More closely resembling a French château than a government building, the 19th-century Eisenhower Executive Office Building offers an aesthetic departure from Washington DC’s neoclassical government headquarters. Located right next to the White House’s West Wing, the building has gone through several evolutions; today, in addition to containing offices for White House staff, it is also home to the Vice President's Ceremonial Office (as well as a basement bowling alley installed by President Truman). In 1969, it was designated a National Historic Landmark.
The Eisenhower Executive Office Building is currently closed for public tours. However, its exterior can be admired during a range of Washington DC sightseeing itineraries, including driving, architecture, and walking tours.
