Folkestone is the principal town in the Shepway District of Kent, England. Its original site was in a valley in the sea cliffs and it developed through fishing and its closeness to the Continent as a landing place and trading port. The coming of the railways, the building of a ferry port, and its growing importance as a seaside resort made the town grow. However, business has declined. The beginning of high speed rail services for commuters on the HS1 line to London St Pancras has cut the journey time from London to less than an hour. Folkestone now has the only sandy beach [“Sunny Sands”] and coastal park within an hour of north London.Although Kent was the first part of the British mainland to be conquered and settled by the invading Angles, Saxons and Jutes from the middle of the 5th century AD onwards, after the departure of the Romans, it was not until the late 7th century that the spelling Folcanstan appears.
