The Great Wall of China became a UNESCO World Heritage Site in December 1987. The wall is the longest man-made structure in the world, with a total length of about 13170.7 mi or 21196.18 km. Made over the course of hundreds of years, the wall was built by over 6 different Chinese dynasties, and is over 2,300 years old. Stretching thousands of miles, the Great Wall is the longest man-made structure in the world, but that isn't its only significance. It was important in defending China from northern invasion for centuries, and has become a national symbol, and China's top tourist sight.
