In this talk, Professor David Nash will present the latest research by his team on where the sarsen megaliths at Stonehenge originally came from. He will explain the development of the geochemical fingerprinting technique used to match sarsen stones to source areas, which has its roots in the analysis of Middle Stone Age tools in the Kalahari Desert of Botswana.

The talk will show how the team identified West Woods, near Marlborough, as the likely source of the giant sarsens, and consider what this finding means for the construction of Stonehenge.
