West Lake is a freshwater lake in Hangzhou, China. It is divided into five sections by three causeways. There are numerous temples, pagodas, gardens, and natural/artificial islands within the lake. Gushan is the largest natural island and three artificial islands: Xiaoyingzhou, Huixin Pavilion, and Ruan Gongdun stand at the middle of the lake. Leifeng Pagoda and Baochu Pagoda are separated by the lake. Mirroring each other, the basic pattern of "one mountain, two towers, three islands, three banks, and five lakes" is formed.
West Lake has influenced poets and painters throughout Chinese history for its natural beauty and historic relics, and it has also been among the most important sources of inspiration for Chinese garden designers. It was made a UNESCO World Heritage Site in 2011, described as having "influenced garden design in the rest of China as well as Japan and Korea over the centuries" and reflecting "an idealized fusion between humans and nature".
