The “Mystery of Steel” is the film shown at the Heritage Discovery Center’s Mystery of Steel Exhibit. This spectacular, 3-story Iron & Steel Gallery is New in 2009. The film tells the story of the early days of the steel industry, and Johnstown’s role in transforming America into a modern industrial nation. Using animations, historical photography and re-enactments, the film shows how steel is made, and some of the major technological innovations that were developed in Johnstown. Most importantly, the film includes amazing footage of the Bethlehem steel mills in Johnstown that was shot in 1992, just a few weeks before the mills closed. The gallery’s theater, where the film is shown, features a 30-foot screen for the film, and is equipped with infrared heaters and low-frequency speakers to allow viewers to feel the heat and rumble of the steel mills as they watch.
