Why were castles important to the Normans?

They were helpful when it came to protection. most castles had moats which made it hard to get to the castle. The moats were to deep to walk through, and to wide to swim, there was a draw bridge so that people could get in and out of the castle and across the moat. Most castles were made of a smooth stone. this meant that it could not be scaled or burned. castles were typically well stocked in food and drink so that the people of that country of town would have enough food during an attack.
