Belle Isle Aquarium - early 20th-century aquarium on Belle Isle

Belle Isle Aquarium opened in 1904 on Belle Isle and operated for a century before closing in 2005; it reopened to the public in 2012 under new management. The aquarium's 1904 building is often cited as the oldest aquarium building in the United States, though claims about being the single 'oldest aquarium' are sometimes debated depending on definitions and continuous operation. The facility remains a distinctive historic attraction on Detroit's island park.
