G. Fred DiBona Jr. Building

The G. Fred DiBona Jr. Building is a 45-story office tower in downtown Philadelphia with a distinctive blue glass facade accented by granite detailing at street level. The structure rises approximately 625 feet and contains office spaces designed for large corporate operations.

The tower opened in 1990 under the name Blue Cross-Blue Shield Tower and was renamed in 2005 to honor a longtime company leader. WZMH Architects designed the structure during a period of significant downtown development in Philadelphia.

The building functions as a significant regional hub for healthcare administration and employment in Philadelphia. It has become a recognizable landmark that frames the cityscape and draws the attention of people passing through downtown.

The building is located along Market Street in the heart of downtown Philadelphia and is easily accessible by public transportation. Since it serves as a private office tower, visitors can see it best from the street or nearby public viewpoints rather than entering the interior.

In 1997, French climber Alain Robert scaled the exterior of the tower to the 44th floor, soon after a large corporate logo was installed on the facade. The feat drew attention from local media and remains part of the building's less-known history.
