Answer 1

}Mote and bailey castles appeared in England after the Norman Conquest of 1066. Mote and bailey castles were a common feature in England by the death of William the Conqueror in 1087. Their construction was the start of what was to become a massive castle building programme in England and Wales.

}A few English timber Motte and Bailey style Norman castles had been constructed by Normans who had been invited to England by King Edward the Confessor, prior to the Norman invasion in 1066. However, the vast number of Norman castles were built following the Battle of Hastings and the Norman conquest. The Normans were great builders of castles and fully appreciated the great advantages that a castle would give to a fighting force. Stone Castles took too long to build so Duke William laid plans to build Norman Timber Castles when he mounted his invasion.
