Parco Sommerso di Baia

Parco Sommerso di Baia is one of the world's most extraordinary dive sites — a submerged Roman city in the Gulf of Pozzuoli, sunk by volcanic bradyseism over centuries. Divers glide over ancient mosaic floors, marble columns, thermal bath complexes, and statuary resting 5 to 15 meters below the surface. This underwater archaeological park is strictly protected, with guided dives revealing remnants of the Roman elite's luxury resort town. An unparalleled fusion of history and diving that transports you directly into the ancient world.
