# The Great Wall of China

The Great Wall of China is a huge barrier that spans thousands of miles along China’s historic northern border. Created over millennia, the wall began its life as a series of smaller walls dating back to the 7th century BCE, built as protective barriers against nomadic raids. In 220 BCE, China’s first Emperor, Qin Shi Huang, masterminded the unification of all of China’s walls into one almighty barrier, strengthening and extending the wall to keep out northern invaders.
