Several famous landscapes of southern China had been reproduced in the Imperial Gardens. Location The palace was built on a site abundant in fresh water, near the Jade Spring Hill. The region was renowned for its beautiful landscape. Country homes were built here beginning in the 13th century, during the rule of the Yuan dynasty, then in the 16th-century Li Wei of the Ming Dynasty built the Qinghua Yuan estate at the site. Western mansions The most visible architectural remains of the Old Summer Palace can be found in the Western mansions (Xiyang Lou) section of 18th-century European-style palaces, fountains and formal gardens.
