U.S. Department of State - Washington, D.C.
The Harry S. Truman Building serves as the U.S. Department of State’s Headquarters in Washington, D.C. It was originally built to house the War Department, which had outgrown the building before it was ever completed and therefore needed a new space, the Pentagon. The Foggy Bottom building became the home of the State Department in the late 1940s, was expanded in 1961, and has undergone several renovations and modernizations since that time. In 2022 the new D Street “employee” entrance opened. More than 2,000 people enter through this entrance daily.
