Stonehenge is the nation's most famous monument. For centuries, its age and purpose have been subject to speculation, excavation and fantasy. But over the last six years, a huge new team of archaeologists have been digging not just the monument but the entire prehistoric landscape that focuses on Stonehenge, to reveal the truth about this near-mythical place and crack its secrets.

Time Team's cameras have been with the dig through those six summers. During their excavations the team discovered the biggest Neolithic settlement in Northern Europe, which suggests they have found the place where the people who built Stonehenge were based. But the digs also reveal that Stonehenge was just part of a vast ritualistic landscape where ancient peoples celebrated life and death in great man-made structures.

The archaeologists believe that the landscape was turned into a huge and complex special ceremonial route for the remains of the departed as they pass into the afterworld. But these theories are only proved in their last summer of digging in 2008, as the team start to dig in the stone circle itself. The results surpass their wildest dreams and this pivotal excavation finally enables the team to reveal not only when Stonehenge was built and how it was built but, perhaps most importantly, why it was built.
