Boulevard Périphérique
Additionally, to south of the Boulevard Périphérique is a small section of the 15th arrondissement that was formerly a parade ground and then an airfield (at the beginning of the 20th century), but which is now occupied by the Paris - Issy-les-Moulineaux heliport, a sports complex (the Parc omnisport Suzanne-Lenglen), a recreational center (Aquaboulevard) and a small housing community called Les Frères-Voisin.
