Built in 1988, the tower, with a height of 130 meters, belongs to the third generation of towers in La Défense. The tower takes the shape of a parallelepiped in which a semi-cylinder would have been extruded on the main façade. Tour Descartes used to host the French headquarters of IBM Corporation until 2010.
