Chu State Great Wall
Great wall of Chu State was also was called Square Wall .the first Great Wall was built by Chu State .
Chu State was a small state that gradually developed by conquering weak neighbors during the Spring and Autumn Period. To control China and prevent the intrusion of the Jin and Qi states, Chu State built a series of walls along its northern frontier in about 656BC. These boundary markers would eventually evolve into the Great Wall. Shaped like a “U”, the Wall of Chu was referred to as “the Rectangle Wall”.
Entering the Warring States Period, Chu State extended its wall to guard against the attack from other states especially the mighty Qin. As such, the wall of Chu became more integrated and solid. At this point, the site now included the Lushan and Yexian Counties of Pingdingshan City, Wugang City, Fangcheng and the Nanzhao Counties of Nanyang City in Henan Province.
