Free audio guide app offers a dedicated, location-based listening experience for the Grand Palais: Discovery Mode triggers geolocated audio narrations as you walk around its Belle Époque façade and monumental glass roof, highlighting 1900 Universal Exhibition origins and civic role. Rich narration and archival sounds bring exterior viewpoints to life. Tour Mode supplies thematic routes and gamification—points and digital souvenirs—as you circle the building along avenue Winston-Churchill.
