Europe, Conventional 

This profusely illustrated and thoroughly researched book describes in detail the diverse methods used to attack and defend castles during the Middle Ages. In a groundbreaking study — the first to shed light on the purpose, construction techniques, and effectiveness of medieval fortifications, noted nineteenth-century architect and writer Eugene-Emmanuel Viollet-le-Duc discusses such architectural elements as dungeons, keeps, battlements, and drawbridges. In addition to describing a vast number of European structures — among them fortifications at Carcassonne, Paris, Avignon, Vincennes, Lubeck, Milan, and Nuremberg — he examines the use of artillery and trenches, as well as such weapons as battering rams, mines, and the long-bow. A concise, scholarly reference for architectural historians, this absorbing history will appeal as well to medievalists, military buffs, and anyone interested in the evolution and development of the castle. - from Amzon
