Photographer's Note

The Great Wall was built to keep out invaders from the north, but throughout the years it became useful for other purposes as well. According to Lonely Planet, it worked "very well as a kind of elevated highway, transporting men and equipment across mountainous terrain."

In addition, "its beacon tower system, using smoke signals generated by burning wolves' dung, quickly transmitted news of enemy movements back to the capital."
