Tour CBX, Office skyscraper in La Défense district, Courbevoie, France.
Tour CBX is an office tower with 36 floors rising approximately 142 meters in the La Défense business district. Its defining feature is an inclined roofline that distinguishes it from the surrounding structures.
Construction of the tower began in 2002 and was completed in 2005 as part of the district's ongoing expansion. This addition reinforced La Défense's growth as a major business center.
The name CBX comes from the code system used in La Défense's master plan: unlike neighbouring plots, no building was originally planned for this site, so it received the suffix X. The tower was renamed Tour Dexia in 2007 when the bank moved in; in July 2013 the white "DEXIA" letters were taken down from the curved facade, which is now hidden behind the Tour D2.
The building connects directly to the La Défense esplanade through a pedestrian bridge, making it easy to reach the district's transportation network. The location allows visitors to explore other areas of the business district on foot.
The letters "CBX" come from La Défense's plot-code system: the site had no building planned, so it was labelled CBX (Courbevoie, no assigned number). The Dexia name went up in 2007, and the "DEXIA" letters were taken down from the curved facade in July 2013 after the Tour D2 hid them.
