From February 2003 to March 2005, Oxford Archaeology (OA) carried out a programme of archaeological work in King's Lynn comprising evaluation, strip and map, excavation and watching brief integrated with the redevelopment of the Vancouver Centre and the construction of the Clough Lane multi-storey car park. Despite extensive modern construction, archaeological features, structures and deposits of medieval date (12th-15th centuries) were recorded along the existing frontages of Broad Street and New Conduit Street. Archaeological deposits, building foundations and yard surfaces of late medieval/post-medieval date (15th and 16th-18th centuries) were recorded.
