The nonprofit National Aquarium opened in 1981, the jewel of Baltimore City's Inner Harbor redevelopment. With a mission to inspire conservation of the world's aquatic treasures, the Aquarium is consistently ranked as one of the nation's top three aquariums and has hosted over 51 million guests since opening. It is Maryland's largest paid tourist attraction, with more than 20,000 fish, birds, amphibians, reptiles and marine mammals living in award-winning habitats. https://www.aqua.org/
