The waters of the ancient Portus Julius, the current town of Baia, hide a fascinating underwater world. 

In Roman times, Baia was the favourite holiday resort of the ancient Romans, where they went to benefit from the hot thermal springs. Here there were villas overlooking the sea, temples and thermal parks , which due to the phenomenon of bradyseism went completely submerged. 

The sea has perfectly preserved this immense archaeological heritage, which we will visit together during this unforgettable experience.
