The area-excavation towards the centre of the fort has shown that well-defined traces of occupation exist, ranging from the Roman period to the early nineteenth century. The nature of the Roman occupation, though still uncertain in many aspects, is becoming much clearer and can now be divided into phases tentatively linked to a broad historical framework. Early in the fifth century settlement of Germanic type appeared, with which was associated a gilded bronze disc of apparently sub-Roman form. Then followed more regular Saxon occupation, beginning in the late fifth or early sixth century and probably continuing to the eighth or ninth century. The late Saxon period provides a very detailed picture of a hall with its ancillary buildings, land boundaries, and rubbish-tipping area, all of considerable potential significance on more than a local scale. The later periods are more sporadically represented, but interesting correlations can be made between the archaeological evidence and contemporary documentary and graphic accounts.

To understand the internal landscape of the fort more clearly it is evident that much more of the central area will have to be fully excavated and this will occupy most of the effort throughout the next five seasons' work. At the same time it is planned to continue with the investigations of the Priory and the Castle, and to devote some time to the outstanding problem of the defences.
