A rediscovered World War 2 plotting room hidden under an iconic British landmark is set to open to visitors for the first time, the National Trust has revealed. Built in 1940, the Fan Bay Plotting Room was a war operations centre that helped direct guns defending the Strait of Dover, Britain’s front line, following the fall of France. Hidden beneath its guns and deep in the white cliffs of Dover, the plotting room was home to some of the most advanced military technology of its time, such as the fire direction table, to calculate firing data and co-ordinate artillery operations.
