Tour CGI, Office building in La Défense, France

The Tour CGI, also coded CB16, is a first-generation office skyscraper in Courbevoie within the La Défense district. It rises 110 metres with 32 floors, comprising 26 levels above ground, 6 basement levels and a technical terrace on the 28th floor. Its total leasable office area is 27,712 m², and it is flanked by the Aurore, Europe, CBX and D2 towers.

Completed in 1971 as a first-generation tower, it was later known as Tour EDF-GDF, then Tour Logica. It underwent asbestos removal and complete restructuring in 2002-2003, followed by a full renovation in 2018-2019. Its premises were occupied by CGI and Esset from December 2019 to October 2022.

The tower's location code in the La Défense master plan is CB16, which gave the building its earlier name, Tour CB16. It was first called Tour EDF-GDF, then Tour Logica, and took the name Tour CGI from its tenant CGI, which occupied the premises from December 2019 to October 2022 alongside Esset, formerly Foncia IPM.
