Baiae

description Baiae Overview

Baiae was an ancient Roman settlement and leisure resort on the Gulf of Naples in Italy, known for thermal springs, villas, and buildings associated with elite recreation. Geological subsidence and bradyseism caused parts of the coastal town to sink beneath the sea, preserving submerged streets, walls, mosaics, and architectural remains. These ruins are protected and studied within the Underwater Archaeological Park of Baiae.

help Baiae FAQ

Where was the Roman resort of Baiae located?

Baiae stood on the Gulf of Naples near the modern town of Bacoli in southern Italy. It was a luxury coastal resort frequented by wealthy Romans.

Why are parts of Baiae underwater today?

Volcanic activity in the Campi Flegrei area caused gradual changes in the land level, lowering parts of the ancient coastline. As a result, villas, mosaics, roads, and columns now lie beneath the sea.

Can visitors dive at the submerged ruins of Baiae?

The underwater ruins are protected within an archaeological park and can be explored through authorized diving and guided underwater activities. The site is managed as a cultural heritage area rather than an unrestricted dive location.

What remains can be seen at underwater Baiae?

The submerged area preserves Roman architectural remains such as villa walls, pavements, mosaics, and columns. These features show why Baiae was more than a beach resort: it was a built Roman settlement for elite leisure.
