Home / Great Wall / History / Qin Dynasty. The Great Wall of the Qin Dynasty (221BC-207 BC) was built during the reign of Emperor Qin Shi Huang, along the country's northern border to prevent the invasion of Huns. In 221BC, Emperor Qin Shi Huang unified China for the first time after annexing six states.
The Great Wall of China is a long man-made wall built using tamped earth, brick, stone, wood, and other materials. The purpose of building the Great Wall of China was to keep out invaders and check military intrusions. It now acts as a tribute to the Chinese who were responsible for building this wall. The wall runs from Shanhaiguan in Hebei province (in the east) to Jiayuguan in Gansu province (in the west).
