The Great Wall of China, which stretches over 20,000 kilometers from the Yellow Sea in the east to the Gobi Desert in the west, is well-known worldwide and plays a significant role in the decision of many people to travel to China. With more than 25,000 battlements winding around treacherous mountain peaks and dense forests, the UNESCO-listed wall, which is 7 meters wide and 6 to 14 meters high, dates back more than 2,300 years.
Despite what many people think, it is actually a series of sections with mountains that act as a natural defense, rather than a single, lengthy wall. Furthermore, although it's still a common misconception, you cannot see it from space!
