Tour Sequoia (previously known as tour Bull, and also known as tour SFR or tour Cegetel) is an office skyscraper located in La Défense business district just west of Paris, France. Built in 1990, that 119 meter-tall tower represents the transition between the third and the fourth generation of buildings in La Défense. It's been the first tower to be built with a semi-circular design in the business district. Later, that design will inspire other towers such as CBC, Kupka, Pacific, Société Générale twin towers or Tour CBX. Tour Sequoia has been built in proximity with the CNIT and the Grande Arche.
