England

“More than half a million aerial images of historical sites in England have been used for a new mapping tool.

Photographs and 3D laser scans have been taken over the past 30 years to uncover “hidden archaeological landscapes”, Historic England said.

Sites include 6,000-year-old long barrows, Roman camps such as those on Hadrian’s Wall and 20th Century areas linked to the world wars.

The map covers more than half of the country.”
