An emblematic center inaugurated in 1958 by General de Gaulle, the CNIT is an architectural jewel designed by Robert Camelot, Jean de Mailly, and Bernard Zehrfuss. This engineering feat features the largest unsupported concrete vault in the world, spanning 22,500 m² and reaching a height of 46 meters. Now transformed into a multifunctional complex, it houses shops, restaurants, a hotel, and office spaces.
