The tower was built in 1974 by Bouygues for the UAP insurance company.
Its ground shape was in the form of a three-pointed star whose branches were separated each by a 120° angle.
This particular shape was chosen to symbolize the merger of the three French insurance companies that were at the origin of UAP.
The exterior appearance of the building was completely changed, with extra height added to the tower.
It is currently the tallest skyscraper in France, only surpassed in height by the Eiffel Tower.
