This collection comprises site data from an archaeological watching brief undertaken in July 2014 by Oxford Archaeology during the installation of a new damp proof membrane along the west range of the Radcliffe Quadrangle at University College, Oxford. The watching brief revealed the construction cut for the east wall of the cellar of the west range of the quad, which was constructed between 1675 and 1676. Additionally, a series of imported garden soils and landscaping deposits were revealed.
