Motte and bailey castles were first built in Britain after the Norman Conquest of 1066. The term comes from the French word motte, meaning mound, and bailey, meaning enclosure. These types of castles featured a keep - a fortified tower - which was built on top of a steep mound of earth that could be up to 24 metres high. The motte was surrounded by a ditch for added protection, making it very hard for potential attackers to cross and run up the sides in one go.
At the bottom of the motte was the bailey, a walled area of land, which included buildings such as kitchens, stables and soldiers’ quarters. Surrounding the bailey would be a moat, a deep ditch filled with water providing added security against invaders.
