Bank of America Tower is a skyscraper in the downtown area of Jacksonville, Florida, at the northwest corner of Bay and Laura streets. At 617ft, it is the tallest building in Jacksonville, and the eleventh-tallest in Florida . It was built as the headquarters of Barnett Bank and originally named Barnett Center, but the name was changed in 1996 when Barnett was acquired by NationsBank, which soon merged with Bank of America. The 42-floor structure was designed by German-American architect Helmut Jahn, and is constructed of reinforced concrete.
