Diving in Baia, in the Campi Flegrei Park, is a true discovery of a historical world. The Phlegraean Fields area is linked to the volcanic phenomenon of bradyseism, which is a periodic lowering and raising of the ground level.n particular. The most macroscopic phenomenon occurred on September 28, 1538, when the sea suddenly receded about 370 meters.
This coastal area north of Naples in the first century B.C. became a thriving health resort, thanks in part to the presence of the imperial villa Pausilypon (which gave Posillipo its name). Compared to the imperial era, the coastline has sunk by 6 to 8 meters. This makes it so that in order to admire the villa (and the nymphaeum of Punta Epitaffio) you have to take part in a dive!
The Baia Underwater Park was a recent discovery, dating back only to 1940. The first scientific dives were conducted in 1969, and only since 2002 has the underwater archaeological area been protected by law.
The nymphaeum at Punta Epitaffio housed some wonderful statues, most notably those of Ulysses and Dionysus. Now the original statues have been transferred to the nearby Archaeological Museum of the Phlegraean Fields: copies faithful to the originals can be seen during the dive.
During the dive, it is also possible to admire mosaics, frescoes and the ancient road layouts: thus, it is a kind of Roman Atlantis!
