Danube Iron Hoard Reveals Late Iron Age Trade: 500 Bars Found

Archaeologists analyzed 500 semifinished iron bars recovered from a Danube gravel pit near Deinham, Austria, dating to the 3rd–2nd centuries BC. The find includes 193 complete bars and 307 fragments, weighing about a metric ton, enough material to forge roughly 500 swords or 8,000 nails. The bars were likely intermediate ingots rather than finished weapons, underscoring substantial iron production and trade in the Late Iron Age along the Danube. The original context was destroyed by gravel extraction, but the discovery marks Europe’s largest cache of prehistoric iron and may trace its origin to Bavaria.
