The great walled castles of the medieval world continue to fascinate the modern world. Today, the remains of medieval forts and walls throughout Europe are popular tourist sites. Unlike many other books on castles, The Medieval Fortress is unique in its comprehensive treatment of these architectural wonders from a military perspective. The Medieval Fortress includes an analysis of the origins and evolution of castles and other walled defenses, a detailed description of their major components, and the reasons for their eventual decline. The authors, acclaimed fortification experts J.E. and H.W. Kaufmann, explain how the military strategies and weapons used in the Middle Ages led to many modifications of these structures. All of the representative types of castles and fortifications are discussed, from the British Isles, Ireland, France, Germany, Moorish Spain, Italy, as far east as Poland and Russia, as well as Muslim and Crusader castles in the Middle East. Over 200 photographs and 300 extraordinarily detailed technical drawings, plans, and sketches by Robert M. Jurga accompany and enrich the main text.
