Dover
No fortification in the British Isles has a longer recorded history than Dover castle, and the town on its doorstep shares its antiquity. Dover’s prosperity was firmly based on its position as the main port of embarkation for travellers to the continent. It suffered for a time in Edward III’s early French wars, owing to the absence of a secure port of landing on the other side of the Channel, but the capture of Calais remedied this lack, though it also provided a rival for control of the crossing.
