Overview
- A study published Sunday in the journal Antiquity reports that workers first alerted authorities in 2019 after gravel extraction in Deinham revealed hundreds of double‑pointed iron bars now counted as at least 500 fragments weighing about one metric ton.
- Researchers have dated the assemblage to the La Tène or Late Iron Age (3rd–2nd centuries BCE) and identified the objects as semifinished bipyramidal bars roughly 28.5 cm long and 1.6–2.4 kg each.
- The team estimates the haul could have yielded about 500 swords or up to 8,000 nails, showing these bars functioned as transportable trade units rather than finished tools or weapons.
- Industrial gravel extraction in 2019 destroyed the original riverbed context, which prevents direct archaeological proof of how the bars entered the Danube and limits conclusions about shipwreck versus ritual deposition.
- Ongoing elemental and trace analyses aim to test a likely Bavarian or Manching-area source and to clarify Late Iron Age production and river trade networks in central Europe.
