From an Iron Plantation to presidential homes and an Old West trading post to a Cold War missile site, national historical sites offer visitors a new experience and a history lesson all in one. At historic sites across America, RVers and other travelers can enter into a different time, worldview, and social status with nothing more than a national park pass.

National Historic Site (NHS) is a designation for an officially recognized area of national historic significance in the United States. An NHS usually contains a single historical feature directly associated with its subject. A related but separate designation, the National Historical Park (NHP) is an area that generally extends beyond single properties or buildings and its resources include a mix of historic and later structures and sometimes significant natural features.
There are currently 89 NHSs and 58 NHPs. Most NHPs and NHSs are managed by the National Park Service (NPS). Some federally designated sites are owned by local authorities or privately owned but are authorized to request assistance from the NPS as affiliated areas.

All historic areas including NHPs and NHSs in the NPS are automatically listed on the National Register of Historic Places (NRHP). There are also about 90,000 NRHP sites, the large majority of which are neither owned nor managed by the NPS. Of these, about 2,500 have been designated at the highest status as National Historic Landmark (NHL) sites.
