the Great Wall

The Great Wall (长城) rises from Shanhaiguan, northeast of Qinhuangdao City in Hebei Province on the east coast and falls with the contours of the mountains westwards, crossing nine provinces, municipalities and autonomous regions over 6,700 kilometers, to end at Jiayu Pass, southwest of Jiayuguan City in Gansu Province.

Building of the wall began during the Spring and Autumn Period (770-476 BC) and the Warring States Period (475-221 BC) of the Eastern Zhou Dynasty. Ducal states at that time built walls to defend their individual territories. After the First Emperor of the Qin Dynasty crushed all rival states, he founded the first centralized and unified dynasty in Chinese history. To consolidate the country and ward off invasion by ethnic minority tribes in the north he had the walls linked and extended, giving rise to the 5,000-kilometer-long Qin Great Wall. Later dynasties from Han (206 BC – AD 220) to Ming (1368-1644) continued to build and improve the wall, extending it by more than 1,000 kilometers to its present magnitude.

The Great Wall comprises walls, passes, watchtowers, castles and fortresses. The walls are made of large stone blocks. From east to west, the sections at Shanhaiguan, Jinshanling, Mutianyu, Badaling and Jiayuguan have become popular tourist attractions.

Most of The Great Wall that we see today dates back to the Ming Dynasty. The best-preserved and most imposing section is at Badaling near Beijing city. This section, located at the head of the Juyongguan Pass, is made of large blue bricks and has an average height of 7.8 meters. Five to six horses can be ridden abreast along it. At regular intervals there is an arched door giving access to the top of the wall. The walls feature regular lookout holes, window embrasures and castellated crenels. Beacon towers for passing on military information also appear at fixed intervals. All of these emphasize the important role of the Great Wall in military defense.

As one of the most magnificent ancient defense works, the Great Wall was put on the world cultural heritage list in 1987.
