"Great Wall of China"

Shi Huangdi was credited with linking the various sections of the wall, which was then known as the Wan Li Chang Cheng (Ten Thousand Li Long Wall), to form what is now known as the Great Wall of China. It twists and winds along hill crests, gorges, and rivers. Its length extends 3,000 miles westward: from the China Sea town of Shanhaiguan to Gansu province. To put this in perspective, it is equivalent to the distance from Los Angeles to Boston, or from London to beyond the Urals mountain chains that separate Europe from Asia. LINK
