Birmingham just a few years ago was one of America's biggest banking centers. AmSouth, Regions, and Southtrust were all headquartered in downtown. Of course, Wachovia bought Southtrust, and AmSouth merged with Regions, and this has somewhat hurt the city.
When driving along I-65 in Birmingham, for the past 15 or more years, I have yet to see a year that does not have at least 2 tower cranes working on something over there. That campus is just huge, and I wish FSCJ Downtown would start to go vertical as UAB has.
