Aloe Plaza, which is located outside Union Station, is the site of one of St. Louis's favorite works of public art, a grand fountain featuring allegorical representations of mythical female and male figures that represent the coming together of the Missouri and Mississippi Rivers. The rivers' 17 tributaries are depicted as water sprites, mermaids, and fish. This 1940 sculpture was crafted by Swedish sculpture Carl Milles, an apprentice of master French sculptor, Auguste Rodin.
