Handbook to Roman Legionary Fortresses by M. C. Bishop
Mike Bishop here provides a handy reference guide to every securely identified Roman legionary fortress. An introductory section details the main building types, the development of fortress plans and construction, their defences and infrastructure. The main body of the book, however, comprises the gazetteer, detailing the fortresses' location, dimensions, construction history, garrisoning, and bibliography, the majority illustrated with a site plan.
