As we all know, the Great Wall is the treasure of China - even the world. It really is a great masterpiece of mankind, with its beautiful scenes and grand construction. What many people may not know, however, is that in different periods of Chinese history the material of the building the wall is different in different areas.
Before the use of bricks, the wall was mainly built from earth, stones and wood. Due to the large quantity of materials required to construct the wall, the builders always tried to use local sources. When building over the mountain ranges, the stones of the mountain were exploited and used; while in the plains, earth was rammed into solid blocks to be used in construction. In the desert, even the sanded reeds and juniper tamarisks were used.
