements uncovered at the site, together with jewellery and numerous other finds now housed in the site museum, suggest that Isurium must have been a thriving, prosperous town. The book includes reconstruction drawings and photographs of the sites and museum exhibits.
