One of the most famous wonders of the World or the longest wall in the World, The Great Wall of China, is an ancient sequence of a wall situated in Northern China that has an extended history of more than 2,700 years. As a powerful symbol of Chinese civilization, the Great Wall was most possibly built during the Ming Dynasty (1368-1644) & it was also constructed to defend China from its opponents and aggressors from the North, especially the Mongols. In places, the Great Wall is 25 feet tall & 15 to 30 feet wide. Millions of people, including workers, soldiers, slaves, war prisoners, etc. made the Great Wall. There is a myth that the wall can be seen from space, and it is the most significant human-made construction ever built, which has an overall length of 21,196 kilometers (13,170 miles). It was also recorded as a World Heritage by UNESCO in 1987.
