Qin Dynasty (221 B.C. – 207 B.C.)

• Qin Shi Huang was the first emperor of China and is considered as the first Great Wall builder. He was also known as a tyrant and forced men into building the Wall under harsh conditions. It is estimated that over 3 million people were involved. Those 3 million people were over 70% of China’s population at that time.
• Local materials were used to make the walls, similar to the walls in the Zhou Dynasty. The Zhou people used compacted earth to build the walls.
• The oldest section of the Great Wall during the Qin Dynasty was begun in 221 B.C. The construction of it was almost a link, connecting all of the previous and older walls. The length of all the walls during this period was about 5,000 kilometers.
• According to early Chinese historical records, the Qin Great Wall was built in a 10 year period, making 25 miles of wall every month. The estimated cost to build the Qin Great Wall today would be $260 billion.
