 During the Iron Age a large hill fort now known as Vespasian's Camp was built alongside the Avenue and overlooking the River Avon.The fort could easily have catered for up to 1000 people, and was probably surrounded by smaller settlements and farming communities.Roman remains are poorly documented at Amesbury, but excavations have revealed Roman structures in the Stonehenge landscape, and Wessex Archaeology have discovered a large Roman graveyard in the area of the Amesbury Archer burial.
