This edifice was the State, War and Navy Building when it opened along Pennsylvania Avenue in 1888. Once called America’s ugliest building by Mark Twain, the former Executive Office Building is now considered a U. S. National Historic Landmark. In 1999, it was renamed the Dwight D. Eisenhower Executive Office Building. The EEOB houses the Executive Office of the President, the Office of the Vice President and the National Security Council.
