The existence of the ancient sunken city of Buca, mentioned by classical authors such as Pliny the Elder, remains a mystery for archaeologists. The city is believed to have been located near Termoli or Petacciato, along the Molise coast. Over there, several underwater findings suggest the presence of a sunken settlement. In 1989, in the area of L’Aspro—a rocky outcrop about 4 km south of Petacciato—important artifacts such as amphorae and an anchor were recovered, confirming the area’s ancient past.
Between the waters off Petacciato and Termoli lies the legendary sunken city of Buca, an ancient Roman port that continues to fascinate historians and divers alike. Shrouded in mystery, Buca may have been swallowed by the sea following landslides or earthquakes. Today, its ruins rest silently on the seabed, drawing explorers and travelers eager to dive into history and experience a one-of-a-kind adventure.

Diving enthusiasts can explore what are believed to be the sunken remains of Buca, located at a depth of around 10 meters. Even if you’re not an experienced diver, the crystal-clear waters of the Molise coast offer spectacular views for those who simply wish to snorkel and observe the seabed from above.
Over the years, explorations and studies by researchers such as Luigi Marino and Filippo Di Donato have revealed masonry structures and Roman-era materials, suggesting that Buca was once a significant harbor settlement. Some theories propose that seismic activity or a massive landslide led to its submersion. In addition, recent research continues to shed light on its possible location, strengthening the hypothesis that Buca may lie near the Torre di Petacciato, a site rich in archaeological remains.
