The Stonehenge Riverside Project was a major Arts and Humanities Research Council-funded archaeological research study of the development of the Stonehenge landscape in Neolithic and Bronze Age Britain. In particular, the project examined the relationship between the Stones and surrounding monuments and features including the River Avon, Durrington Walls, the Cursus, the Avenue, Woodhenge, burial mounds, and nearby standing stones. The project involved a substantial amount of fieldwork and ran from 2003 to 2009. It found that Stonehenge was built 500 years earlier than previously thought and was built to unify the peoples of Britain. It also found a new stone circle, Bluestonehenge.
