The Stonehenge Hidden Landscapes Project revealed some amazing new features to this prehistoric monument. Researchers used six different techniques to scan the whole site at different depths below the surface including a magnetometer, a ground-penetrating radar (GPR) and a 3D laser scanner.  This enabled researchers to virtually see through the ground and explore what civilization might have looked like thousands of years ago. The team's new three-dimensional map covers an area of 12 sq km or 1,250 football fields and suggests that the monument was accompanied by 17 neighbouring shrines.
