Stretching the breadth of northern England, Hadrian's Wall is a majestic reminder of the ambition and might of the Roman Empire's conquest in Britain.
For decades, archaeologists struggled to date the indigenous communities around the wall because the site yielded very few artefacts. The only way of dating these Roman and pre-Roman Iron Age settlements was to excavate what little there was. Since the 1970s, when serious excavation began, experts believed the local population living in the shadow of the wall had actually flourished under the Roman invaders. But the new evidence suggests the Roman legions actually cleared a 10-mile stretch in front of the wall by force.
