The RSA Trustmark Building, initially known as the First National Bank Building, is a 34-story International Style office tower located in the heart of downtown Mobile, Alabama.[1] It was once called the AmSouth Bank Building after its principal occupant, AmSouth Bancorporation, until 2006. In 2009, its proprietor, Retirement Systems of Alabama, rebranded it as the GM Building.[2] Following a leasing arrangement with BancTrust Financial Group and its affiliate BankTrust, the structure was renamed the RSA–BankTrust Building. BancTrust was subsequently acquired in 2013 by Trustmark Corporation, a financial firm based in Mississippi.[3] The building adopted its current name, RSA Trustmark Building, with Trustmark occupying space including the lobby and floors 25 through 31.[4]
History
The site originally hosted the First National Bank building (constructed in 1913) and the three-story Neo-Renaissance U.S. Customs House dating back to 1853, both of which were demolished in 1963 to make way for the new office tower completed in 1965. This tower held the title of Alabama's tallest structure until Birmingham's SouthTrust Tower overtook it in 1986. It remained Mobile’s highest building until the RSA Battle House Tower was finalized in 2007. For approximately one year, it ranked as Mobile’s second-tallest and Alabama’s fourth-tallest until a spire addition during the Renaissance Hotel renovation in 2008 raised that building’s height to 536 feet.
In February 2009, Retirement Systems of Alabama took ownership and renamed the building. In November of that year, plans were unveiled to renovate the interior from Class C to Class B office standards. The design and engineering firm Goodwyn, Mills & Cawood spearheaded this project, which included replacing all windows with extended mirror-tinted glass panels. These improvements were finished by March 2011. Additionally, the tower features Dauphin's restaurant on its 34th floor, providing sweeping views over Mobile.
