Along the southern shore of Lake Mezzano, in Italy’s Tuscia region north of Rome, divers lifted a bronze sword whose blade still holds a cutting edge after more than 3,000 years underwater. It is the third sword recovered from the lake since research began there in the 1970s, and it dates to the 13th century BCE, the Late Bronze Age.
The lake fills the crater of an ancient volcano, and beneath its surface lie the timbers of a village built on wooden piles. Archaeologists say the sword was found beside a bronze razor, in a stretch of shoreline that had been only marginally investigated before.
A Southern Shore Few Had Searched
The find came in the final phases of an underwater campaign run by the Underwater Archaeology Service of the Soprintendenza Archeologia, Belle Arti e Paesaggio for the province of Viterbo and Southern Etruria, the state heritage office led by Margherita Eichberg, according to the Italian art outlet Finestre sull’Arte. Carabinieri divers from Rome supported survey, documentation and safety, while underwater restorers from CSR Restauro Beni Culturali secured the sword during recovery and began conserving it. The municipality of Valentano collaborates on protecting the site.
The English-language Archaeology Magazine report describes the blade as in excellent condition, and the Italian travel site SiViaggia calls it perfectly preserved, noting an axe and several nearly intact vessels were recovered in the same area. Neither source gives a length or weight, and no individual archaeologist is quoted by name in the coverage; the claims rest on the Soprintendenza.
Conditions at the bottom are hard on divers. The Soprintendenza’s September 2025 announcement of the new campaign called reduced visibility one of the main difficulties, because diver movement stirs up sediment, and the team uses water clarifiers to keep the work site readable. Surface water was about 30 degrees Celsius, yet it dropped to roughly 14 degrees at the level of the remains, a steep gradient for anyone working there. Underwater archaeologist Barbara Barbaro directs the Underwater Archaeology Service, and CSR Restauro Beni Culturali, directed by Riccardo Mancinelli, handles restoration of what comes up.
The find was announced as the season closed.
Razor and Blade as a Warrior Pairing
A sword lying next to a razor carries meaning for specialists. Pairings of the two have been linked elsewhere in Bronze Age Europe to high-ranking individuals, probably warrior elites, though the Italian report presents that only as a possibility for Mezzano and not as a conclusion about who owned these objects.
Metal in European wetlands is also often read as deliberate offering, objects placed in water on purpose rather than lost. The report raises that question for Mezzano without answering it. Future underwater stratigraphic excavation is meant to record the exact positions of the finds, which is the evidence that could separate a ritual deposit from material that slid off a collapsing platform.
A Village Built on Piles, 1700 to 1150 BCE
The sword’s date is narrower than the village’s. According to the Soprintendenza’s own account of its 2025 campaign, the pile-dwelling settlement runs from the end of the Early Bronze Age to the Recent Bronze Age, roughly 1700 to 1150 BCE, and shifted with lake levels over about six centuries. That is why a 13th-century BCE sword belongs to a late chapter of a much longer occupation.
That earlier season mapped more than 600 piles in 2.5 to 10 meters of water, covering about a third of the known settlement. Crews removed compact clay with suction equipment in cold, murky conditions and recovered more than 25 bronze objects in excellent condition, among them winged axes, spearheads, fibulae, rings, a pin, a sickle and fragments of bronze ingots that suggest metalworking. A pierced stud with a solar motif was reported as unusual. Greek Reporter’s account of the same season adds that some objects show fire damage, consistent with burned timber structures falling into the lake.
Because the wooden piles and the metal lie in layers of clay and lava stone, the order in which objects sit matters as much as the objects. The Archaeology Magazine report observes that the depths of the metal pieces are notably consistent across different parts of the site, while the 2025 campaign found that some materials appear to have fallen or rolled from a wooden structure and that bronzes sat in areas with lava stones, possibly from ancient landslides. Collapse and landslide, as well as human choice, therefore shaped what the divers now find.
Digging Methods and a Planned Exhibition
The site’s modern research history is longer than most visitors would guess. Geologist Lamberto Ferri Ricchi first spotted wooden remains on the lake bottom in the winter of 1971, and the Soprintendenza’s September 2025 announcement says excavation campaigns began in 1973, with further cycles between 1983 and 1996 before a long pause. New funding under Law 190 restarted the work.
The southern-shore sword now adds to a list of finds that the Soprintendenza says will be shown in an exhibition devoted to the bronzes of Mezzano, though no opening date has been announced. Further digging will test whether the razor and sword were deposited together and how they relate to the depth bands already mapped.
