9. The Secret Tunnels
There are indeed secret tunnels underneath the White House. There is a bunker located approximately six stories underground underneath the East Wing. It is believed that there are trap doors inside the Oval Office that lead down into the secure bunker.
The only thing that is known for sure is that after Pearl Harbor, President Franklin D. Roosevelt did have a bomb shelter built and there was access to the vaulted basement of the Treasury Building directly from the White House. The room specifically for the President was basically just a concrete box. President Franklin D. Roosevelt only went to see it once. Several Presidents since Roosevelt have seen it, but just as a symbolic gesture, acknowledging the turbulent and challenging times of America’s great history.
