Summary: The work of 1971–3 has produced a variety of important results. The Roman defences and defended area sequences set out in the first report have been confirmed with modifications of detail. New evidence has been found for the nature and extent of the Roman city outside the defended area: there are now the first hints of Roman planning in the St. Catherine Street—Hare Lane area and in Lower Northgate Street there was at least one monumental building and a street-side colonnade. Sub-Roman occupation has been recorded at 13–17 Berkeley Street. New evidence has been obtained for the possible first phase of Gloucester castle and the development of the medieval defences. The excavated evidence for the medieval occupation at 13–17 Berkeley Street has been combined with, and partly reinterpreted in the light of documentary evidence. At 82–4 Northgate Street the standing remains of a sixteenth-century and later building were recorded and its site excavated and related to documentary evidence. In the light of new discoveries, accounts are also given of St. Bartholemew's Hospital, the river Severn, and its two main medieval bridges within the city bounds.
