The Great Wall of China is considered one of the New Seven Wonders of the World, and for good reason. With fortifications spanning a total distance of 21,196.18 km (13,170.70 mi), the wall stretches along China’s northern borders and is considered one of the most impressive architectural accomplishments in history.
