Prospect Hill (Jingshan) was an imperial garden in the Ming and Qing dynasties. Built up by earth over time, the hill was once the highest point in the city. Its structural height is 45.7 meters and its altitude is 94.2 meters. Its related architectural complex from the Qing Dynasty in the park remains intact.
The hill used to sit on the banks of the Yongding River but became a detached mound after the river changed its course. In the Liao Dynasty (916-1125), the surplus earth from construction of an imperial palace was piled up on the mound. In the Jurchen Jin Dynasty (1115-1234), a hillock was added to it as the Taining Palace was constructed in the south. In the Ming Dynasty, in order to construct the Forbidden City’s moat and nearby lakes for imperial recreational purposes, more earth was dug out and piled up on the mound to form a higher and grander hill. Meanwhile, the government accumulated coal on the hill in case of a fuel shortage caused by any potential besiegement of the city. Hence, the hill was also referred to as Coal Hill (Meishan).
In 1644, the peasant rebellion troop leader Li Zicheng seized Beijing; in response the reigning emperor Zhu Youjian committed suicide by hanging himself on an old pagoda tree at the eastern foot of Prospect Hill.
