At the end of the Middle Ages, castles began to lose their military function, but not their psychological impact as a symbol of authority. Gun powder and cannons supported armies of mercenary troops, and the garrison forts built to house them adopted the crenellated walls of private aristocratic castles. By the sixteenth century, professional soldiers lived in barracks, a few officers and the governor had finer quarters, and kings and nobles merely directed the operations from distant palaces where battlements had become purely symbolic decoration. The Battle of Crecy between France and England in 1346 is traditionally considered to be the first use of cannons on the battlefield. At first the noise and smoke created by the explosion terrified horses and men, and wreaked more havoc than the projectiles. Early cannons could be more dangerous for the gunners than for the enemy, but military engineers rapidly developed the weapons’ power and accuracy. A castle’s high walls and towers made easy targets for gunners whose power and accuracy reduced once formidable medieval buildings to rubble. Mining became more successful because the attackers could put explosives under the walls.

A motte and bailey castle consists of a man-made hill (the motte) supporting a tower and a walled yard (the bailey). (...) Early castle builders looked for a natural hill on which to erect a timber tower, but since a hill might not be available where fortifications were needed, they raised a flat-topped, conical earthen mound by digging a circular trench or ditch the desired diameter and heaping up the dirt in the center.

Castles continued to be the focus of economic activity as the center of an agricultural domain. Wealth continued to be measured in land and its produce. The only access the lord had to his wealth was to move from one estate to another consuming products from the harvests. Housing and feeding a household including retainers and servants required vasts amount of food and space for food preparation.
