St Andrews academics unveil secrets of Stonehenge in new documentary St Andrews academics are featured in a new documentary unveiling the secrets of Stonehenge. Stonehenge: The Lost Circle Revealed will include Fife researchers who have completed a ground-breaking study into the famous landmark in Wiltshire. St Andrews University scientists were part of a team who revealed that bluestones used in the construction of Stonehenge around 5,000 years ago were taken from the ancient Welsh stone circle at Waun Mawn. Dr Tim Kinnaird, of the School of Earth and Environmental Sciences at St Andrews University, said: “It is the hidden information preserved in the soils that provides the chronology for the construction, then the dismantlement of the Waun Mawn stone circle, which appears to have intriguingly occurred just before similar stones were erected at Stonehenge.
