The Summer Palace is a popular place for both foreign travelers and local residents. It covers an expanse of 2.9 square kilometers, three quarters of which is the Kunming Lake. The main building is the lyrically named Hall of Benevolence & Longevity. In December 1998, UNESCO included the Summer Palace on its World Heritage List and declared the Summer Palace an “outstanding expression of the creative art of Chinese landscape garden design, incorporating the works of humankind and nature in a harmonious whole.”
