National Historic Site (NHS) and National Historical Park (NHP) are designations for officially recognized areas of national historic significance in the United States. They are usually owned and managed by the federal government. An NHS usually contains a single historical feature directly associated with its subject, while an NHP is an area that generally extends beyond single properties or buildings to include a mix of historic and later structures and sometimes significant natural features.^[1]

As of 2024, there are 63 NHPs and 85 NHSs. 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.^[2] One property is managed by the U.S. Forest Service, Grey Towers National Historic Site.^[3]

As of October 15, 1966, 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^[4] have been designated at the highest status as National Historic Landmark (NHL) sites.

History

After its founding in 1916, the National Park Service initially oversaw sites of primarily scenic and natural significance, including national parks and national monuments. Historians soon began recommending preservation of sites relating to human history.^[5] Congress created Colonial National Monument in 1930 to protect the Jamestown Settlement and Yorktown battlefield in Virginia as one of the first new historical areas, and it was renamed a national historical park in 1936.^[5] Morristown National Historical Park, the 1779–1780 winter encampment of the Continental Army in New Jersey, was established on March 2, 1933, as its largest historical area. The U.S. House committee noted that the new designation was logical for the area and set a new precedent, with comparison to the national military parks, which were then in the War Department. The park's establishment allowed the NPS to have an administrative historical program with professional historians.^[6] President Franklin D. Roosevelt reorganized the agency to also oversee memorials and military parks with historic significance later in 1933, substantially broadening the NPS's mandate.^[7]

In 1935, Congress passed the Historic Sites Act (Pub. L.Tooltip Public Law (United States) 49–666), which established that "it is a national policy to preserve for public use historic sites, buildings and objects of national significance for the inspiration and benefit of the people of the United States."^[8] This expanded upon the Antiquities Act of 1906, which gave the President the ability to order "the protection of objects of historic and scientific interest." The Historic Sites Act directed the National Park Service to survey historic sites which may be of national significance, as well as restore and acquire properties. The Historic American Buildings Survey began to document the country's architectural heritage and identify buildings for potential protection. Initially the Secretary of the Interior could designate national historic sites, though this did not include funding for acquition or administration without congressional action.^[7] Salem Maritime National Historic Site was the first place to be preserved as a national historic site, created by secretarial order on March 17, 1938.^[9] It had followed Secretary Harold L. Ickes's designation of the Jefferson National Expansion Memorial in 1935; many historic sites in the National Park System continue to be protected under different designation types.^[7] Hopewell Furnace National Historic Site was designated later that year, another example of industrial heritage.

As the NPS developed criteria for nationally significant historic sites in the late 1930s, it aimed to identify unique sites that could each tell a broad story and would fit together to cover all aspects of American history. Surveys of sites were guided by themes and chronologies to ensure a diverse and comprehensive selection of those most representative of different eras and geographies, with less political influence over site selection.^[10] In the 1950s, the Mission 66 program revived historic studies that had lagged during World War II and saw the creation of the National Historic Landmarks program as a method to recognize important sites. From the 1960s to 1990s, the NPS evolved from a thematic framework, in which numerous specific themes and subthemes of American history were expected to each be included in some way in the system,^[11] to a conceptual framework, whereby both new and existing park units would be examined more holistically for ways to study history such as "creating social movements and institutions," "developing the American economy," and "peopling places." In the 20th century, potential new park units have been recommended not so much on "an orderly, balanced, and comprehensive" preservation of "outstanding examples", as Chief Historian Ronald Lee put it, but on those mandated to be studied by Congress, most of whose requests are recommended against by the NPS.^[10]

A 1973 NPS publication outlined policies for administration of historical areas, which were distinct from its natural and recreational areas. This included not only NHSes and NHPs but also national military parks, national battlefields, national battlefield parks, national battlefield sites, national memorial, and some national monuments; at that time there were 178 such areas, and management focused on "maintaining and where necessary restoring the historical integrity of structures, sites and objects significant to the commemoration or illustration of the historical story".^[12] But because most units contained a combination of natural, historic, and recreational lands, the General Authorities Act of 1970 made all areas equal within the National Park System;^[13] separate policy manuals for each were replaced in 1975 with one that would tailor policies in each park respective to the purpose of zones within.^[7]

National Historic Sites

National Historic Sites are generally federally owned and administered properties, though some remain under private or local government ownership. There are currently 85 NHSs, of which 75 are official NPS units, 9 are NPS affiliated areas, and one is managed by the United States Forest Service.

Derived from the Historic Sites Act of 1935, a number of NHSs were established by United States Secretaries of the Interior, but most have been authorized by acts of Congress. In 1937, the first NHS was created in Salem, Massachusetts, in order to preserve and interpret the maritime history of New England and the United States.

Fort Davis		Texas	523.00 acres (2.1165 km2)	Originally established in 1854 to protect emigrants, mail coaches, and freight wagons on the trans-Pecos portion of the San Antonio-El Paso Road and the Chihuahua Trail, the fort saw very sparse use. Thus, it remains one of the best examples of a United States Army fort in the southwestern United States. The fort also holds particular importance in regards to African-Americans in the army, as the 9th and 10th Cavalry regiments (all-black regiments also known as "The Buffalo Soldiers") were stationed at Fort Davis after the Civil War, helping rebuild the site.[40]
Fort Laramie		Wyoming	873.11 acres (3.5334 km2)	Founded as a private trading-post in the 1830s to service the overland fur trade, the site became an important trading post due to its location near the South Pass of the Rocky Mountains.

In 1937, the Golden Gate Bridge was built directly above the fort, though it is a part of the Golden Gate National Recreation Area and not the site itself.[43]
Fort Raleigh		North Carolina	515.73 acres (2.0871 km2)	This site preserves Roanoke Colony, the first English settlement in the present-day United States. Founded in 1587 by Sir Walter Raleigh, the colony was abandoned sometime between 1587 and 1590 and no survivors were discovered; many have dubbed it the "Lost Colony". During the American Civil War, the site became the Roanoke Island Freedmen's Colony, a contraband camp for slave refugees overseen by the Union Army.[44]
Fort Scott		Kansas	20.11 acres (0.0814 km2)	Established in 1842 as a midway point between Fort Leavenworth and Fort Gibson, Fort Scott provided protection to settlers migrating west from Native Americans in the Great Plains. The site saw little attention until the passage of the Kansas-Nebraska Act in 1854. Free-soilers and pro-slavery advocates occupied separate parts of the fort, leading to continued conflict. The Union Army took the fort during the American Civil War, holding it throughout the war.[45]
Fort Smith		Arkansas, Oklahoma	75.00 acres (0.3035 km2)	Established in 1871, Fort Smith contains the building which once housed the United States District Court for the Western District of Arkansas, which had jurisdiction over federal cases in Indian Territory.

The site highlights the influence of Swedish culture and people on early America.[52]
Grant–Kohrs Ranch		Montana	1,618.43 acres (6.5496 km2)	Originally established for fur trading in 1862, this ranch would eventually grow to cover over ten million acres of Powell County, Montana under the ownership of cattle baron Conrad Kohrs. Though the current-day park is only 1,618 acres, it illustrates the role of cattlemen in American history.[53]
Grey Towers		Pennsylvania	102 acres (0.41 km2)	Also known as the Gifford Pinchot House or the Pinchot Institute, this house was the home of Gifford Pinchot, the first head of the United States Forest Service. The house was commissioned in 1884 by Pinchot's father, James Pinchot, and remained in the Pinchot family until 1960, when the property was donated to the Forest Service.

A restored water wheel continues to pump air for the furnace. Community buildings include the Ironmaster's Mansion, office, barn, church, and workers' quarters.[60]
Hubbell Trading Post		Arizona	160.09 acres (0.6479 km2)	Following the Long Walk of the Navajo, many Navajo returned to the Ganado region of Arizona to restart their lives. Finding their homes and crops devastated, trade became an important means of economic growth for the Navajo. Established in 1878, J. Lorenzo Hubbell's trading post in Ganado, Arizona serves as the oldest operating trading post on the Navajo Nation.[61]
James A. Garfield		Ohio	7.82 acres (0.0316 km2)	20th President of the United States James A. Garfield was assassinated less than a year into his term, yet lived an accomplished life as an attorney, member of the Ohio State Senate, and United States Representative.

Little Rock Central High School		Arkansas	28.22 acres (0.1142 km2)	When opened in 1927, Little Rock Central was the nation's largest and most expensive high school facility. In 1957, the school gained international attention during the Little Rock Integration Crisis, when nine African-American students were denied entry to the school by students, protestors, and the state's governor. As this was in defiance to the recent ruling of Brown v. Board of Education, President Dwight D. Eisenhower deployed the 101st Airborne Division and the Arkansas National Guard to escort the students to school and deter protestors. The school itself is not open to the public as part of the site, but nearby visitor centers tell the school's history and provides streetscape walking tours with park rangers.[69][70]

International Historic Site

There is one International Historic Site in the US park system, a unique designation given to Saint Croix Island, Maine, on the New Brunswick border. The title, given to the site of the first permanent French settlement in America, recognizes the influence that it has had on both Canada and the United States. The NPS does not distinguish among these designations in terms of their preservation or management policies.

National Historical Parks

National historical parks tend to be larger and more complex than national historic sites. In the United States, sites are "historic", while parks are "historical". The NPS explains that a site can be intrinsically historic, while a park is a modern legal invention. As such, a park is not itself "historic", but can be called "historical" when it contains historic resources. It is the resources which are historic, not the park.^[109] There are 63 national historical parks.
