The discovery is 15 kilometers from Naples, in Italy’s Campania region. Builders working on a children’s playground and recreation area were the first to stumble on the ruins of an imposing residence. Archaeologists then arrived to study the remains and draw initial conclusions.

What the Archaeologists Found
The panoramic villa, which overlooks the islands of Ischia and Procida, is now partially submerged in the sea. Experts think it could have been the 1st-century AD seaside residence of Pliny the Elder, the naturalist and commander of the Roman fleet.
Researchers uncovered thick stone walls, the remains of ten large rooms with surviving floor surfaces, tiled wall fragments, and a maze of open panoramic terraces.
CNN reported that more than two thousand years ago the villa stood within the territory of the Roman port of Misenum. For four centuries, the local fleet of 70 ships controlled the Tyrrhenian Sea, protecting the western flank of the Roman Empire.
The villa’s windows likely offered a 360-degree view of the Bay of Naples, which would have been crucial for military surveillance, said Italian archaeologist Simona Formola. She expects that digging deeper will uncover more rooms and possibly frescoes.
The team was impressed by the walls’ intricate construction: diamond-shaped tuff blocks arranged in a mesh pattern.

Near the villa sits a small, partially ruined stone dock submerged about four meters below sea level. It’s common for coastal structures in volcanic regions to end up underwater.
Archaeologists say the villa served both as a lookout and a leisure retreat, where the owner would welcome noble guests arriving by sea for lavish parties. In that era, many Romans flocked to Bacoli to relax in seaside villas and take the baths.
Bacoli sits in the Phlegraean Fields, or “Fiery Plains,” an area dotted with geysers and small active craters that remains geologically unstable. Pliny the Elder may have been at this villa when Mount Vesuvius erupted in 79 AD; he died while trying to rescue people from the eruption.
What’s Next?
Archaeologists were excited, but locals had long suspected buried ruins in the area. On the beach near the villa walls lie other brick remains, suggesting the site may be part of a larger complex of ancient residences.
During excavations that will continue in the coming months, regional authorities hope to clarify not only the layout and purpose of the beach villa but also the history of Misenum, one of the Roman Empire’s most important ports. “This discovery is exceptional considering how little we know about the port of Misenum,” Formola said.
In the coming weeks, the site will become an open-air museum. “The ruins of the Roman villa will be cleaned and surrounded by wooden fences,” the city hall of Bacoli announced.
