CANN TUNNEL, LEIGHAM: A WORLD WAR II DORMITORY AIR RAID SHELTER

THIS WAS TO BE USED AS AN UNDERGROUND SECURE BOMB PROOF ACCOMMODATION FOR DOCKYARD WORKERS IF/WHEN THE GERMAN AIR RAIDS ON PLYMOUTH HAD GOT SO BAD AND INTENSE THAT THERE WAS NO WHERE LEFT TO LIVE AT ALL. THERE WAS A BUS STOP AT THE SHELTER ENTRANCE TO GET WORKERS INTO THE YARD. THANKFULLY THIS DID NOT HAPPEN AND THERE WAS TALK OF IT BECOMING AN UNDERGROUND HOSPITAL. 

AFTER THE WAR IT BECAME A ROYAL  NAVAL DEPTH CHARGE STORE.
