Free audio guide app presents a dedicated geolocated audio guide for Avenue de la Grande Armée, designed so each commentary triggers as you reach key viewpoints along the 775 m ceremonial axis toward La Défense. Narration highlights the avenue’s urban role and recent pedestrian redesign, with ambient soundscapes and cues timed to the view. Optional gamification awards digital souvenirs for listening spots, with short tracks suited to a walking visit.
