Folkestone is a coastal town on the English Channel, in Kent, south-east England. The town lies on the southern edge of the North Downs at a valley between two cliffs. It was an important harbour, shipping port, and fashionable coastal resort for most of the 19th and mid-20th centuries. This location has had a settlement since the Mesolithic era. A nunnery was founded by Eanswith, granddaughter of Æthelberht of Kent in the 7th century, who is still commemorated as part of the town's culture.
