The name "Neiwei" (Inner Enclosure) comes from earth or bamboo stockades known as "Wei" (Enclosure). Built during the Ching Dynasty and used for protection against bandits. "Newei" was named when the City government stationed a garrison there. In 1920, although the Japanese changed the written form of "Neiwei", the pronunciation remained the same. Neiweipi used to be Kaohsiung City's largest wetlands. It played an important role in water storage and irrigation and possessed its own unique wetland ecology. The Neiweipi Cultural Park is situated on 41 hectares of land in northern Kaohsiung. It includes the Kaohsiung Museum of Fine Arts, Sculpture Park, Artificial Lake, an outdoor music venue, The Firefly Conservation Area and the Marsh Wetlands Area.
