It is that they have been made into concentric castles
nice
they changed to concentric casles so that enemies couldnt go underground and the whole castle would fall
Because they have.
No castles have been built since the middle ages
Yes Castles have changed through time to midevil castles to modern day castle in the U.S or Britain. But People call modern castles mansions.
Nothing changed
1300 that's when they changed
I dont know how they changed the purpose of the castles between 1300 and 1400
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.
over the years castles have changed from being made of wood , for its light weight , to stone for its sturdiness. castles have changed because of both advances in technology and the fact of the enemy's getting smarter and able to defeat the new castles after their advances. the shapes of the castles have also changed to . for example on the motte and bailey castles the shape of the keep changed from being a square shape to being a round shape . this changed because the corners on the square allowed less viewing , making it a circle allowed the people inside to view from all angles, being able to watch out for the enemy's. although the shape was good on the motte and bailey castles, the material was not very good as wood could be burnt and broken easily. they needed to find a new material that could overcome the enemy's effort's. this is when stone castles came into use. the stone was good as it could not be burnt or broken easily, but they would have to change the shape of the castle as the workers would not be able to haul the large stones up the mound of earth on the motte and bailey castles. castle development went in this order: motte and bailey castles stone keep castles concentric castles quadrangular castles
because they have different people in charge of different castles and one persons idea was the best so castles changed for ever.
