It is that they have been made into concentric castles
Because they have.
Norman castles changed from Motte and Bailey castles which were made out of wood to Stone Keep castles made out of stone. They changed the castles in this way because of these reasons: * Stones stronger than wood * Stone, unlike wood, doesn't burn * Wood rots withing a few years but Stone will last for centuries * Stone Keep castles had higher up walls meaning that attackers couldn't fire arrows at them * Stone Keep castles had really tall towers that the defenders of the castles could easily fire off, but there's no way that the attackers would be able to fire up at them
the 12th century castles changed from wooden motte and bailey castles. as you know, wood rots and can burn easily, so they changed some of them in to stone keep castles. these were a lot stronger and did not burn as they were made from stone.
stone castles were built with stone
they changed to concentric casles so that enemies couldnt go underground and the whole castle would fall
Motte and bailey castles, Stone keep castles and Concentric castles
No, all castles are different in some way. These are the different types of castles: * Motte and Bailey castles (made out of wood) * Stone keep castles or just stone castles (made out of stone) * Concentric castles (also made out of stone)

Castle design changed because William the Conqueror first wanted stone castles and they were built. Then came along Edward I and he wanted concentric castles. it started with a motte and bailey castleCastles have a changed a lot since medieval times. It used to be Motte and Bailey castles built from wood but then William the conqueror started building castles from stone. They used stone because it was:StrongCouldn't burnCant be knocked overGood Protection
Stone castles were built because they could not burn down as ealsily as wood castles can.
This depends on what type of castle your referring to. In the Norman times, there were two different types of castles built. There were Motte and Bailey castles and Stone keep castles (Stone castles). The Motte and Bailey castles were made out of wood and the Stone keep castles were made out of stone (obviously).
