The Great Wall of China is one of the most iconic and recognizable historic sites in the world. Stretching over 13,000 miles, it was originally built to protect Chinese states and empires from nomadic invaders. Construction of the wall began as early as the 7th century BC and continued through various dynasties, with the most well-known sections built during the Ming Dynasty (1368–1644). Visitors can explore different sections of the wall, such as the restored areas near Beijing, including Badaling and Mutianyu, or the more rugged, less crowded sections like Jiankou and Simatai. Walking along the Great Wall offers stunning views of the surrounding landscapes and a deep sense of history, as you follow in the footsteps of the soldiers who once guarded this monumental structure.
