In the 1980s work began on construction of the vast underground Castle Mall shopping centre in Norwich. The associated archaeological excavation was one of the largest of its kind in northern Europe, designed to investigate not only the castle bailey but also pre-Conquest settlement and, for the post-Conquest period, areas of the surrounding medieval city. Documentary evidence that supplements the substantial data presented in the monograph (parts I and II) forms Part IV (EAA occasional paper 23), published separately because of the scale of the data and because it forms a rounded resource in its own right. It provides additional data on medieval and later properties around the entire circuit of the Castle Fee, permitting ease of access to information that might otherwise have been obscured within the complexity of the integrated monograph.
