I recently visited a nearly empty shopping mall in a nearby suburb. The suburb just recently bought more of the property in the hopes of redeveloping the mall into something more productive for the community. On this visit, here is part of what I saw in the mall:

On this winter day, there were at least a few people walking laps around the mall. Others sat in the empty food court. Security walked around.

The directory was about 5-6 years old. At that point, the mall still had a lot of retailers.

In the background of the image, you can see the Sears sign. Almost all of the anchor stores are long gone. Most storefronts are empty. The movie theater is shuttered.

The decline of this mall did not happen immediately. Combine online shopping, lots of shopping options in the Chicago region, and COVID-19 and you get a nearly empty mall. And it will take years to redevelop the property and incorporate the new elements into the community.
