Here are the advantages and disadvantages of Stone Keep Castles (Stone Castles): Advantages

• They don't rot within a few decades but will last for centuries to come
• They don't burn as the castles are made of stone
• They are very strong as the stone that the castles are made from are very heavy
• The Stone Keep Castles have very high walls meaning that any attackers that come can't fire arrows over it, but the defenders are able to shoot arrows back over the walls because they are on top of them
• The towers in Stone Keep Castles are massive meaning that the attackers not to be able to shoot arrows up but enabling the defenders to shoot arrows off the tower
• The walls are a few meters thick making it really hard to knock down
• They have arrow slits in the walls which are useful for the defenders to shoot arrows out of at the attackers
• The drawbridge are usually thick so the attackers battering ram can't get through

• Although the walls are high enough for arrows not being able to shoot over. The attackers can still fire rocks, pigs & other missiles by a trebuchet or a catapult
• The towers are a one way path up to the top so if a few attackers are coming up the tower, the defenders don't have anywhere to go
• These type of castles are very expensive to build unlike their previous castles the Motte and Bailey castles
• Stone Keep castles are also very heavy making them hard to build
• Once getting through the drawbridge there was an open area where all the attacking soldiers could kill the defenders
• People can undermine and knock the corners of the castle down
• They took a long time to build
• More specialized skills were needed to build them

Basically, all in all, the stone keep castles were a very good castle to have a the time given the circumstances that happened at that time.

The Wooden castles were not very strong and they caught fire easily many attackers used fire arrows. A battering ram could be used to breach the palisade. The keep was the last line of defence. As well as this, the wood rots quite quickly.
The walls were made of wood, which made protecting them from fire difficult. The defenders would try cover them with wet hides during an attack, but this would not always work.

They were also vulnerable to attacks by battering ram or catapult.

Strengths:

• Hard to shoot arrows through narrow windows
• Fire can't burn stone
• Battering ram would have extreme difficulty in damaging walls

Weaknesses:

• Catapults can tear the stone
• Ladders can be used to invade castle easily
• Castle defenders won't be able to see afar from low ground

A motte-and-bailey is a form of castle. It was made of wood and many were built in Britain and France in the 11th and 12th centuries. Each took 7 to 14 days to build. There were very few Celtic/pre-norman motte and bailey castles. The Normans brought motte and bailey castles in packages like make your own furniture. The main weakness of the motte and bailey castle was that they were usually wooden and therefore burned easily.

Motte- usually buily by the local English people. About 15 meters high. There could be more than one.

Wodden Bridge- this led from the bailey to the starts climbing the motte.

Bailey- A large yard with storeroom, kitchens, stables and guardrooms. There could be more than one.

Palisade- the wooden fence surrounding the bailey.

Gateway & Drawbridge- the entrance to the bailey, guarded by the baron's soldiers.

Ditch- when filled with water it was know as a moat.

Stone keep castles were built because it wasn't going to burn or rot like Motte and Bailey castles would. Also, it would keep it the castle standing for a long amount of time.Because the Motte and Bailey castles would just burn the stone keep castles were a brilliant idea. They lasted longer, they were better defence though the only down side was that they took a lot longer to build. The wooden Motte and Bailey castles only took a week or two but the stone castles would take months.

Square keep castle are quite strong castles, as for this they built lots of them for defence the stronger the castle the better defence because square castles have round towers in each corner the pressure spreads every where and not in one place so the castle does not collapse.
