만리장성: The Great Wall of China

The Great Wall of China

Beginning in the 7th century BC, a series of massive defensive fortifications were constructed along China's northern border. Built to protect China from northern attacks, the walls stretched out for thousands of kilometers, many joining together to become the Great Wall of China. Over several centuries, the wall and thousands of supporting structures were built across mountains, deserts, and rivers, eventually stretching more than 20,000 kilometers in length. Sections of the wall near large cities are well-maintained, but many remote areas are slowly being reclaimed by nature. Gathered here are images of the Great Wall over the years, from its westernmost pass at Jiayuguan to where it meets the sea in Qinhuangdao.

Unlike other Great Wall sites nearer to Beijing which have been restored for tourism, the wall around Dajingmen Gateway, which marked China's northern border dating back to the early Ming Dynasty (around 1368) and rebuilt again in 1546 during the Qing Dynasty, has been left largely untouched.(Frederic J.

Chinese hikers make their way up a section of the Great Wall that is decaying and overgrown with vegetation located near Xiang Shui Hu village, located 80 km (50 miles) northwest of Beijing, on September 30, 2012. Voted one of the New Seven Wonders of the World in 2007, the 6,400 km (4,000 miles) wall draws millions of tourists every year, mostly to restored sections near the capital, Beijing. But away from the tourist trail, some parts of the wall are being allowed to crumble away. (Reuters/David Gray)
