Oxford Archaeology North

Oxford Archaeology (OA, trading name of Oxford Archaeology Limited) is one of the largest and longest-established independent archaeology and heritage practices in Europe, operating from three permanent offices in Oxford, Lancaster and Cambridge, and working across the UK. OA is a Registered Organisation with the Chartered Institute for Archaeologists (CIfA), and carries out commercial archaeological fieldwork in advance of development, as well as a range of other heritage related services. Oxford Archaeology primarily operates in the UK, but has also carried out contracts around the world, including Sudan, Qatar, Central Asia, China and the Caribbean. Numbers of employees vary owing to the project-based nature of the work, but in 2014 OA employed over 220 people.

The registered head office is in Osney Mead, Oxford, southern England; this address is also the base for OA South. Other offices are OA North in Lancaster, northern England, OA East in Bar Hill, Cambridgeshire, eastern England. For a short time, OA had offices in Mauguio (OA Méditerranée), southern France and Caen (OA Grand Ouest), northern France.

In the late 1960s, the recently created Oxford City and County Museum led the archaeological response to a development boom in Oxfordshire. However, the museum lacked the resources to tackle the rescue crisis alone. The museum's answer was to form independent excavation committees in response to specific development threats, starting in Oxford in 1967. These committees were registered charities with public benefit at the heart of their purpose. They employed short-term contract staff, supplemented by volunteer diggers.
