The Great Wall of China is a wall that covers much of the northern border of China. If you take the length of the entire wall, plus various branches, it is around 5, miles long!
Beyond Jiumenkou, an offshoot known as the Liaodong Wall continues through Liaoning province and terminates at the Hushan Great Wallin the city of Dandong near the North Korean border. During the Ming, however, bricks were heavily used in many areas of the wall, as were materials such as tiles, limeand stone.
The size and weight of the bricks made them easier to work with than earth and stone, so construction quickened. Additionally, bricks could bear more weight and endure better than rammed earth. Stone can hold under its own weight better than brick, but is more difficult to use.
Consequently, stones cut in rectangular shapes were used for the foundation, inner and outer brimsand gateways of the wall. From the parapets, guards could survey the surrounding land.
Signal towers were built upon hill tops or other high points along the wall for their visibility. Wooden gates could be used as a trap against those going through. Barracks, stables, and armories were built near the wall's inner surface.
Those parts might serve as a village playground or a source of stones to rebuild houses and roads. Various square lookout towers that characterize the most famous images of the wall have disappeared. Many western sections of the wall are constructed from mudrather than brick and stone, and thus are more susceptible to erosion.

In an attempt to further clarify things, the ESA published a picture of a part of the "Great Wall" photographed from low orbit. However, in a press release a week later, they acknowledged that the "Great Wall" in the picture was actually a river.
It was so indistinct that the photographer was not certain he had actually captured it. Based on the photograph, the China Daily later reported that the Great Wall can be seen from 'space' with the naked eye, under favorable viewing conditions, if one knows exactly where to look.
