The Great Wall of China was built mainly to protect the Chinese Empire from the Mongolians and other invaders. It was first built in the Seventh Century BC when China was still divided into many small states. The construction of the Great Wall never ceased during nearly all the Chinese fudal dynasties.
The Great Wall of China extends 4,000 miles (6,400 km) westward from the seaside town of Shanhaiguan to Gansu Province.
The majestic Great Wall was built with wisdom, dedication, blood, sweat and tears. It has been estimated that somewhere in the range of two to three million Chinese died as part of the centuries-long project of building the wall.
Nearly everyone has heard of the Great Wall of China. As one of the UNESCO World Heritage Sites in China, The Great Wall is not just a wall, but a symbol of the bravery and wisdom of the Chinese people.
