the Normans changed the design because they thought the defence system was weak so in order to save them selfes they built bigger, stronger and more powerful castles wich we can still see today.
Because what castles used to be made of were not as strong as they are made of now because they had to develop the structure because the weapons that were used against castles in wars had developed stronger aswell!
because the rules were boring....
because weapons destroied them over time
Yes, there were castles almost everywhere. Unfortunately, most were knocked down.
why did England change to having stone keep castles
The Normans' way of life changed after conquering England in 1066, blending their Viking heritage with French culture to create a unique Norman identity. They adopted feudalism and built castles to maintain their power. The Normans also introduced new architectural styles, language, and legal systems to the lands they conquered.
They was made of wood but then they changed to brick. so Enemys couldn't burn them they would of needed a more powerful object.
concentric castles
concentric castles didn't change. They were the last castle built
Becuase of me
Castles don't attack they defend.
that they way that the houses are shape it changes over time
