Unless you grew up in Europe, castles may seem like the stuff of legends, fairy tales and Walt Disney World. Fortunately, these structures that serve as the setting for our favorite childhood movies are inspired by real places, many of which are still standing hundreds or even thousands of years after they were built. Constructed by royals, noblemen, warriors and chiefs, castles were designed to protect occupants from enemy invaders, many of whom were determined to scale even the strongest fortifications in their quest to conquer enemy lands.
