A maze of tunnels and secret chambers, mainly extended during Napoleonic times and the Second World War, have been created beneath this castle. They were used a command post during Operation Dynamo in 1940. A guided tour of the Secret Wartime Tunnels (chambers, underground hospital, communications centre etc), accompanied by sound effects and other installations, at times somewhat macabre, lend the site an almost Orwellian atmosphere.
