Casterly Rock, the ancient seat of House Lannister, is no ordinary castle. Although crowned with towers and turrets and watchtowers, with stone walls and oaken gates and iron portcullises guarding its every means of egress, this ancient fortress is in truth a colossal rock beside the Sunset Sea, a rock that some say looks like a lion in repose when the sun sets and the shadows fall. The Rock has been measured as thrice the height of the Wall or the Hightower of Oldtown. Almost two leagues long from west to east, it is riddled throughout with tunnels, dungeons, storerooms, barracks, halls, stables, stairways, courtyards, balconies, and gardens. The Lords of Casterly Rock have gathered many treasures over the centuries, and the sights of the Rock— especially the Golden Gallery, with its gilded ornaments and walls, and the Hall of Heroes where the costly armor worn by a hundred Lannister knights, lords, and kings stand eternal guard — are justly famed throughout the Seven Kingdoms, even in lands beyond the narrow sea.
