The Great Wall of China

The Great Wall of China is a series of stone and earthen fortifications in northern China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire from Xiongnu attacks during various successive dynasties. Since the 5th century BC, several walls have been built that were referred to as the Great Wall. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; it lay farther north than the current wall, which was built during the Ming Dynasty.


The Great Wall currently stretches over approximately 6,400 km (4,000 miles) from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total; a more recent archaeological survey using advanced technologies points out that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi). At its peak, the Ming Wall was guarded by more than one million men. It has been estimated that somewhere in the range of 2 to 3 million Chinese died as part of the centuries-long project of building the wall.


The Great Wall was key to protecting agriculture and resisting cavalry of the Huns and other warrior tribes from the north. The advantages of the enormous barrier diminished with the advancement of gunpowder and other weaponry.


The wall was originally built of stone, wood, grass and earth. In the Ming Dynasty bricks were produced in kilns set up along the wall. The bricks were transported by men carrying them on their backs, donkeys, mules and even goats had a brick tied to their head before being driven up a mountain.


The Great Wall of China was built over more than two thousand years. Construction on the first section began between the 7th and 6th century BC, and the last work on the wall was done between the 14th and 17th centuries.
