The Great Wall, one of the greatest wonders of the world, was listed as a World Heritage by UNESCO in 1987. Just like a gigantic dragon, it winds up and down across deserts, grasslands, mountains and plateaus, stretching approximately 13,170 miles (21,196 kilometers) from east to west of China.

With a history of more than 2,000 years, some of the sections are now in ruins or have disappeared. However, it is still one of the most appealing attractions all around the world owing to its architectural grandeur and historical significance.
