Hanhipuisto park was originally set up in 1988 on a dredged soil deposit site. Extensive rebuilding work has turned the former sedimentation basins into a park where horizontal dimensions are used to highlight the vegetation on display. The total area of the Hanhipuisto park is around 16 hectares, of which 8.9 hectares comprises built-up parkland.
