11The Great Wall of China, China

Stretching over 13,000 miles, the Great Wall of China is a monumental feat of ancient engineering. Built over several dynasties, primarily during the Ming Dynasty (1368–1644), the wall was constructed to protect against invasions and raids.

Its grandeur lies not only in its length but also in its integration with the natural landscape, snaking over rugged mountains and through vast plains. Walking along the Great Wall offers breathtaking views and a sense of stepping back in time.
