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.......
Medieval castles were built in 1067.(in the time of the Normans)
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
