Free audio guide app offers geolocated audio guides (Discovery Mode) with a dedicated narration for the Archi di Porta Nuova, triggering as you walk to highlight its role as a medieval city gate and the marble tabernacle of the Madonna and Child with Saints. Thematic audio tours (Tour Mode) and subtle gamification with points and digital souvenirs enrich the listening experience.
