Tour Eqho (also known as Tour IBM, and Tour Descartes[1]) is an office skyscraper located in La Défense business district situated west of Paris, France.
Built in 1988, the tower, with a height of 130 metres, belongs to the third generation of towers in La Défense.[2] 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.[3] It now hosts a variety of companies with KPMG taking the most floors.[4]
Bloomberg News reported that the building is nicknamed “the urinal” by real estate brokers because of its distinctive shape.[5]
