The Development of the Irish Town [PDF ebook] 

Originally published in 1977, and now with an updated new Preface, this volume covers the question of Irish urban origins in the pre-Norman period, the character and development of the medieval towns, the changing forms and functions of towns and cities in the early modern period. It also examines the substantial changes in size and form effected by population growth and town planning in the eighteenth and nineteenth centuries. Ireland’s urban history is unique and particularly interesting for the way it contrasts with developments in the urban history of western Europe. Unlike most west European regions, it was not colonised by the Romans.
