The Great Wall of China actually started as several walls from the 7th century BC. In the 3rd century BC, Qin Shi Huang united the country and became the first Emperor of China. He wanted to protect the northern border of the country. So he ordered people to connect separate walls to make one great wall. It ran for 5,000 km from east to west. Builders used stone, brick and earth. Legend has it, that Nine Dragons helped people with the construction. About 2,000 years later, the Ming dynasty finished the wall. They built watchtowers and fortresses to make the wall stronger.
