The site has not been updated for a year or so but there is a lot of interesting retail information at Deadmalls.com. You can even purchase your own memorabilia (though I was hoping for something more ghastly)!

Four quick thoughts:

1. The shopping mall was a marvel of the post-World War II suburban era. Today, there are still thriving malls – even in urban locations as they figured out that they needed to play in this game – but plenty of dead ones (27 listed in Illinois alone). The wonder of having all of those stores in one location that is easy to reach by car.
2. Have the shopping malls been replaced by anything? Shopping online is not the same visceral experience. Perhaps it is big box stores: occasionally when I wander into a Home Depot or Costco or Walmart, I am astounded by the vast size, the number of products, and the relatively low prices.
3. There are a lot of efforts to renovate or revitalize shopping malls including turning them into lifestyle centers, adding housing, and incorporating new features like skating rinks. Such efforts will probably succeed in a number of malls..
4. I’m reminded of the portrayal of a dead mall in the book Gone Girl which portrayed it as a suburban wasteland (along with the McMansions). It would be worthwhile to go back to these dead malls sites in a decade or two to see what has become of them. Urban/suburban ruins? New uses?
