An examination of Roman London that surveys building materials, tools, and construction methods before moving through streets, walls, gates, bridges, cemeteries, tombs, and larger monuments. The work describes masonry, brick and tile usage, concrete techniques, and decorative arts such as sculpture, mosaics, wall painting, and marble linings, while noting measurements and craft practice. Chapters consider inscriptions and lettering, the organization of trades, and the emergence of early Christian sites, concluding with reflections on the city’s origins and the provincial character of Roman architectural expression in Britain.
