Yuejiang Tower is situated on the top of Shizishan to the northwest of downtown Nanjing, Jiangsu. The river referred to its name is the Yangtze River, which may be viewed to the north, while central Nanjing can be viewed to the south.
In 1360, Zhu Yuanzhang defeated Chen Youliang’s 400,000 forces with his 80,000 army in Lu Longshan, which set up the basis for the reign of Ming Dynasty and for taking Nanjing as the capital. After proclaiming himself as the emperor, Zhu Yuanzhang changed Lu Longshan as the Lion Mountain in 1374. He ordered to build the Yuejiang Tower on top of the mountain and wrote the Note on Yuejiang Tower in person, although the tower was never built.
