Publisher's Synopsis
Fortifications on the scale of these walls are unique in that they are (apart from individual castles) the only known military measure with long-term aims. The military aims sometimes proved of extremely long-term value, the most extreme example being the erection of the Great Wall of China. The aim of this volume is to find out the common denominator (if any) behind the creation of such fortifications, their effectiveness and their influence on a long and short-term basis. Contents include: The Limes * Hadrians Wall and the Antonine Wall * The "Danewerk" * The Frontera: Spanish Defences against the Moors * The Great Wall of China * The French Eastern Border * The Berlin Wall * The Jerusalem Wall
