The Great Wall
Just like a gigantic dragon, the Great Wall winds up and down. Across deserts, grasslands, mountains and plateaus, it stretches from east to west. It was continuously built from the 3rd century BCE to the 17th century CE on the northern border of the country as the military defense project of successive Chinese empires, with a total length of more than 20,000 kilometers.
It begins in the east at Shanhaiguan in Hebei province and ends at Jiayuguan in Gansu province to the west. Its main body consists of walls, horse tracks, watch towers and shelters. It also includes fortresses and passes.
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 the most appealing attractions all around the world owing to its architectural grandeur and historical significance.
The Great Wall, one of the greatest wonders of the world, was listed as a World Heritage by UNESCO in 1987.
