White House to Treasury Building tunnel

The tunnel connects the East Wing basement of the White House to the Treasury Building following a zig-zag pattern designed for protection. Inside, modern security systems include cameras, alarms, and specialized locks throughout the passage.

Construction began in 1941 following the Pearl Harbor attack to create a secure escape route. The project was part of early wartime measures to strengthen government protection.

The passage shows how government buildings were designed during wartime to keep daily work running without interruption. Its construction reflects technical advances that combined security needs with practical government operations.

The tunnel is not open to the public, but may be briefly mentioned or partially visible during certain official tours. Visitors should contact the White House visitor center for information about any possible viewing opportunities.

Before official bunker facilities were finished, a presidential suite with hotel-grade accommodations was prepared inside the Treasury Building. This provisional shelter was meant to provide a safe place while other protective installations were still under construction.
