These fortified structures were often built to protect people of nobility or royalty. Castles originated in the 9th and 10th centuries in Europe. They were used to launch attacks on enemies or as a defense against attackers. Many castles protected important trade routes helping countries to control their territory. Castles were built into the 15th and 16th centuries when gunpowder and artillery became powerful enough to break through their thick walls.
