Belle Isle Park is a nine hundred eighty-two-acre island park in the Detroit River at Detroit, connected by the MacArthur Bridge and notable as the largest city-owned island park in the United States. Its history stretches from French colonial use as Hog Island and the wartime confinement of American prisoners around seventeen eighty through seventeen eighty-two to its later ownership by General Alexander Macomb Jr. Renamed Belle Isle in eighteen forty-five, it was developed into a major public park in the late nineteenth century, with landmarks including the conservatory, aquarium, James Scott Memorial Fountain, and William Livingstone Memorial Light. Today it remains a heavily used public landscape of recreation, architecture, and civic gatherings.
