It is a popular myth that the great wall of China can be seen from the naked eye from space. However, the truth is that you are able to see it with assistance from technology such as a high-tech lens. During the Cultural Revolution in China which took place between 1966 to 1976 bricks from the wall had been used to build homes, bridges, walls, farms, reservoirs and other buildings. Apart from some minor projects, no major restoration work has been required to be done on the wall.
