Dover is a major channel port in the English county of Kent.
At the 2001 census, the town of Dover proper had a population of 28,156 inhabitants, while the population of the whole urban area of Dover, as calculated by the Office for National Statistics, was 39,078 inhabitants.
Dover is famous for its white cliffs, which are made of chalk.
The white cliffs of Dover, immortalized in popular song and verse (by Vera Lynn, Kate Smith, Matthew Arnold, Eric Johnson and others), are cliffs facing the Strait of Dover near the major English port town of Dover, in the county of Kent, and form part of the North Downs.
The cliff face continues to erode at an average rate of one centimetre per year, although occasionally—most recently in 2001—large chunks of the edge, up to several metres at once, will fall into the channel with little warning.
Behind the cliff face are miles of hidden tunnels that were created during the Middle Ages and later played a role in the defense of Britain during the Napoleonic Wars.
