Divers in a Swiss lake discovered a 2,000-year-old Roman shipwreck filled with remarkably well-preserved artifacts, including Gladius swords, olive oil amphorae, ceramics, tools, and wagon wheels.

The wreck, found in Lake Neuchâtel, dates to between 20 and 50 AD and is believed to have been part of a Roman merchant vessel.

Archaeologists noted the unusual clustering of the cargo and the exceptional preservation of the items.

The presence of military weapons suggests the ship may have had an escort to protect against piracy, the New York Post has reported.

The recovered artifacts are being conserved and studied to better understand ancient Roman trade routes and will eventually be displayed in a museum.
