Durrington Walls Excavation, Stonehenge, Wiltshire
A Later Neolithic henge enclosure of roughly oval shape measuring around 490 metres by 470 metres and defined by a ditch with a bank outside. This excavation took place in 1967 before the A345 was re-routed through the enclosure. The excavation confirmed the later Neolithic date of the earthwork and a strong association with Grooved Ware pottery. It provided evidence for much earlier activity on the site, dating back to the 4th millennium BC. There was also evidence of some later, Early Bronze Age (Beaker) and Iron Age activity.
