The Great Wall of Qi (simplified Chinese: 齐长城; traditional Chinese: 齊長城; pinyin: Qí Chángchéng) is the oldest existing Great Wall in China.[1][2] Construction of the wall started in 441 BC by the state of Qi, to defend itself against attacks from the states of Jin and Yue. Construction ended during the Warring States period and became Qi's defense against enemies states like Ju, Lu, and Chu.[3] The wall stretches from Guangli village of today's Changqing District, Jinan, running across the mountain ridges of central Shandong Province to the Yellow Sea in the present-day city of Qingdao.[3] Its total length has been estimated at 600 kilometers.[4] Most of the wall is still able to be seen.
