7 Plaza Tower New Orleans, Louisiana
If you look at the New Orleans skyline, one of the first buildings you will notice is Plaza Tower. The 45-story skyscraper was completed in 1968 and is still the third-tallest building in New Orleans.
Primarily used as an office building, it enjoyed constant use until tenants started complaining about mold and asbestos. Those problems persisted, which led to the tower being vacated in 2002. It was then gutted and environmentally abated to remove the mold and asbestos.
The building was auctioned off in 2011 for an undisclosed amount. It is not known if there are plans to restore the building at the moment. Plaza Tower was the tallest building in New Orleans when it was erected and has been a fixture of the New Orleans skyline ever since.
