A family watch as desperate troops try to escape from enemy fire


Imagine working day and night deep inside Dover Castle's top secret tunnels as war raged outside, in a desperate bid to rescue the troops stranded at Dunkirk as German forces closed in.

This gripping battle against time was won in just ten short days in 1940, when Vice Admiral Bertram Ramsay pulled off a miracle. With no technology and with pitiful resources he masterminded the rescue of 338,000 troops from his Naval HQ in the tunnels below the castle.

Operation Dynamo: Rescue from Dunkirk uses original news-reels and recordings, testimonies from veterans and dramatic special effects to recreate the terror and tension of these dark days of Second World War.


The urgency and drama unfolds in self guided tours that take visitors in small groups through the tunnel casemates. It was here that Ramsay plotted and planned his brilliant operation, issuing the orders and making the decisions that saved so many lives. The tours are 'pulsed' so that visitors have the space to fully appreciate this immersive experience.

As Spitfires screech overhead and the boom, boom of anti-aircraft guns resonates, visitors relive the danger and desperation in the cramped tunnels.  Vivid sets and original film give a graphic account of the horror of the French beaches under fierce enemy fire. 

This gripping experience also pays tribute to Vice Admiral Ramsay, the unsung hero whose brilliant organisational skills pulled off the greatest rescue in our history.

An unmissable part of every day out at Dover Castle the tour continues through some of the original rooms of the adjacent Army HQ. Dressed as they were throughout Second World War, they include the Gun Operations Room, Telephone Exchange, Repeater Station (communications room) and Coast Artillery Operations Room.

Operation Dynamo: Rescue from Dunkirk is a permanent new visitor experience within the Secret Wartime Tunnels at the castle.
