This is a complete List of National Historic Landmarks in Washington. The United States National Historic Landmark program is operated under the auspices of the National Park Service, and recognizes structures, districts, objects, and similar resources nationwide according to a list of criteria of national significance.[1] The state of Washington is home to 24 of these landmarks, extensively highlighting the state's maritime heritage (with eight individual boats) and contributions to the national park movement (including three sites within Mount Rainier National Park, which is also listed), while recognizing a range of other aspects of its historic legacy.
