The history of Folkestone stretches back to ancient times, with evidence of human habitation dating to the Mesolithic and Paleolithic ages over 12,000 years ago. Its close proximity to the Continent means that it has often been a point of transit for migrating peoples. The area has successively been occupied by groups of Britons, Romans and Saxons. During the Iron Age, a large oppidum and quern-stone workshop were situated on the eastern headlands of the bay. By the Roman era, it had been transformed into a large Roman Villa overlooking the sea.
