Scientists have determined that fragments of artifacts recovered from the Broxmouth Iron Age hill fort in the 1970s were forged from high-carbon steel. The objects, which date to between 490 and 375 B.C., may have been tools or weapons. “The process of manufacturing steel requires extensive knowledge, skill and craftsmanship. It is far from straightforward, which is why such an early example of its production tells us so much about the people who once occupied this hill fort,” said Gerry McDonnell of the University of Bradford. The site featured well-preserved roundhouses, hill fort entrances, and an Iron Age cemetery.
