Castrum to Castle: Classical to Medieval Fortifications in the Lands of the Western Roman Empire

For over a thousand years, from the time of the Roman Empire to the classic period of castle-building in the twelfth and thirteenth centuries, fortified sites played a key role in European warfare. This highly illustrated history gives a fascinating insight into their design and development and into the centuries of violence and conflict they were part of.

The study traces the evolution of fortifications starting with those of the Romans and their successors. Included are the defenses erected to resist Islamic invasions and Viking raids and the castles that were built during outbreaks of warfare. As the authors demonstrate, castles and other fortifications were essential factors in military calculations and campaigns - they were of direct strategic and tactical importance wherever there was an attempt to take or hold territory.

The factors that influenced their location, layout and construction are analyzed, as is the way in which they were adapted to meet the challenges of new tactics and weapons.
