The United States National Historic Landmark Program is designed to recognize and honor the nation's cultural and historical heritage. The program was formally inaugurated with a series of listings on October 9, 1960; as of August 21, 2020, there are 2,597 designated landmarks. A National Historic Landmark (NHL) is generally a building, district, object, site, or structure, that is officially recognized by the United States government for its national historical significance. A National Historic Landmark District (NHLD) is a historic district that is recognized as an NHL. Its geographic area may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties.


The program is administered by the National Park Service (NPS), a branch of the Department of the Interior. The National Park Service determines which properties meet NHL criteria and makes nomination recommendations after an owner notification process. [1] The secretary of the interior reviews nominations and, based on a set of predetermined criteria, makes a decision on NHL designation or a determination of eligibility for designation. [2] Both public and privately owned properties can be designated as NHLs. This designation provides indirect, partial protection of the historic integrity of the properties via tax incentives, grants, monitoring of threats, and other means. [1] Owners may object to the nomination of the property as an NHL. When this is the case the secretary of the interior can only designate a site as eligible for designation. [2]

All NHLs are also included on the National Register of Historic Places (NRHP), a list of some 80,000 historic properties that the National Park Service deems to be worthy of recognition. The primary difference between an NHL and a NRHP listing is that the NHLs are determined to have national significance, while other NRHP properties are deemed significant at the local or state level. [1]

Tabular listing

Most landmark designations are in one of the 50 states. New York is the state with the most (270), and New York City, with 114 designations, is the city with the largest number of designations. Of the states, North Dakota has the fewest designations with seven. Three cities (New York City, Philadelphia, and Boston) have enough listings to warrant lists separate from their respective states.

A small number of designations have been made outside the 50 states. Most of these appear in United States possessions. The Virgin Islands have five listings, Puerto Rico has four, and island possessions in the South Pacific have six. Five listings are found in Pacific island nations with which the U.S. has established a free association agreement, and one listing, the American Legation in Tangier (the nation's first foreign public property), is found in the unaffiliated Kingdom of Morocco.

The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures, and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property.

A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500, or roughly three percent, of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks.

<span class="mw-page-title-main">National Natural Landmark</span> Natural areas program in the U.S.

The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall.

The history of the National Register of Historic Places began in 1966 when the United States government passed the National Historic Preservation Act (NHPA), which created the National Register of Historic Places (NRHP). Upon its inception, the U.S. National Park Service (NPS) became the lead agency for the Register. The Register has continued to grow through two reorganizations, one in the 1970s and one in 1980s and in 1978 the NRHP was completely transferred away from the National Park Service, it was again transmitted to the NPS in 1981.

The U.S. National Register of Historic Places (NRHP) classifies its listings by various types of properties. Listed properties generally fall into one of five categories, though there are special considerations for other types of properties which do not fit into these five broad categories or fit into more specialized subcategories. The five general categories for NRHP properties are: building, district, object, site, and structure.
