[The Guardian] Iron Age Britons were importing olives from the Mediterranean a century before the Romans arrived with their exotic tastes in food, say archaeologists who have discovered a single olive stone from an excavation of an Iron Age well at at Silchester in Hampshire. The stone came from a layer securely dated to the first century BC, making it the earliest ever found in Britain – but since nobody ever went to the trouble of importing one olive, there must be more, rotted beyond recognition or still buried.
