Where Did Knights Live in the Middle Ages?

According to the medieval Code of Chivalry, it was the duty of knights to serve their liege lord. They spent most of their time training for battle and increasing their skills in battle axe, two-handed sword, lance or mace. Knights were expected to guard the castle of their lord and support him in warfare. Achieving knighthood took years of training. Most knights were sons of nobles who started as pages in castles and then moved up several steps until they were knighted.
