Early access tours, exclusively for groups, have been introduced by English Heritage deep inside the Secret Wartime Tunnels at Dover Castle.
Groups can now also enjoy private guided tours of King Henry II’s technicolour Great Tower.
Operation Dynamo Tunnel Tours takes visitors on an experience in the Secret Wartime Tunnels.
Running beneath the White Cliffs, they housed the nerve-centre of operations for Winston Churchill and Vice Admiral Ramsay as they masterminded the evacuation of troops from Dunkirk in 1940.
Great Tower Tours take in King Henry II’s magnificent 12th-century palace, standing at the heart of Dover Castle.
Visitors today will be equally impressed by the recreation of the king’s colourful display of wealth, as expert guides lead them through the private chambers, guest rooms, kitchen, armouries and great hall.
