Harbor Wetland / Ayers Saint Gross

The National Aquarium has an ambitious mission to inspire the conservation of the world’s aquatic treasures. With a prime location in Baltimore’s Inner Harbor and a goal of transforming its campus into a Chesapeake Bay demonstration landscape, the aquarium worked with Ayers Saint Gross to produce a sustainable and high-performing floating wetland to expand the habitat on its campus. Opening in 2024 between Piers 3 and 4, the Harbor Wetland will open to the public as a free exhibit on the National Aquarium campus. The 10,000-square-foot habitat will allow visitors to immerse themselves in a salt marsh habitat like those that existed in this space hundreds of years ago.
