The Key West Aquarium opened in 1934 during the Great Depression as part of a federal public works program aimed at boosting tourism and employment in the Florida Keys. Designed as one of the first open air aquariums in the United States, it used natural seawater pumped directly from the ocean, allowing visitors to experience marine life in an innovative and immersive way.

In its early years, the aquarium served as both an attraction and a research facility, showcasing local marine species while educating visitors about the surrounding waters. Its innovative design allowed fish to live in conditions closer to their natural habitat.

Over the decades, the aquarium evolved to focus more on education and conservation while preserving its historic character. Today, it stands as a living piece of Key West history, continuing to connect visitors with the rich marine life of the Florida Keys.
