Pier 26 at Hudson River Park, New York City, NY, USA - 2024

The Hudson River Park Trust


The Science Playground at Hudson River Park's Pier 26 is home to two larger-than-life sturgeons, that stretch up amongst the surrounding skyscrapers and are packed with fun learning opportunities!

Immerse yourself in the marine life of the Hudson River through these highly interactive play features, that invite and inspire children to explore and learn. The 24-meter-long creatures can be scaled on the outside and inside, kids can journey through these endangered fish, learning about their anatomy, habitat and nature as they play. 

The sculptures represent an Atlantic sturgeon and a shortnose sturgeon and are designed in collaboration with OLIN and The Hudson River Park Trust. The playground will serve as an extension to the future Hudson River Park Estuarium, planned to be built here.


We always strive to create thrilling playgrounds for all children, regardless of ability or age, which was also an important goal for this project. Our ambition is to avoid a gap between children with challenges and children with many abilities, which means that the playground, on the whole, should offer all kids good play opportunities and motivate them to move and explore the playground.

Throughout the design process, we have focussed strongly on the aesthetic expression, in part to create sculptural and impressive elements in the cityscape and not least driven by a desire to create playgrounds that grab children’s attention - regardless of their abilities and challenges - and inspire them to become part of the adventure. We believe that the visual expression of a playground is of great value for all children.

The playground meets all safety requirements of the ASTM standards and also follow ADA guidelines for accessibility.

We have designed the two structures with multiple ways to enter the two play structures and varying degrees of challenging climbing routes within. The large Atlantic sturgeon is accessible to wheelchair users by way of a ground-level opening and incorporates ramps with grips inside to enable climbing and crawling to the slides for those with limited mobility.

Both fish are designed with multiple accessible features such as sensory elements, ramps, steps and transfer platforms, which all contribute to facilitating hours of play for kids and their families.

The playground is designed as a recreational and educational resource for New York families and it will also serve as the outdoor extension of the environmental programming at the ecology-focused Pier 26 and the future Hudson River Park Estuarium to be built next to the playground.

With such a strong focus on learning, we worked closely with Hudson River Park’s River Project team, who advised on the scientific aspects of the design, helping to integrate science-based, age-appropriate educational features that help bring the sturgeon to life.

At the playground, children learn by more than merely reading about it but by being part of the unique, immersive experience of entering the fish's inner system and becoming more aware of the Hudson River habitat and the endangered sturgeon.

The Pier 26 Science Playground was made possible by a $3.5 million fundraising campaign successfully completed by Hudson River Park Friends in 2021.
