The site of the former Chicago Stadium, 1800 W. Madison St.
A 16-year-old Muhammad Ali—then Cassius Clay—fought in a 1958 Golden Gloves tournament here. "The huge Chicago Stadium, with three boxing matches going on simultaneously under those hot white lights, with screaming, cheering, booing crowds, was the most awesome spectacle I'd ever participated in," Ali wrote in his 1975 autobiography, The Greatest. In his third match in the competition, young Ali lost by technical knockout to Chicagoan Kent Green in the second round of the semifinals, but the two men became lifelong friends afterward. Meanwhile, the old Chicago Stadium—the “Madhouse on Madison,” built in 1929—was demolished in 1994. Its former site (foreground) is part of the ocean of surface parking lots that surround the United Center.
