Nassal helped bring the St. Louis Aquarium at Union Station to life through custom rockwork, themed exhibit fabrication and immersive environmental design. Located within the historic St. Louis Union Station train shed, the aquarium provides guests with interactive experiences that showcase aquatic ecosystems from around the world.

Home to more than 13,000 aquatic animals, the aquarium features a variety of freshwater and saltwater habitats, including a 250,000-gallon shark exhibit and immersive otter habitat. These environments create engaging opportunities for guests to connect with wildlife while learning about conservation and aquatic ecosystems.

Nassal fabricated and installed custom rockwork, themed environments and interactive exhibit elements throughout the facility. Scenic features were carefully designed to replicate natural habitats while supporting both animal welfare and guest engagement.

Interactive exhibits, educational components and immersive storytelling are woven throughout the attraction, creating memorable experiences for visitors of all ages. The project highlights Nassal's expertise in aquarium construction, custom rockwork, exhibit fabrication and immersive environments for aquariums, zoos and educational attractions.
