text: List of National Historic Landmarks in New York
Historic areas in the United States National Park System
National Historic Sites , National Historic Parks , National Memorials , and certain other areas listed in the National Park system are historic landmarks of national importance that are highly protected already , often before the inauguration of the NHL program in 1960 . There are 20 of these in New York State . The legislation establishing the National Historic Landmark program does not prevent these from being designated , [ 12 ] but in practice these are not often named NHLs per se , due to administrative costs of their nomination and to the low preservation value of designating them . [ 13 ] For the first 16 years of the National Historic Landmarks program , the National Park Service did not consider any sites already within the National Park system for NHL designation , and in fact if a NHL-designated site came into the NPS system it was de-designated . [ 13 ] :94–95 In New York State , the William Floyd House within the Fire Island National Seashore and Ellis Island within the Statue of Liberty National Monument were both deemed NHL-eligible by the Advisory Board but were not designated . [ 13 ] :95 It was not until 1977 that a policy was promulgated that would allow for designation of National Historic Landmark `` whose primary significance is not related to its park 's purpose '' . [ 13 ] :96 The Jacob Riis House in Queens was de-designated in 1973 . [ 13 ] :105 The National Park Service identifies 18 historic sites within national park units in New York State , and lists these together with the NHLs in the state , [ 3 ] and there are also two National Historic Sites that are `` affiliated areas , '' receiving National Park Service support but not directly administered by it . [ nb 58 ] Seven of the 20 were declared National Historic Landmarks , in several instances before receiving the higher protection designation , and retain their NHL standing . Four of these are listed above and three are included within the New York City list of NHLs . The 13 others are :
This is a list of National Historic Landmarks and comparable other historic sites designated by the U.S. government in the U.S. state of New York. The United States National Historic Landmark (NHL) program operates under the auspices of the National Park Service, and recognizes buildings, structures, objects, sites and districts of resources according to a list of criteria of national significance. There are 262 NHLs in New York state, which is more than 10 percent of all the NHLs nationwide, and the most of any state. The National Park Service also has listed 20 National Monuments, National Historic Sites, National Memorials, and other sites as being historic landmarks of national importance, of which 7 are also designated NHLs. All of these historic landmarks are covered in this list. There are 139 NHLs in upstate New York, 13 on Long Island, and 114 within New York City (NYC). Three counties have ten or more NHLs: New York County (Manhattan) has 86; Westchester County, just north of NYC, has 18; and Erie County in western New York has 10. Twelve other counties have five to nine NHLs, eight have three or four, 27 counties have one or two, and the remaining twelve of the state's 62 counties have none. The first New York NHLs were eight designated on October 9, 1960; the latest was designated on March 13, 2013. The NHLs and other landmarks outside NYC are listed below; the NHLs in NYC are in this companion article. Seven NHL sites are among the 20 National Park System historic areas in New York state. The other 13 National Park Service areas are also historic landmark sites of national importance, but are already protected by Federal ownership and administration, so NHL designation is unnecessary.
