Most of the buildings in St Augustine (there aren't really any castles - forts, churches, etc) are made of coquina stone.
· A stone castle would not rot whereas a Motte and Bailey would rot easily as it was made from wood. · Motte and Bailey castles could be knocked down with battering rams, but they would not penetrate a stone castle. · Stone castles had battlements which gave defenders something solid to hide behind, Motte and Bailey had no such thing. · The round towers on a stone castle were thought to bounce of any type of missile but they would destroy a stone keep. · Motte and Bailey castles were very prone to rotting and decay, but Stone castles would not rot or decay. · Stone Keeps could not be burnt down very easily as they were made of stone whereas Motte and Bailey castles could be incinerated very easily as they were made of wood. · Stone castles have high up towers enabling the defenders to fire arrows down at the enemy but the enemy could not fire back, Motte and Bailey castles do not have high enough towers to do this.
Newer castles were made with stone and rounded corners. the reason was that it was an advance round corners were good because they had fewer space to hide and also the shape deflected any catapults or missiles.
Motte and Bailey castles were built out of wood because it was cheap to buy, light to carry and could be built really quickly and with ease. A motte and bailey castle would have been built in a matter of weeks. Also it meant the motte would not collapse
They did this because if anyone in the country protest about the king they can build castles for the protection and for a battle with any other country. They changed over time because some of the stone would get old and rot and also to improve the castles protection.
Motte and Bailey Castles are created on a raised mound which is either natural in formation or built. At the top perimeter of the mound a wooden post fence is built and within this enclosure there is usually a watch tower built. The design probably dates back as far as the neolithic period when hill forts were constructed to protect towns. These type of castles are temporary in nature unlike the stone keep castle which as its name implies is made of more permanent materials and is surrounded by a stone wall. Later versions of stone walled castles employed such structures as gatehouses, moats keeps and watchtowers, including the grander ones having both inner and outer courtyards.
There were not any castles in the roman times as they did not make any
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
castles changed as more and better siege weapons were being devoleped which were better at destroying bigger better castles were needed they started of as tiny motte and bailey castles but turned out to be massive concentric castles
The difference between a stone keep castle and a concentric castle is that a stone keep castle had hardly any defence. The only defence was their high walls. But the concentric castles had loads of walls surounding them. The word 'concentric' actually means with common middle point: describes circles and spheres of different sizes with the same middle point.
The Motte and Bailey was quick to construct, but was generally made of wood. This made it extremely vulnerable to fire-flinging attacks - and also quite temporary, too. Generally, they were built of sandstone or limestone, but the whole castle wouldn't have been made of stone - it was expensive and unwieldy. Costs would have been cut by using wooden roofs, partitions, and supports.
Stone keep castles were first built in Medieval England by William the Conqueror. Stone allowed the castles to be build higher than previous wooden castles. This gave them the great advantage of visibility, allowing defenders to see enemies coming from a great distance.
