7. Secret Tunnels and Escape Routes
During World War II, President Franklin D. Roosevelt authorized the construction of an underground passage connecting the White House East Wing to the Treasury Building. This 761-foot-long tunnel, designed in a zigzag pattern to mitigate blast damage, was intended to provide a secure evacuation route for the president during emergencies. Equipped with small rooms that once contained cots, the tunnel served as a shelter and a means of discreet movement between the two buildings. Additionally, beneath the East Wing lies the Presidential Emergency Operations Center (PEOC), a fortified facility built to protect the president and key staff during crises. These subterranean structures reflect the evolution of national security measures and the White House’s preparedness for unforeseen events. (whitehousehistory.org)
