A substantial integrated and interpretative report of the archaeological evidence for the occupation and defense of this impressive multivallate hillfort between the late Bronze Age and the Saxon and early medieval periods. Chapters examine the construction sequence of the castle, largely based on its ceramic sequence, and finds recovered from the `massacre levels' resulting from the Roman violent conquest of the fort during the 1st century AD. Production resources and residues, largely associated with metal and stone working, agricultural features and implements as well as dress accessories and domestic items are also examined in some detail.
