This groundbreaking book explores the evidence embedded in medieval monasteries, churches and castles, from Mont Saint-Michel and the Leaning Tower of Pisa to Durham Cathedral and the Basilica of Santiago de Compostela. Tracing the origins of key design innovations from this pre-Gothic period--acknowledged as the essential foundation of all future European construction styles--Diana Darke sheds startling new light on the masons, carpenters and sculptors behind these masterpieces.

At a time when Christendom lacked such expertise, Muslim craftsmen had advanced understanding of geometry and complex ornamentation. They dominated high-end construction in Islamic Spain, Sicily and North Africa, spreading knowledge and techniques across Western Europe. Challenging Euro-centric assumptions, Darke uncovers the profound influence of the Islamic world in "Christian" Europe, and argues that "Romanesque" architecture, a nineteenth-century art historians" fiction, should be recognized for what it truly is: Islamesque.
