Stone foundations, interpreted as part of a milecastle on Hadrian's Wall, were uncovered in 1985 during the conversion into the Newcastle Arts Centre of 67–75 Westgate Road (National Grid reference NZ 2452 6401). The initial discovery was made and pursued, and almost all the subsequent excavation carried out, by David Fry, the resident potter at the Centre, with constant encouragement from Mike Tilley, the director. The recording on site, and responsibility for eventual publication, was undertaken by members of the Tyne and Wear Archaeology Unit, who are grateful to Charles Daniels and Brian Dobson for their helpful advice during the preparation of this report, and to John Dore, John Casey and Jacqui Huntley for their specialist reports.
