Thousands of people came from across Britain to help build Stonehenge, experts investigating the origins of the monument have said.
They said people travelled from as far afield as the Scottish Highlands.
Researchers from University College London said their findings overturned what was thought about the origins of the monument.
Until now it had been thought that Stonehenge was built as an astronomical calendar or observatory.
The latest findings, which came after a decade of research, suggested it was the act of building the monument rather than its purpose that was key.
