Fantaseas was a chain of indoor waterparks situated in the United Kingdom that opened in the late 1980s, but due to various technical, and financial difficulties closed in the mid-nineties. The first was opened in Autumn 1989 on the outskirts of Dartford in Kent. The building contained six water slides, a lazy river, wave pool, an outdoor heated lagoon as well as a cafe and gaming video arcade. Visible on the skyline from the nearby M25 motorway the building dominated the local landscape and became quite an icon of the town.
