Britain holds tens of thousands of prehistoric sites. Collectively, they illustrate how ways of life developed over long periods of time: how the hunter-gatherer communities of the Palaeolithic and Mesolithic gave way to the first herder-farmers from northern France; how their descendants built great earth circles from the chalk soils of Wessex, erecting stone-lined tombs and, centuries on, the colossal enclosures of megaliths.
The story of how these migrants displaced the builders of Stonehenge and Avebury is traced across the British landscape to this day, along with the outlines of the field enclosures, farmsteads and hillforts
