16. The Great Wall of China
The Great Wall of China is an impressive structure that stretches over 13,000 miles across northern China. Built over many dynasties, it was originally used for defense and now represents China’s rich history and culture. Popular parts like Badaling and Mutianyu, close to Beijing, offer beautiful views and are easy to visit. For a more adventurous experience, less-visited areas like Jiankou and Simatai provide a rugged and authentic way to explore this ancient wonder.
