This work concentrates on the rich architectural heritage of both early and late medieval Ireland, preceded by an introduction on the groundwork laid by the Celts. The legacy of this period - manuscripts and metalwork, churches and great stone crosses, family tower houses and feudal castles have all been photographed by O'Brien and documented by Harbison for this book. Maps, charts and timelines afford the reader greater understanding of the complex world of medieval Ireland.
