Tour First (previously known as Tour UAP between 1974-1998, and as Tour AXA between 1998-2007) is an office skyscraper in Courbevoie, in La Défense, the business district of the Paris metropolitan area. The tower was built in 1974 by Bouygues for the UAP insurance company. The building was 159 m (522 ft) at that time. Its ground shape was in the form of a three-pointed star whose branches were separated each by a 120° angle.
