The US Bank Center is a highrise in Phoenix, Arizona. It is the second tallest building in the state of Arizona. Built in 1976, it is tall. When it was built, it served as the headquarters for Arizona Bancwest, parent company of The Arizona Bank, which (after Arizona passed legislation allowing for interstate banking) was acquired by Los Angeles-based Security Pacific Bank in 1986 (itself in turn acquired by Bank of America in 1992). Bank of America then occupied the tower until 2000 when the Bank of America Tower was built at the Collier Center. In January 2005, this tower was renamed U.S. Bank Center and underwent a modest renovation to reflect the building's newest and largest tenant. New ground-floor restaurants were added and the building was repainted; the restaurants have since closed. The new U.S. Bank signs were installed in February 2005.
