Ancient 'rusty treasure' emerges from river with enough iron to forge 500 swords

Key Points:

• Archaeologists in Austria have uncovered Europe’s largest known collection of Iron Age iron bars, with at least 500 bars weighing over a metric ton, likely lost in a Danube River shipwreck more than 2,000 years ago.
• The iron bars, dating to the 3rd or 2nd century B.C., may have originated from Bavaria and were possibly intended for forging weapons or tools, highlighting the scale of ancient iron production and trade.
• The discovery was made during gravel extraction in Deinham, Austria, and was preserved thanks to workers reporting it to authorities instead of selling the bars as scrap.
• Researchers believe the iron bars were transported via the Danube River and no signs of ritual destruction were found, supporting the shipwreck theory despite no vessel remains being recovered.
• This find significantly expands understanding of Late Iron Age iron production capacities and trade in the Danube region, with the quantity of iron being about ten times larger than other known hoards from the period.
