Citrus Center, Commercial skyscraper in downtown Orlando, United States.

The Citrus Center at 255 South Orange Avenue is a 281-foot office tower of 19 storeys, topped out in December 1970 and completed in April 1971. Its first five storeys form a parking structure, four enclosed and the fifth open behind parapet walls, with a lobby and tenants on the ground floor. The tower has eight faces, the four corner faces only two windows wide, making it an octagon, and 1,144 windows on floors 7 through 19.

The building was completed in 1971 and became Orlando's first modern skyscraper. It held the title of tallest building in the city until 1986, when newer structures surpassed it.

The dark-blue translucent letters CNA on the parapet were lit light blue at night and were a fixture of the Orlando skyline for years, visible 15 miles away by road. The building's name changed with its main tenant, from CNA Tower to the Citrus Center and later the BB&T building.

The building stands in downtown Orlando on South Orange Avenue and functions as an active office complex. Visitors should know that access is primarily during business hours, as it remains a working commercial space.

The roof, not the top floor, holds a large structure for electrical power switching circuitry, seven elevator winches (six passenger, one freight) and window-washing equipment on rails. The building's eight faces make it an octagon, with the four corner faces only two windows wide.
