Free audio guide app offers geolocated audio guides that turn a walk along Boulevard du Palais into a narrated, on-site experience. The dedicated audio focuses on the street’s judicial role and the Conciergerie towers, pairing brief historical cues, ambient soundscapes and the hushed local legend of the notary’s ghost to enrich what you hear as you stroll. The guide synchronizes to your position for paced, place-based listening. Voices and ambient recordings enhance on-site presence.
