Dover is a town and major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel at 33 kilometres (21 mi) from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Port of Dover.

The confederation of Cinque Ports is a historic group of coastal towns in south-east England – predominantly in Kent and Sussex, with one outlier (Brightlingsea) in Essex. The name is Old French, meaning "five harbours", and alludes to the original five members. At its peak in the Late Middle Ages, the confederation included over 40 members. There are now a total of 14 members: five "head ports", two "ancient towns" and seven "limbs".
