What Are Castles and Knights?

＂Castles may conjure up a romantic fairy tale world; however, in real life, during the Middle Ages, castles were fortresses, providing shelter and protection for the lord as well as for the peasants who lived on his land. For an army, a lord depended on young soldiers in armor called knights who spent years at the castle learning the skills of warfare＂--
