- Great Wall of China

Several sections of the Great Wall of China, a man-made phenomenon that has become a symbol of Chinese civilisation, can be viewed in the Beijing area.

In Yanqing county in northwest Beijing is the 600-year-old Badaling Fortification, representative of the Ming dynasty sections of the Great Wall. Other sections can be seen at Jinshanling, Mutianyu and Simatai.

The Great Wall, 4,000 miles (6,350km) long, was built in stages from the 7th century BC onwards, snaking its way across the mountains and valleys of five provinces in northern China as a mammoth defence bulwark.
