Stone.
Stone keep castles were built in 11th - 13th centuries.
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).

Square keep castles (or stone keep castles) were made out of stone; you can probably tell from the name! Hope this helps.

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)
mott and baily castles were made out of wood and stone castles were made out of stone.
This is because the keep itself is made out of Stone. they were built in medieval times.
Motte and bailey castles, Stone keep castles and Concentric castles
Shell keep castles are medieval fortresses that are usually built upon a motte. They are made from stone. Some examples of stone keep castles include the Round Tower on Windsor Castle and the Clifford's Tower on York Castle.
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
