Motte-and-Bailey: The Classic Hilltop Castle

A motte-and-bailey castle is the quintessential early medieval fortress built on high ground.

• Motte: A steep, artificial or enhanced earthen mound topped by a wooden (later stone) keep—the last redoubt and lord's residence.
• Bailey: An enclosed courtyard at the base, surrounded by a timber palisade and ditch, housing stables, workshops, barracks, and stores.
• Defenses: Often a second ditch and rampart encircled the whole complex. Access was via a bridge (often a flying bridge) to the motte and a gatehouse to the bailey.

Introduced by the Normans after 1066, these castles were quick to build (weeks to months) using local labor and materials. They dominated the landscape, controlled key routes, and served as administrative centers. Over time, stone replaced wood, and the design evolved into the great stone keeps and concentric castles of the High Middle Ages.
