Between 3rd and 14th July 2006 an archaeological excavation was carried out by the Cambridge Archaeological Unit (CAU) prior to the development of additional student accommodation at St. Edmund’s College, Cambridge. The present excavations formed the fourth stage of archaeological investigations carried out by the CAU prior to the building works, following two evaluation phases in 1996 and in 2005 (Dickens 1996; Ten Harkel 2005), the latter of which ran partially through the present site, and an open area excavation immediately to the west of the present site, completed in April 2005 (Mackay 2006). The excavations were carried out in accordance with a specification of works, and were monitored by the Development Control Office of the Cambridgeshire County Council.
