The Great Wall of China was built with a variety of materials. In the eastern section of China, it was made out of lime, bricks, blocks of rocks and stones. The western sections of the Great Wall did not employ such durable materials, but rather used mud, straw, grass and pounded earth in wooden frames. This section was built earlier than the brick section. It also depended on which section of the Wall was being built at any given time. For example, while building over the mountain ranges, stones from the mountain were used. While building over the plains, earth was pounded into solid blocks. In the deserts, sanded reeds and juniper tamarisks were used. Tens of thousands of soldiers, peasant workers and even criminals were employed in the process, and thousands of them died, their bodies were also crammed into the wall and built over. Therefore, it could be said that the Wall is also made out of human bones.

Although the extent of the Great Wall is some 6400 kilometers (4000 miles), it is only a maximum of 30 meters (95 feet) in width at its gates, and the material of the wall is similar to the surrounding land. So it would be far too narrow to observe from the Moon. (Even from low Earth orbit, astronauts need binoculars to make it out.)
