In recent year excavation of two Durham City sites, namely Leazes Bowl and Claypath, have uncovered large scale, comprehensive assemblages of both medieval and post-medieval pottery and glass. Up-to-date archaeological recovery techniques make these important sites for the study of both domestic and trade wares. The huge quantity of glass from the Claypath excavations is also of great importance. Comprising over one hundred bottles, it represents the largest assemblage of post-medieval domestic glass in the country and is of central importance to future archaeological research into this field.
The museum also holds the archives and finds relating to the Durham City Survey, which provide an excellent resource and reference point for future research into both Durham in particular and urbanism in general.
