Stefano D'Urso / Centro Sub Campi Flegrei

Parco Archaeologico Sommerso di Baia, Pozzuoli, Italy

Pompeii doesn’t have the lock on ancient Italian trauma. Thanks to bradyseism—the gradual raising or lowering of earth due to filling magma chambers—the neighborhood of Baia, 30 minutes west of Naples, now rests in about five to 15 feet of water. Guided tours for both snorkelers and divers cover eight underwater (and four terrestrial) sites like Villa Protiro and Portus Julius. Intricate black-and-white mosaic floors, loose statues, and frescoes mingle with sea stars and anemone shoals...for now. As recently as 1984, the sea floor raised six feet.
