Early Medieval Castles

The earliest castles were often simple wooden structures, known as motte-and-bailey castles, consisting of a raised earth mound (motte) topped with a wooden tower or keep, and an enclosed courtyard (bailey) at the base. These early castles provided basic fortifications and served as defensive structures for the local lord or ruler.
