Keilehaven Tidal Park
The Keilehaven Tidal Park in Rotterdam is a pioneering example of how sustainable urban development and rewilding can be combined. The project combines the creation of a city park with the reintroduction of a natural estuarine system in an urban setting. This results in an innovative public space where the delta’s tidal landscape becomes visible and tangible.
Experience nature
The park seeks a regenerative balance between cultural use and natural processes. The tidal movement plays a central role: parts of the park are accessible at low tide but not at high tide. This makes it a unique place where urban dwellers can truly experience nature. Where else in the city can you see a Kingfisher or blooming Spider Marigold?
Citywide strategy
The Keilehaven Tidal Park is part of the broader urban strategy The River as a Tidal Park, which strengthens the river and its banks as ecological infrastructure. Gradually, the river is being transformed into an attractive living environment for humans and wildlife alike. The park also marks the beginning of redevelopment in the surrounding M4H port area. It offers recreational space while enhancing local biodiversity. Through a mix of wet-dry and deep-shallow gradients, the area attracts a wide variety of plants and animals. This makes the river more valuable as a migration corridor and as a place for animals to feed, rest, and reproduce.
Water and soil first
The foundation of the tidal park lies in the 3D design of soil and water. The harbor basin was made shallower to support bottom-dwelling organisms. Underwater structures offer anchorage for plants and shellfish. Terraces at varying heights and flood frequencies develop distinct flora, with only minimal planting (some willows, alders, and rushes), allowing for spontaneous natural growth.
A circular park
The park uses recycled materials from other public works in Rotterdam, such as quay and paving stones to fill gabions. To shallow the basin, bio-based materials like willow bundles and harbour ballast were used. Nature transplantation, a method of moving existing vegetation, was applied to give the park a mature look from day one and enrich the soil ecosystem. This supports a sustainable, biodiversity-focused design approach. The harbour’s cultural history thus becomes the foundation for new nature and a strong sense of place.
