Dover Castle

Dover Castle is a medieval castle in Dover, Kent. It was founded in the 11th century and has been described as the 'Key to England' due to its defensive significance throughout history. It is also the largest castle and the oldest fort in England. Originally strengthened from an Anglo-Saxon fort in 1066 by William the Conqueror with further additions made by Henry II and Henry VIII, it has endured many battles. Visitors can discover the labyrinth of secret wartime tunnels built under Dover's white cliffs and walk through the rooms where the Dunkirk evacuation was planned.
