Barrow Clump, on the east side of the Avon valley, lies in the centre of the Salisbury Plain Military Training Area. It is the site of a large, partly extant Early Bronze Age burial mound which incorporates an earlier Beaker funerary monument, seals a Neolithic land surface, and was the focus of an Anglo-Saxon cemetery, most of the 70 graves dating to the 6th century AD. Excavations in 2003-4 were carried out largely in response to the damage being caused to this and other prehistoric monuments by badgers. The subsequent work in 2012-14 was made possible by the participation of Operation Nightingale (Exercise Beowulf), an innovative military initiative to involve injured service personnel in archaeology to aid their recovery.
