The First National Bank Building is a skyscraper located in the Financial District of Boston, Massachusetts, USA, property of the First National Bank. The skyscraper, rising 591 feet (180 m) and 37 floors, is Boston's sixth-tallest building. The building was completed in 1971, and formerly served as the World headquarters of FleetBoston Financial (and the Bank of Boston even earlier). The building now houses Bank of America offices.
The design of the First National Bank Building is unusual, as it has a bulge of several stories near its base. The architect of the skyscraper, Campbell, Aldrich & Nulty, designed the building with the bulge in order to give pedestrians a wider view of the street but at the same time provide the building with more floor space at higher levels. The skyscraper is considered to have an Art Moderne style.
