The Towns of Roman Britain [PDF ebook] 

This edition of the text has been rewritten and re-illustrated to take account of the extensive new excavations and interpretations that have taken place since the book was first published twenty years ago. The central section of the text covers the origin, development, public and private buildings, fortifications, character and demise of each of the twenty-one major towns of the province: the provincial capital of London; the coloniae – Colchester, Lincoln, Gloucester and York; the first civitas capitals – Canterbury, Verulamium and Chelmsford; from client kingdoms to civitas – Caister-by-Norwich, Chichester, Silchester and Winchester; Flavian expansion – Cirencester, Dorchester, Exeter, Leicester and Wroxeter; and Hadrianic stimulation – Caerwent, Carmarthen, Brough-on-Humber and Aldborough. The introductory chapters address the general questions of definition and urbanization, while the concluding chapter examines the reasons for the decay and final demise.
