The history of Washington, D.C., is tied to its role as the capital of the United States. Originally inhabited by an Algonquian-speaking people known as the Nacotchtank, the site of the District of Columbia along the Potomac River was first selected by President George Washington. The city came under attack during the War of 1812 in an episode known as the Burning of Washington. Upon the government's return to the capital, it had to manage reconstruction of numerous public buildings, including the White House and the United States Capitol. The McMillan Plan of 1901 helped restore and beautify the downtown core area, including establishing the National Mall, along with numerous monuments and museums.
This is a list of properties and districts in the District of Columbia on the National Register of Historic Places. There are more than 600 listings, including 74 National Historic Landmarks of the United States and another 13 places otherwise designated as historic sites of national importance by Congress or the President.
