Motte-and-Bailey Castle

Timeline

1. 900–1000Normandy · NormandyIn the 10th century, Norman nobles raised mounds within their domains and erected wooden towers on top, enclosing courtyards with ditches and wooden palisades, forming the standard motte-and-bailey layout. With short construction times and adaptation to local timber resources, it quickly became a symbol of lordly power.
2. c. 1025–1100England · EnglandIn the early 11th century, castle density increased within the Norman duchy. After the Norman Conquest of 1066, William I built motte-and-bailey castles on a large scale in England to suppress resistance and control key routes; archaeology has confirmed hundreds of sites of this form.
3. 1050–1100Southern Italy · Southern ItalyWhen the Normans established rule in southern Italy and Sicily, they used motte-and-bailey castles as forward strongholds; the crusaders likewise rapidly constructed similar castles along their routes to control supply lines, demonstrating the tactical mobility of this form.
4. 1100–1200Welsh Marches · Welsh MarchesAdvances in siege techniques and the threat of fire in the 12th century prompted lords to rebuild wooden towers as stone keeps. Mounds were retained, but wooden palisades gradually gave way to stone walls, and the motte-and-bailey as a distinct form faded away, though its spatial layout influenced later castle design.
