Located in the eastern part of the Zhanyuan Garden, the History Museum of Taiping Heavenly Kingdom (Taiping Tianguo) was completed in 1956. At the beginning of the Ming Dynasty (1368-1644), Emperor Zhu Yuanzhang built and bestowed the Zhanyuan garden to his brave and loyal general. In 1853, after Taiping Heavenly Kingdom chose Nanjing as its capital, the garden was the residence of East King of the Kingdom. In 1864, the garden was demolished in warfare, and soon rebuilt in 1865 and 1903.
