Archaeologists have unveiled the most detailed map ever produced of the earth beneath Stonehenge and its surrounds.
They combined different instruments to scan the area to a depth of three metres, with unprecedented resolution.
Researchers used six different techniques to scan the whole site at different depths below the surface.
Amongst their instruments was a magnetometer, a ground-penetrating radar (GPR) and a 3D laser scanner
Early results suggest that the iconic monument did not stand alone, but was accompanied by 17 neighbouring shrines.
Future, detailed analysis of this vast collection of data will produce a brand new account of how Stonehenge’s landscape evolved over time.
Among the surprises yielded by the research are traces of up to 60 huge stones or pillars which formed part of the 1.5km-wide “super henge” previously identified at nearby Durrington Walls.
“For the past four years we have been looking at this amazing monument to try and see what was around it,” Prof Vincent Gaffney, from the University of Birmingham, said at the British Science Festival this week.
