The Great Wall of China was built in the 7th century BC. Its main purpose was to protect the states of China from northern invaders.

The construction of the Great Wall continued for many years, until the beginning of the Qing Dynasty in 1644.
Today, the Great Wall of China, one of the Seven Wonders of the World, attracts tourists from all around the world. Dignitaries and celebrities have visited the humongous structure.
