In October 2009 the archaeologist Professor Mark Pearson in charge of the Stonehenge Riverside Project announced the Blue Stonehenge find.
The so-called Blue Stonehenge was another circle of 25 Bluestones about 10m (33ft) in diameter constructed on the west bank of the River Avon and surrounded by a henge - a ditch with an external bank. The size of the holes in which they stood indicated that they would have been bluestones.
Evidence shows that the henge surrounding it was built around 2400 BC but the bluestones were put up about 500 years before that. These stones are believed to originate from the Preseli mountains 150 miles away and it is possible that they were later incorporated into the central original bluestone circle of Stonehenge.
This exciting discovery formed part of the ongoing Stonehenge Riverside Project led by Professor Pearson. The project involved the universities of Sheffield, Bristol, Manchester and Bournemouth and was funded by National Geographic Society, Google, The Societies of Antiquaries of London and the Society of Northern Antiquaries.
This Blue stonehenge find greatly contributes to the continuing and expanding knowlege of the area around Stonehenge. It is becoming more apparent that this was a very large complex ceremonial area bounded by the River Avon, Amesbury and Boscombe Down airfield of which the Stonehenge we see today comprises a small part.
By using the modern equipment and techniques now at the disposal of the modern archaeologist is our knowledge and understanding of the whole complex being slowly and painstakingly uncovered with the prospect of more exciting discoveries in the future.
