Historic preservation in New York is activity undertaken to conserve forests, buildings, ships, sacred burial grounds, water purity and other objects of cultural importance in New York in ways that allow them to communicate meaningfully about past practices, events, and people.

Governmental programs for historic preservation range from Federal ownership and active operation of sites (such as the Statue of Liberty and Ellis Island in New York Harbor) to grants and subsidies provided by state government, municipal support of museums and interpretative displays (such as roadside plaques and town-history websites). Nonprofit programs include activities of statewide and local historical associations and museums, and activities of historical societies and museums at the national level. Quasi-governmental organizations, such as the New York State Thruway Authority and Thousand Islands Bridge Authority (which have historic sites on their property), play a role as well. Private endeavors, such as investment and other choices made by private landowners to conserve historical features of their properties, are significant but less visible and include groups such as the Historic Districts Council, The New York Landmarks Conservancy and the Preservation League of New York State.

Federal programs Federal programs include National Park Service areas, the National Register of Historic Places (including its tax subsidies) and the National Historic Landmark program.

National Park Service areas New York has no National Parks, but there are 20 other National Park Service areas that primarily protect historical sites. These provide the highest degree of conservation provided by the Federal government.

There are five National Monuments: African Burial Ground National Monument, declared February 27, 2006, (also a National Historic Landmark) Castle Clinton National Monument, declared August 12, 1946 (also an NHL) Fort Stanwix National Monument, declared August 21, 1935 (also an NHL) Governors Island National Monument, declared January 19, 2001 (also an NHL) Statue of Liberty National Monument, declared October 15, 1924 (shared with New Jersey)

There are two National Historical Parks: Saratoga National Historical Park Women's Rights National Historical Park

There are eight National Historic Sites: Eleanor Roosevelt National Historic Site Home of Franklin D. Roosevelt National Historic Site Martin Van Buren National Historic Site Sagamore Hill National Historic Site Saint Paul's Church National Historic Site Theodore Roosevelt Birthplace National Historic Site Theodore Roosevelt Inaugural National Historic Site Vanderbilt Mansion National Historic Site

There are three National Memorials: Federal Hall National Memorial General Grant National Memorial Hamilton Grange National Memorial (also an NHL)

There are also two National Historic Site "associated areas", which receive National Park Service support but are not administered by the NPS: Lower East Side Tenement National Historic Site (also an NHL) Thomas Cole National Historic Site (also an NHL)

National Historic Landmarks

The National Historic Landmark program has designated 257 landmarks in New York, which is more than 10% of all NHLs in the United States. Seven of these are also National Park Service areas.

Registered Historic Places

There are over 5,000 properties and districts listed on the National Register of Historic Places in New York. These include all of the historic NPS areas listed above, and all of the NHLs.

State programs New York State programs include State Historic Sites and state-listed historic sites.

State Historic Sites

There are 38 State Historic Sites; 23 of these are also NHLs. All the NHLs (and some of the others) are also NRHP-listed. The state historic sites are:

Bennington Battlefield State Historic Site (Bennington Battlefield NHL) Caumsett State Historic Park Clermont State Historic Site (Clermont Manor NHL) Clinton House State Historic Site Crailo State Historic Site (Fort Crailo NHL) Crown Point State Historic Site (Fort Crown Point NHL and Fort Frederic NHL) Darwin Martin House State Historic Site (Darwin D. Martin House NHL) Fort Montgomery State Historic Site (Fort Montgomery NHL) Fort Ontario State Historic Site Ganondagan State Historic Site (Boughton Hill NHL) Grant Cottage State Historic Site Herkimer Home State Historic Site Hyde Hall State Historic (Hyde Hall NHL) Jay Heritage Center John Brown Farm State Historic Site (John Brown Farm and Gravesite NHL) John Burroughs Memorial State Historic Site (Woodchuck Lodge NHL) John Jay State Historic Site (John Jay House NHL) Johnson Hall State Historic Site (Johnson Hall NHL) Knox's Headquarters State Historic Site (Knox Headquarters NHL)

State-listed historic sites The state Department of Historic Preservation – within the New York State Office of Parks and Recreation—Historical Preservation (NYSOPRHP) – is heavily involved in evaluating candidates for NRHP listings. Sites are given a state listing first, and some are then nominated for a Federal listing; thus, sites may receive a state but not a Federal listing. Owners of sites may opt out of a Federal listing, but may not be able to opt out of state listing.

New York City programs The New York City Landmarks Preservation Commission was founded (after the demolition of the original Penn Station building) to identify and preserve landmarks in New York City.

Quasi-governmental organizations The Thousand Islands Bridge Authority acquired Boldt Castle on Heart Island and its nearby yacht house for one dollar in 1977, under an agreement that all revenue obtained would be used to preserve the castle. The George C. Boldt Yacht House is on the National Register of Historic Places. The New York State Thruway Authority subsidizes the preservation of the New York State Barge Canal."Revenue-draining canal should be cut from Thruway". Utica (New York) Observer-Dispatch, January 9, 2008. Retrieved 2011-04-12.

Archeological investigations The African Burial Ground (the latest National Monument in New York) was discovered during construction activities in downtown New York City. Road-construction projects are required to have subcontractors who investigate sites for archeological importance (Indian remains, for example). Archeological sites are sometimes preserved in secrecy, although some are pilfered by amateur archeologists. It is National Park Service policy to conceal the location of sensitive archeological sites by withholding location information on NRHP documents (or withholding NRHP documents altogether from the public).
