Bethlehem Steel in Pennsylvania was once the second-largest steel producer in the world, making it a symbol of America’s industrial might. But after a long decline, the company closed the doors to the Bethlehem, PA plant in 1995. The facility had been abandoned for more than a decade before Spillman Farmer Architects converted it into a magnificent art campus. Dubbed ArtsQuest Center, the 68,000-square-foot building has been converted into a vibrant public space for people to experience arts and culture in a gritty, post-industrial setting.
