The Great Wall of China is the longest manmade structure in the world. It was built across China from the 3rd century BC to the 17th century AD, and is more than 20,000km long! The Great Wall is much more than a wall – it includes the walls, watch towers, shelters, horse tracks, fortresses, and open passes. It is a UNESCO World Heritage Site, and is one of the great wonders of the world. The Great Wall started out as individual sections, and was joined together during the Qin Dynasty. It is the national symbol of China.
