The Eisenhower Executive Office Building (EEOB), formerly known as the Old Executive Office Building (OEOB), and originally known as the State, War, and Navy Building (SWAN Building), is a United States government building that is now part of the White House compound in the U.S. capital of Washington, D.C. The building houses various agencies that comprise the Executive Office of the President, such as the White House Office, the Office of the Vice President, the Office of Management and Budget, and the National Security Council.^[3] Opened in 1888, the building was renamed in 1999 in honor of Dwight D. Eisenhower, the 34th U.S. president and a five-star U.S. Army general who was Allied forces commander during World War II.

The building is located on 17th Street NW, between Pennsylvania Avenue and State Place and West Executive Drive. It was commissioned by President Ulysses S. Grant, and built between 1871 and 1888 on the site of the original 1800 War/State/Navy Building^[4] and the White House stables, in the French Second Empire style.

As its original name suggests, it was initially built to house the staff of three government cabinet departments. The building's elaborate architectural style received substantial criticism when it was first completed; it has since been designated as a National Historic Landmark.
