The Great Wall of China is a masterpiece of engineering, including several chunks of massive walls extending for a hunge length of 3,700 miles (6,000 kilometers) across much of what is China. The Great Wall was begun during the Warring States period of Zhou Dynasty (ca 480-221 BC), but it was the Qin dynasty emperor Shihuangdi (he of the terracotta soldiers) who began consolidation of the walls.
