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 (孤山) is the largest natural island and three artificial islands: Xiaoyingzhou (小瀛洲), Huixin Pavilion (湖心亭), and Ruan Gongdun (阮公墩) stand at the middle of the lake. Leifeng Pagoda (雷峰塔) and Baochu Pagoda (保俶塔) 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.
