Toledo Zoo and Aquarium grew from a single donated woodchuck in Walbridge Park in 1900 into a major nonprofit zoo and botanical garden caring for more than 10,000 animals of 720 species and participating in about 80 species survival programs. After precarious early years and a 1901 fire, it expanded under local leadership and gained a distinctive architectural identity in the 1920s and 1930s through Spanish-inspired buildings and Works Progress Administration projects, including Ohio’s first public aquarium. Financial crisis around 1980 nearly closed it, but recovery led to restoration, new exhibits, and continued growth, leaving it notable for both its animal collection and unusually rich historic architecture.
