The mall opened its doors to the public August 11, 1992. Even before opening, Mall of America had earned several nicknames, including "The Megamall" (or "The Megamess" during construction), "Sprawl of America", "Hugedale" (in reference to the four major "Dale" shopping malls within the Twin Cities, Rosedale, Southdale, Ridgedale and Brookdale) and, simply, "The Mall".
