The White House ties with Elm Court at #30, but this world-famous mansion certainly deserves its own spot. The White House is the official residence for the United States President and their family, and people come from all over the world just to see it.
The presidential palace sprawls across 55,000-square feet. While rebuilt and renovated several times, the White House we know today consists of several wings, offices, guest suites, and even a two-story basement. The home is maintained by the National Heritage Site and National Park Service staff, making sure its iconic look stays.
