An excavation in 2010-12 on the site of the former Ministry of Defence (MoD) Headquarters in Durrington, Wiltshire, revealed evidence spanning the post-glacial to the post-medieval periods. It lies immediately north-east of the Stonehenge part of the Stonehenge, Avebury and Associated Sites World Heritage Site. The significant discoveries made during the excavation include a relatively deeply buried Late Glacial Allerød soil, and a zone of Late Neolithic activity centred on a number of natural solution hollows, posthole alignments and pit groups. The Late Iron Age defences, probably constructed in the immediate pre-Conquest period and decommissioned soon after, influenced the layout of early Romano-British fields and settlement activity. This report describes the site, and places it in its local context. Reports on the finds, dating and environmental remains are also presented.
