Dover’s history, because of its proximity to France, has always been of great strategic importance to Britain.
Archaeological finds have shown that there were Stone Age people in the area; and that by the Bronze Age the maritime influence was already strong. Some Iron Age finds exist also, but the coming of the Romans made Dover part of their communications network. Dover was connected by road to Canterbury and Watling Street; and it became Portus Dubris, a fortified port. Forts were built above the port; lighthouses were constructed to guide passing ships; and one of the best-preserved Roman villas in Britain is here.
Dover figured largely in the Domesday Book as an important borough. Lots of the medieval buildings are still in use, such as the Maison Dieu (1203).
The town served as a bastion against various attackers: notably the French during the Napoleonic Wars; and against Germany during the Second World War. It was one of the Cinque Ports during medieval times.
