DC is home to several iconic landmarks, including the White House where the U.S. president resides, the Capitol building that houses the meeting chambers of the Senate and the House of Representatives, and the National Mall, where you can stop by the Lincoln Memorial, the Washington Monument, and the World War II Memorial. One of the reasons Washington, DC is among the best destinations to visit with your family is because it is home to so many world-famous museums, including the Smithsonians – 16 museums scattered across the District, most of which are open every day of the week, and even better, every single one is free.
