Ancient cargo found in river may have come from lost shipwreck

Gravel workers in Austria uncovered a massive collection of ancient iron bars containing enough metal to forge roughly 500 swords. Archaeologists believe the 2,000-year-old treasure may have ended up in the Danube River following a shipwreck.

Archaeologists have identified Europe's largest known collection of Iron Age iron bars after workers discovered the ancient treasure during gravel extraction in Austria. Weighing more than a metric ton, the valuable cargo may have been lost in a shipwreck more than 2,000 years ago.
