Oxford Archaeology was commissioned by TMD Building Consultancy on behalf of Somerville College to undertake archaeological watching brief for the groundworks associated with the renovation of the kitchen and dining hall at Somerville College, Oxford. Archaeological mitigation took place as an intermittent watching brief depending on the principal contractor's work programme between October and December 2020. The watching brief has shown that whilst untruncated natural gravel survives within the site no significant archaeological deposits or features were observed. The 19th-century garden soils and construction deposits associated with the kitchen and dining hall recorded during the archaeological watching brief are considered to be of low significance.
