What materials is the Great Wall made of?

The Great Wall is mainly made of earth, stone, wood, tiles, etc. The amount of earth and stone needed to build the Great Wall is huge, and usually they are taken locally. In places with high mountains and steep ridges, stones are taken from the mountains and used for masonry. In plain loess areas, earth is taken locally and rammed.

The Great Wall, also known as the Ten Thousand Li Great Wall, is an ancient Chinese military defense structure. It is a tall, solid and continuous long wall used to limit the movement of enemy cavalry.

The Great Wall is a defensive system with city walls as the main body, combined with a large number of cities, barriers, pavilions and signs. After Qin conquered the six kingdoms and unified the world, Qin Shihuang connected and repaired the Great Wall of the Warring States Period, and it was then called the Great Wall.

The Great Wall spans several provinces

The Great Wall spans 15 provinces, mainly distributed in Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia, Xinjiang, etc. The Great Wall of China has a total length of nearly 10,000 kilometers.

Inner Mongolia has the largest number of Great Wall relics in China, with the most concentrated, most complete and richest content. The total length of the Great Wall is 7,570 kilometers, ranking first in China. Public data shows that during the Spring and Autumn Period and the Warring States Period, Yan, Zhao and other countries built beacon towers and connected them with city walls to defend against invasions from other countries, forming the earliest Great Wall.

Why the Great Wall won't collapse

There are two main reasons why the Great Wall will not collapse. First, the stones used to build the Great Wall are very large and must be carefully selected and strictly controlled before they can be used. Second, the material used to bond the stones is a paste made from glutinous rice, which has very high adhesion. The glutinous rice paste is melted between the stones to prevent cracks and collapse.

Reinforced concrete did not exist during the construction of the Great Wall. Although glutinous rice mortar has high adhesion and good quality, it is also costly and not suitable for widespread use in the construction industry. Therefore, a large amount of manpower, material resources, financial resources and other resources were spent on building the Great Wall at that time.

The Great Wall has been an important military defense project in my country since ancient times. In the past, it was mainly used to resist the invasion of the Huns. Today, the largest part of the Great Wall is located in Beijing, and it has become one of Beijing’s landmark buildings. Tens of millions of tourists visit the Great Wall every year.
