The Avenue is a grand scale earthwork monument sweeping 3km (1.8 miles) from the River Avon to the north eastern entrance of Stonehenge. It dates from between 2600 and 1700BC and is contemporary to the construction of the stone circle.

Theories about its purpose vary. The final approach to Stonehenge is aligned on the midsummer sunrise. Was it a ceremonial approach to Stonehenge?

Other researchers think that it was the route used to transport the blue stones of Stonehenge from the river to their final destination.
