Century III Mall is the third largest shopping mall in the Pittsburgh region. Situated in the southern suburb of West Mifflin, Pennsylvania, the three-level mall contains 1.286 million square feet of retail space with 5 total 2-story anchor spaces. Current anchors include: J. C. Penney, Macy's (Formerly Kaufmann's), and Sears each with 2 floors, and Dick's Sporting Goods with one floor.
Conceived in 1976 as the mall for the next century of the United States, hence the name Century III, Century III Mall was a joint venture project of The Edward J. DeBartolo Corporation and The United States Steel Corporation. The location for Century III was a former US Steel slag dumping ground, referred to as "Brown's Dump." Slag, a waste product of steel making, had for years been transported by rail cars from the mills of Pittsburgh to this once remote valley. The pile grew until it became an artificial mountain, as hard as concrete and large enough to contain a mall (as well as many satellite stores). Many Pittsburgh residents remember the skies being red each night from the slag cars coming to dump the slag. It became a daily spectator event.
