=== Historic heritage ===
Owing to its millennia of habitation and over two centuries of Spanish colonial rule, New Mexico features a significant number of sites with historical and cultural significance. Forty-six locations across the state are listed by the [[U.S. National Historic Landmark|U.S. National Register of Historic Places]], the 18th highest of any state.<ref>{{Cite web|title=National Register Database and Research – National Register of Historic Places (U.S. National Park Service)|url=https://www.nps.gov/subjects/nationalregister/database-research.htm|access-date=2021-08-02|website=www.nps.gov|language=en|archive-date=August 28, 2018|archive-url=https://web.archive.org/web/20180828223402/https://www.nps.gov/subjects/nationalregister/database-research.htm|url-status=live}}</ref>
