The International Amphitheatre was an indoor arena, located in Chicago, Illinois, between 1934 and 1999. It was located on the west side of Halsted Street, at 42nd Street, on the city's south side, adjacent to the Union Stock Yards. The Amphitheatre was also the primary home of the Chicago Cougars of the WHA from 1972-1975. It was originally intended to be only a temporary home for the Cougars, but the permanent solution, the Rosemont Horizon, was not completed until 1980, five years after the team folded and a year after the WHA had gone out of business.
