A Neolithic causewayed camp in Devon, England, with radiocarbon dates showing occupation from 4200-3900 BC. It has given its name to the plain pottery (also called Windmill Hill pottery) of the earliest Neolithic in southern England, round-bottomed bowls frequently with lug handles. An Iron Age hillfort was later built and postholes of a circular Neolithic house have been found beneath the Iron Age gate. The Neolithic deposit included greenstone and flint axes and charred spelt wheat - by far the earliest occurrence of this type of wheat in Britain.
