Beihai Park was an imperial garden and now a public park located to the northwest of the Forbidden City in Beijing. First built in the 11th century, it is among the largest of all Chinese gardens and contains numerous historically important structures, palaces, and temples. Since 1925, the place has been open to the public as a park. It is also connected at its northern end to the Shichahai.
The park has an area of more than 69 hectares (171 acres), with a lake that covers more than half of the entire park. At the center of the park is an island called Jade Flower Island, whose highest point is 32 meters (105 ft).
Beihai literally means "Northern Sea". There are also corresponding Central (Zhonghai) and Southern (Nanhai) "Seas". These latter two are joined inside a complex of buildings known after them as Zhongnanhai; it is the home of China's paramount leaders.
The Beihai Park, as with many of Chinese imperial gardens, was built to imitate renowned scenic spots and architecture from various regions of China; the taihu lake ,the elaborate pavilions and canals in Hangzhou and Yangzhou, the delicate garden structures in Suzhou and others all served as inspirations for the design of the numerous sites in this imperial garden.
The structures and scenes in the Beihai Park are described as masterpieces of gardening technique that reflects the style and the superb architectural skill and richness of traditional Chinese garden art.
