Free audio guide app offers a geolocated audio guide for the Fontana dei Quattro Fiumi in Piazza Navona, letting you follow Bernini's Baroque figures and the Agonal Obelisk as you circle the basin. The narration highlights the four river allegories — the veiled Nile and the silver Río de la Plata — and layers ambient sound to enrich the walk. Brief notes mention its papal commission and civic role in the square. Voiced narration and ambient water textures create an immersive stroll.
