They used lime mortar, and the workers built brick and cement factories with local materials near the wall. Over the ages, the wall used around 100 million tonnes of brick, stone, and mud. An impressive feat for a structure that was built before modern construction machinery.
How Was Great Wall of China Built?
The Great Wall of China is one of the most iconic and impressive structures in the world. It was built to keep out invading armies, and is the longest man-made structure in the world. Built over a period of more than 2,000 years, the Great Wall is an amazing feat of engineering and a testament to the ingenuity of the Chinese people.
The original sections of the Great Wall were built during the Warring States period (722-479 BC), when several Chinese states were competing for supremacy. The main purpose of the wall was to keep out the nomadic tribes of Central Asia, such as the Xiongnu.

During this period, the wall was made of stone and bricks, and its length was increased to around 13,000 miles.
The construction of the Great Wall was an incredibly arduous process. Hundreds of thousands of laborers were conscripted to work on the wall, and many of them died during the process. The wall
