Great Wall of China, Chinese (Pinyin) Wanli Changcheng or (Wade-Giles romanization) Wan-li Ch’ang-ch’eng (“10,000-Li Long Wall”), extensive bulwark erected in ancient China, one of the largest building-construction projects ever undertaken.
The best-known and best-preserved section of the Great Wall was built in the 14th through 17th centuries A.D., during the Ming dynasty. Though the Great Wall never effectively prevented invaders from entering China, it came to function as a powerful symbol of Chinese civilization’s enduring strength.
The construction of the Great Wall as it is known today began around 1474. After an initial phase of territorial expansion, Ming rulers took a largely defensive stance, and their reformation and extension of the Great Wall was key to this strategy.
The Ming wall extended from the Yalu River in Liaoning Province to the eastern bank of the Taolai River in Gansu Province, and winded its way from east to west through today’s Liaoning, Hebei, Tianjin, Beijing, Inner Mongolia, Shanxi, Shaanxi, Ningxia and Gansu.
Starting west of Juyong Pass, the Great Wall was split into south and north lines, respectively named the Inner and Outer Walls. Strategic “passes” (i.e., fortresses) and gates were placed along the wall; the Juyong, Daoma and Zijing passes, closest to Beijing, were named the Three Inner Passes, while further west were Yanmen, Ningwu and Piantou, the Three Outer Passes.
All six passes were heavily garrisoned during the Ming period and considered vital to the defense of the capital.
