where were motte and bailey castles built in england
Motte-and-bailey castle In England, William invaded from Normandy in 1066, resulting in three phases of castle building in England, around 80% of which were in the motte-and-bailey pattern.[60] The first of these was the establishment by the new king of royal castles in key strategic locations, including many towns.[61] These urban castles could make use of the existing town's walls and fortification, but typically required the demolition of local houses to make space for them.[62] This could cause extensive damage: records suggest that in Lincoln 166 houses were destroyed, with 113 in Norwich and 27 in Cambridge.[63] The second and third waves of castle building in the late-11th century were led by the major magnates and then the more junior knights on their new estates.[64] Some regional patterns in castle building can be seen â€“ relatively few castles were built in East Anglia compared to the west of England or the Marches, for example; this was probably due to the relatively settled and prosperous nature of the east of England and reflected a shortage of unfree labour for constructing mottes.[65] In Wales, the first wave of the Norman castles were again predominantly made of wood in a mixture of motte-and-bailey and ringwork designs.[66] The Norman invaders spread up the valleys, using this form of castle to occupy their new territories.[67] After the Norman conquest of England and Wales, the building of motte-and-bailey castles in Normandy accelerated as well, resulting in a broad swath of these castles across the Norman territories, around 741 motte-and-bailey castles in England and Wales alone.[68]
