The monument's original stones were erected in about 2300 BC, it has been discovered - 300 years later than had previously been thought.
Analysis has indicated that the original circle of bluestones was transported to the site from the Preseli hills, 150 miles away in South Wales - an extraordinary feat.
The finding came in an ambitious project, involving the first dig inside the historic stone circle for 44 years.
