What came after the motte and bailey castle?
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.
