More than two thousand years ago, the West Lake was a part of Qiantang River. Due to sediment deposition, sand mouths gradually formed at the foothills of Wushan Mountain and Baoshishan Mountain in the north and south of the West Lake. After that, the two sand mouths gradually moved closer and finally became a sandbar, and an inner lake, the West Lake, was formed on the west side of the sandbar. This time is probably the Qin and Han Dynasties. Zhang Dai's Dream of the West Lake records: "The Great Stone Buddha Temple, an old historical research, Qin Shihuang swam eastward into the sea, and the cable boat was on this stone." The Great Stone Buddha Temple mentioned here, that is, under the Baoshi Mountain on the north side of the West Lake, still has the scenery of "the boat stone of Qin Shihuang".
West Lake is a complex of natural landscape, cultural relics, ancient temples and pagodas, stone carvings and new parks and green spaces. Some lakes are not wide and calm as a mirror; The mountain is not high and winding; Surrounded by lakes and mountains, the natural scale is coordinated and charming. "Clouds on three sides and a city on one side" is the characteristic of West Lake. The construction of West Lake Garden not only highlights the uniqueness of West Lake scenery, but also pays attention to the integrity in harmony with local characteristics.
