Overview
The Parco Sommerso di Baia is a unique Marine Protected Area located in the Phlegraean Fields, near the city of Pozzuoli in the Campania region of Italy. Recognized under the designation EUAP0849, this submerged archaeological park preserves the ancient Roman city of Baia, which was once a luxurious seaside resort for the Roman elite. Due to the geological phenomenon of bradyseism—the gradual uplift and subsidence of the Earth's crust—significant portions of the ancient coastline, including imperial villas, thermal baths, and mosaic floors, now lie beneath the surface of the Tyrrhenian Sea. Visitors to this extraordinary site can explore these ruins through glass-bottom boats, snorkeling, or scuba diving, offering a rare opportunity to witness history preserved in a marine environment. The park serves as a vital center for underwater archaeology and marine conservation, attracting researchers and tourists alike. When considering trip ideas for coastal exploration, the Parco Sommerso di Baia stands out as a premier destination for those interested in the intersection of Roman history and marine science. As one of the most significant underwater sites in the Mediterranean, it represents a fascinating case study in how natural geological processes have shaped human history. For travelers planning their itinerary, checking local attractions in the Phlegraean Fields will reveal the depth of historical layers present in this volcanic landscape, making it an essential stop for any history enthusiast or diver.

- The park spans approximately 176 hectares of protected marine environment.
History
Baia was a thriving Roman resort town renowned for its thermal springs and opulent villas. During the late Roman Republic and the early Empire, it served as a retreat for the aristocracy, including figures such as Cicero and Hadrian. However, the town's proximity to the volatile volcanic activity of the Phlegraean Fields led to its gradual decline. Over centuries, the land subsided due to bradyseism, causing large sections of the coastal infrastructure to sink into the sea. By the 8th century, the site was largely abandoned. It was not until the 20th century that systematic underwater archaeological investigations revealed the extent of the submerged ruins, leading to the formal establishment of the protected marine park to preserve the site's immense historical value.
Cultural significance
The Parco Sommerso di Baia is a site of profound archaeological importance, acting as a submerged museum that documents the architectural and social life of Roman nobility. It provides scholars with an unparalleled view of ancient construction techniques, urban planning, and domestic luxury. Culturally, the park bridges the gap between terrestrial history and marine biology, showcasing how human civilization and the natural world interact over geological timescales. It is a protected site that promotes the preservation of cultural heritage, ensuring that these fragile underwater mosaics and structures are maintained for future generations while providing a unique educational experience that highlights the vulnerability of coastal cities to environmental change.
Geography and landscape
The park is situated within the Gulf of Pozzuoli in the Tyrrhenian Sea, part of the larger Phlegraean Fields volcanic area. The landscape is defined by its complex geological history, characterized by volcanic craters and geothermal activity. Underwater, the terrain features a mix of rocky outcrops, sandy sea floors, and the remnants of Roman walls, columns, and paved roads that have been colonized by marine flora and fauna. The water depth varies, allowing for different types of exploration, from shallow snorkeling over mosaic-covered floors to deeper dives among the submerged harbor structures. The surrounding coastal area remains a mix of modern urban development and historical sites, set against the backdrop of the volcanic hills of the Campania region.
