A National Historic Landmark (NHL) is a building, site, structure, or object that is officially recognized by the United States government for its national-level historical significance. Out of more than 85,000 places on the National Register of Historic Places only about 2,430 are NHLs.

A National Historic Landmark District (NHLD) is a historic district that has received similar recognition. The district may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed.

Famous quotes containing the words national, historic and/or landmark:

    While I do not think it was so intended I have always been of the opinion that this turned out to be much the best for me. I had no national experience.

The Presidents who have gone to Washington without first having held some national office have been at great disadvantage.
    Calvin Coolidge (1872–1933)

    It is, all in all, a historic error to believe that the master makes the school; the students make it!
    Robert Musil (1880–1942)

    His landmark is a kopje-crest
    That breaks the veldt around;
    Thomas Hardy (1840–1928)
