St. Louis Aquarium at Union Station
The unique history of St Louis’ famous 19th-century Union Station was the perfect storytelling canvas and challenge for PGAV designers. The guest journey begins with an overhead immersive display, a clock-themed aquarium featuring colorful fish, and a media-based “train ride” narrated by St. Louis native John Goodman.


Multi-story, multi-species habitats, including a deep-water shark habitat, provide the animals with enriching spaces to thrive. Multiple touch experiences and interactives keep visitors and St. Louisans returning time and again.


While anyone can show you pretty pictures, at PGAV, we have the expertise to turn them into reality. Everything we draw can be built.
Media is a deeply integrated element of the aquarium. From the bioluminescent plankton floating across the floor to the real-time interactive animated show, every moment is crafted to entice wonder and exploration.
