Archaeologists discover a 3,300-year-old sword at the bottom of a volcanic lake in Italy - and it's still sharp

Published: 07:36 EST, 9 November 2026 | Updated: 07:36 EST, 9 November 2026 A remarkably well-preserved Bronze Age sword has been found at the bottom of a lake, where it has lain undisturbed for more than 3,000 years.The weapon, which dates to around 1300 BC, was found during an underwater excavation at Lake Mezzano, a small volcanic lake in central Italy.Despite spending millennia underwater, the impressive blade is still exceptionally sharp.Experts believe the sword may have been deliberately deposited as part of a ritual offering, a practice already linked to several Bronze Age European sites.The discovery was announced by Italy's Superintendence of Archaeology, Fine Arts and Landscape for the Province of Viterbo and Southern Etruria.It said: 'The artefact, preserved in excellent condition, still featuring a sharp edge, represents an important addition to our understanding of the communities that frequented the lake basin over three thousand years ago.'Due to its typological and chronological characteristics, the sword fits perfectly within the framework of central Italian weaponry production in the Late Bronze Age, demonstrating the level of metallurgical specialization achieved by the communities of the time.' A researcher exploring Lake Mezzano holds up the weapon, which dates back to around 1300 BC Despite spending millennia underwater, the impressive blade is in remarkably good condition and is still exceptionally sharpThe sword is the third to be found at the site in the past 50 years, reinforcing the area's reputation as an archaeological treasure trove.Experts believe the lake once contained a thriving Bronze Age village built on wooden stilts above the water.Known as a pile-dwelling settlement, residents here would have been protected from flooding and had easy access to fishing.The latest dig also unearthed intact pottery and a hoard of bronze objects, including axes, daggers, spearheads and a razor.Experts were particularly struck by the sword's location next to a bronze razor, as such pairings have been found in the graves and possessions of elite Bronze Age warriors elsewhere in Europe.'In this context, bronze weapons were not only instruments of combat, but also symbols of prestige, identity, and power,' they said.

It's possible the weapon may have been deliberately placed in the lake as part of a wider Bronze Age ritual, during which valuable objects such as jewellery, weapons and other prized possessions were offered to the water.Similar practices continued for centuries, with later Etruscan communities depositing artefacts, and sometimes even human remains, in wells and other sacred sites as part of religious ceremonies.
