A once-gilded age of retail under one roof is going, going, gone. The latest casualty of the retail apocalypse is a once-futuristic mall built upon the ruins of the steel industry.

Now that mall, such a marvel of the retail future it was dubbed ‘Century III,’ is headed for the wrecking ball in West Mifflin, Allegheny County.

Just one of the once-bustling, 3-story mall’s 200 stores remains – J.C. Penney.

And as the Pittsburgh Post-Gazette reports, the current mall owners’ redevelopment plans involve razing the sprawling, boarded-up mall all around the lone surviving store and rebuilding the 410-acre site as a mixed-use development.

Reclamation projects aren’t new for the Century III Mall site. It once was home to a towering 70-ton steel slag pile in the golden age of Pittsburgh’s steel industry, the Post-Gazette reports.

U.S. Steel Corp. sent the tons and tons of steel slag to the site by rail, piling it high as a monument to U.S. manufacturing might.

And when the steel industry rusted, the site was reborn as a retail mecca.

But not just any mall. A shiny, futuristic and awe-inspiring enclosed shopping center that would come to define conspicuous consumption of the go-go 1980s.

Here’s how the Post-Gazette describes what was dubbed the Century III Mall:

The 1.3-million-square-foot, $100-million Century III mall opened in October 1979. It was developed beginning in 1976 by USS Realty partnered with Edward J. DeBartolo Corp. of Youngstown.

At the time, the Pittsburgh Press said the mall was ranked as the largest in Pennsylvania. Anchor tenants included some notable retail names — Gimbels, Joseph Horne Co and Kaufmann’s — as well as standbys like J.C. Penney, Sears and Montgomery Ward.

At its peak, Century III Mall boasted 200 stores and restaurants.

Now just J.C. Penney remains.

The rest of the mall is headed for the dustbin of history, yet another remnant of the ongoing retail apocalypse to be swept away.

But not forgotten.

As the Post-Gazette writes, these mega malls will remain fixed in the consciousness of the crazed consumers who flocked to these climate-controlled shopping havens. They’re the retail palaces where mall walkers traipsed and teenagers trolled the opposite sex.

Soon the memories will be all that’s left.
