Motte and Bailey castles
the motte and bailey was secure because they had the wooden fence around the whole castle and the motte was high on its hill, which made the enemies not able to climb. The bailey had a d shaped ditch which also made the enemies fall in and not be able to attack.
The castles that came after Motte and Bailey Castles were Stone Castles. This was an improvement to Motte and Bailey Castles because Motte and Bailey castles were made out of wood. Wood burns easily, rots quickly and isn't very strong. Stone castles, however were made of stone(obiously). Stone doesn't burn easily, doesn't rot and is very strong.
