Watchtowers

The Great Wall of China, Beijing, People's Republic of China

The Great Wall of China, winds up and down across deserts, grasslands, mountains and plateaus, stretching approximately 8,851 kilometers (5,500 miles) across Northern China. With a history of more than 2000 years, some of the sections are now in ruins or have disappeared. However, it is still one of China's most appealing attractions owing to its architectural grandeur and historical significance. Along the Great Wall there are many watchtowers, spaced from less than a kilometer to several kilometers or more apart. This image captures two decaying examples of watchtowers along the wall.
