Tour Ariane

Tour Ariane reaches 152 meters into the sky with 36 floors, featuring aluminum shields and porthole-shaped windows on its concrete facade.

Architect Jean de Mailly completed this office building in December 1975 as part of the second generation of high-rise structures in La Défense district.

The tower represents the architectural innovation of the 1970s French business district development, marking a departure from earlier urban planning restrictions.

The building accommodates 4,000 users across its office spaces, with 19 elevators serving the various floors throughout the structure.

The 2024 renovation project recycles 90 percent of original glazing and 85 percent of aluminum shields while reducing energy consumption by 30 percent.
