Motte-and-Bailey Castles: Gradual Evolution from Wood to Stone

There is no single date when motte-and-bailey castles “changed.” Instead, they evolved gradually over centuries.

Timeline

• 10th–11th century: First appear in Europe. Earthen mound (motte) with wooden keep, surrounded by ditched enclosure (bailey) with palisade.
• 11th–12th century: Stone replaces timber on motte (shell keeps, then great towers). Palisades become stone curtain walls.
• 12th century onward: Fully stone castles (concentric designs) supersede motte-and-bailey form.

The transition was driven by military technology (fire, siege engines), economics, and the desire for permanent, prestigious residences.
