During the international conference on safety issues of rescue operations in underground structures, held in Rome (Italy) on march 3rd, 2011, the argument of visitors’s safety of secret wartime tunnels in Dover has been discussed.
The presentation, made by Mr Steve Emery (English Heritage) has focused the attention on how fire safety engineering can be used to improve safety in historical buildings. In particular, the premise are underground. The first tunnels under Dover Castle were constructed in the Middle Ages to provide a protected line of communication for the soldiers. During the Napoleonic Wars, this system of tunnels was expanded to fortify the Castle. Seven tunnels were dug as barracks for the soldiers and officers. These were capable of accommodating up to 2,000 troops.
In May 1940 the tunnels became the nerve centre for ‘Operation Dynamo’ – the evacuation of the British Expeditionary Force (BEF) and French troops from Dunkirk’s beaches. In the Cold War the tunnels were further expanded to form a Regional Centre of Government in the event of nuclear war.
The presentation, taken from the Conference proceedings, shows how fire simulations have guided in developing a correct safety management for visitors:
