A three and one half mile network of tunnels was built
beneath the castle and into the white cliffs prior to World War II. Sir
Winston Churchill and Admiral Ramsey planned the evacuation of Dunkirk from these
tunnels. The tunnels include an underground hospital which was used
for RAF pilots who were shot down during the Battle of Britain.
The "Secret Wartime Tunnels" remained secret throughout the
cold war as the British Government intended to used them for regional
government in event of nuclear war. The tunnels are now open to the
public.
