The castle was far more than a walled and turreted fortress; it was an instrument of social control and the symbol of power, authority, and wealth. - Marilyn Stokstad

The siege warfare of the Middle Ages consisted of blockading the castle in hopes of destroying it or taking it over for one’s own use. In peacetime castles controlled the surrounding land, but when hostilities broke out they provided passive resistance and served as a base of operations.

Were castles really as rough and rugged as their owners? The answer seems to be, “not necessarily.” Castles were indeed rough and rugged fortresses, the product of an essentially elite, masculine warrior society, what today we call a feudal society. But they were also among the finest buildings of their times—secure, well-built residences that supported the complex rituals of noble life. To understand how castle form came to meet castle function, we must look briefly at the castle’s social and economic underpinnings.

As castle design evolved, the great tower was eventually replaced by walled enclosures, which permitted more effective use of troops and better living conditions. The future of castle design lay with the curtain wall, that is, a wall “hung” like a curtain between towers, each of which functioned like a keep.
