Dan Jones explores Roman roads Dere Street, the northern-most Roman road in Britain running from York to Scotland, and Stanegate, a key east-west route that runs alongside the great defensive barrier of Hadrian's Wall. His journey reveals the story of Roman military and its colonial ambitions in Britain.

Dan Jones travels the historic Roman road of Ermin Way, which links the two Roman towns of Calleva Atrebatum and Glevum, now known as Silchester and Gloucester. Not to be confused with Ermine Street, which runs from London to York, Ermin Way is arguably Britain's most industrial Roman road.
