Ancient Britons extracted salt from seawater more than 5500 years ago
Stone Age Britons extracted salt from seawater using industrial-style processes more than 5500 years ago. The discovery means people in Great Britain were producing salt thousands of years earlier than thought, before the Bronze Age.
The technology may have been brought by migrants arriving from mainland Europe.
“It changes how we think about Neolithic society,” says Stephen Sherlock, an independent archaeologist based in Redcar, UK.
