Default Beijing Great Wall

Built for national defense, the Great Wall had an indelible function for keeping invaders out of China on its northern boundary. There are high towers on the great wall where fires would be lit to send signals warning of invasion, then horses and soldiers could be moved quickly along the wall to counter the attack.
