📍 About This Attraction
Beneath the azure waters of Vasto Marina lies one of Abruzzo’s most fascinating archaeological treasures – the Parco Archeologico Sommerso di Vasto Marina. This underwater archaeological park preserves remarkable Roman remains dating back approximately two thousand years, offering visitors a unique glimpse into the ancient maritime heritage of Histonium, the Roman settlement that once flourished where modern Vasto now stands.
Located along the scenic Lungomare Ernesto Cordella, this submerged site represents a rare opportunity to explore underwater archaeology along the Adriatic coast. The park contains numerous well-preserved Roman structures that were gradually claimed by the sea over centuries, creating an extraordinary underwater museum that tells the story of ancient coastal life in Abruzzo.
Since 2017, the Italia Nostra del Vastese section has spearheaded ongoing scientific research at the site, working in collaboration with the local Parsifal Cooperative Society. These dedicated organizations not only continue to uncover the secrets of ancient Histonium but also organize guided excursions that allow visitors to experience this underwater wonder firsthand.
For those seeking to connect with Vasto’s ancient past in a truly unique setting, the Parco Archeologico Sommerso offers an unforgettable journey through time. The combination of archaeological significance and the natural beauty of the Adriatic Sea makes this site a standout attraction along the Abruzzo coast.
