The China Great Wall
The China Great Wall is well-known for its amazingly unique architecture. It is also known as “long Wall of 10,000 Li” in China that extends about 8,850 kilometres (5,500 miles). Ever wondered why the Chinese build the China Great Wall? It was actually designed to keep Mongol nomads out of China. The walls were built of earth and stones in wood frames during the Qin Dynasty. However, the major construction of the “modern” walls actually began during the Ming Dynasty.
The wall was at first built from rammed earth, stones and wood but then bricks were used to build the areas of the wall. In fact, the size and weight of the bricks were much easier to work with compared to earth and stone, so the construction can be completed faster.
