Wanderlust World Wanderlust World Stone keep castles—dominant from the 11th to 13th centuries—represented the pinnacle of Norman military architecture. Their design balanced defense, residence, and symbolism in a layout that evolved from motte-and-bailey predecessors into the iconic strongholds dotting Europe.
The Keep (Donjon): The heart of the castle—a massive rectangular or polygonal tower (often 20–30m tall, walls 3–4m thick). Ground floor: storage/well. First floor: great hall. Upper floors: lord's chambers, chapel. Roof: fighting platform with crenellations.
Curtain Walls: Thick stone walls enclosing the bailey, topped with wall walks and crenellated parapets for defenders.
Towers: Projecting mural towers (square, round, or D-shaped) flanking walls and gates, providing enfilading fire.
Arrow slits (loopholes): Narrow exterior, wide interior—maximizing field of fire, minimizing exposure.
Machicolations: Projecting stone galleries with floor openings—dropping stones, boiling liquids, or projectiles on attackers at the wall base.
Moat: Wet or dry ditch preventing undermining and siege tower approach.
Drawbridge and portcullis: Controlled entry; portcullis (iron grille) could drop instantly.
Gatehouse: Heavily fortified entrance complex with murder holes, guardrooms, and often a barbican (outer defense).
Bailey contained kitchens, stables, workshops, barracks, chapel, and well—a self-sufficient community during siege. The keep's great hall hosted feasts, courts, and administration.
Concentric castles (multiple wall rings) succeeded keeps. Gunpowder artillery eventually rendered high vertical walls obsolete, ushering in low, thick trace italienne fortifications. But stone keeps remain the archetypal medieval castle—symbols of feudal authority etched in stone.
