What does a castle do during a siege?

Answer 1

A castle helped protect the people from their enemies by providing a safe heaven, often for Royalty, where people would go for protection during times of war. The strong castle walls would often be accompanied by catapults, archers, and draw bridges to defend against attackers. Often castles would have courtyards where food could be grown and stored if sieges lasted a long time, often trying to outlast the invaders through attrition.
