Time Team S07E05 hadrians.wall,.birdoswald

Tony Robinson and the Team travel to the Roman fort of Birdoswald in Cumbria to carry out the first ever excavation of a Roman cemetery near the wall.

But during the dig - which includes a spectacular recreation of a funeral pyre - they also discover the remains of a Roman town that ceased to exist after the year 200.

Could it have been one of the largest Roman towns in northern Britain? And why did it die?
