The Crack Stacks of Minneapolis.
When I was last in New Orleans (2003), the Plaza Tower was vacant.
Edit: Apparently it still is.

[IMG]The building has been unused since 2002 because of environmental problems such as toxic mold and asbestos. In March 2005, the Plaza Tower was purchased by Giannasca Development Group LLC for $4 million. The Giannasca Group planned a $120 million renovation to convert the office tower into a 197-unit condominium tower with an entirely new facade. However, after damage due to Hurricane Katrina, the group was involved in faulty appropriations of insurance money that had been issued after the storm, causing the group to sue one another and default on the mortgage[/IMG]
