Belle Isle Aquarium

This aquarium was opened in 1904 and ran continuously until 2012 being the oldest public aquarium in the U.S. at that time. Reopened in 2012, the historical building's interior features a green glass ceiling giving you the feel of being underwater. When the aquarium operated during Prohibition, a speakeasy was set up in the basement - but later held large fish that didn't fit in the gallery tanks.
