A team of archaeologists from the University of Exeter has found a Roman fort dating from the 1st Century AD in fields in Cornwall.
Several items of pottery have been excavated and a furnace which may have been used to smelt minerals.
Researchers said the find at Calstock, close to a silver mine, could show for the first time the Romans’ interest in exploiting Cornish minerals.
The way they found it is worth reading. Neat bit of detective work followed by some remote sensing.
