Dozens of prehistoric, Roman and medieval sites are discovered by lockdown archaeologists

Citizen scientists searching aerial images while on coronavirus lockdown have uncovered dozens of previously-hidden Roman, prehistoric and medieval sites. Archaeological digs are currently on hold due to the pandemic but researchers have found roads, burial mounds and settlements - all while working from home. Researchers from the University of Exeter asked teams of volunteers to search through LiDAR images and aerial surveys to hunt for signs of ancient sites. Volunteer amateur archaeologists cross-referenced these topographical images of the Tamar Valley that highlight hidden features with historic maps of the area. Lead researchers Dr Chris Smart said they were'redrawing the archeological map of the South West' and getting a better idea of how areas developed over millennia.
