Because cannons were invented that blew out the walls therefore they were no use
The Roman did not have any castles. Castles emerged after the end of Roman civilisation, during the Middle Ages.
TRebuchet and catapult
Cannon and gunpowder.
They had outlived their usefulness and were no longer needed
it ended because the Victorians discovered bricks so they made houses.......
The oldest medieval castles were made in the 9th century AD. They were made until the end of the middle ages.
The usefulness of stone castles came to an end with the invention of the cannon - the Turks used these with great success during the Crusades - if my memory serves me well.
the invention of the cannon
mote and bailey castles and stone keep castles and Concentric Castles
no it doesnt follow the development of other castles that were built at that time. it is vey unique and different.
the first kind of castles were moat and bailey castles.
The development of firearms ended the castles' endurance. Another reason is when abandoned they could quickly be reduced to rubble by local people using them as a source of dressed stone and other building materials.
