LIDAR may reveal camp of Hadrian's Wall builders

The study of a series of old LIDAR (light detection and ranging) aerial photos has led to the discovery of what may be a camp of the men who constructed Hadrian's Wall. The find could change the way historians view civilian life in Roman Britain.

From surface investigations, archaeologists believed that they saw only military installments around the wall, but the LIDAR studies show something else: a landscape of thousands of undefended farms. "You can only have a landscape like that when people are so used to peace that they take it for granted. And that utterly changes the story of how we see the Romans," said surveyor Humphrey Welfare.
