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.
