Wall of the Qi State was considered to be the oldest Great Wall in China. This wall traversed the vast land of today's Shandong Province and reached the east of Qingdao, stretching over 600 killometers. Search a Great Wall Tour
During the Spring and Autumn Periods, conflicts increased and the principalities fought with each other for power and territory. Qi was the most powerful state at that time, ruling over a large area of present Shandong Province. However, its reign was gradually threatened by Jin and Lu states as these became stronger. Fights between the states were common and Qi was often defeated. Later, to forestall the invaders, the Qi governors started to build a wall along the Taishan Mountain where Qi bordered the other two states.
However, Chu, which was originally a weak state, emerged as a confident power and was a threat to Qi in the north. In response to Chu's repeated invasions, Qi built another section of wall in its northern boundary. Successive sections were constructed and connected to form an integrated fortification.
Although the original Qi Wall had been destroyed and abandoned, some ruins of it can be found around China's east Shandong province in areas such as Jinnan, Tai'an and Zibo
The Qi Wall served as an example of the ingenuity of the Chinese people.
