History
Baia was an elite Roman resort; periodic bradyseism and volcanic activity lowered land levels, submerging parts of the town and preserving features underwater.
Conservation
The area is a protected marine park — guided visits, no-touch rules, and regulated access help preserve both archaeological remains and Posidonia seagrass beds.
