National Register of Historic Places: Current Listings by State and Territory
The National Register of Historic Places (NRHP) serves as the official list of the United States' districts, sites, buildings, structures, and objects deemed worthy of preservation for their historical significance. This comprehensive database captures the diverse architectural and cultural evolution of the nation, from colonial settlements to mid-century modern landmarks.
Because the NRHP is a living document, new entries are added on a weekly basis. The current tallies reflect data from the National Register Information Database as of August 16, 2025, supplemented by recent weekly updates. It is important to note that these figures are approximate and not official, as the list undergoes frequent additions and occasional delistings.
Key Facts
- Total Listings: There are approximately 98,388 total sites listed.
- Highest Volume: New York holds the highest number of listings with 6,476 sites.
- Global Reach: While primarily focused on the U.S., the register includes sites in Morocco, Palau, the Marshall Islands, and the Federated States of Micronesia.
- Exclusions: These counts exclude boundary increase and decrease listings, which modify the area of an existing property but carry separate reference numbers.
Distribution of Historic Sites Across the United States
The distribution of historic sites varies significantly by state, often reflecting the age of settlement, the intensity of urban development, and local preservation efforts. For instance, Northeastern states like Massachusetts (4,441) and New York (6,476) show high concentrations of registered sites.
In the Midwest and South, states such as Kentucky (3,478), Pennsylvania (3,561), and Texas (3,532) also maintain extensive lists of protected landmarks. These sites range from individual antebellum mansions to entire historic districts.
Territories and International Listings
The NRHP's scope extends beyond the 50 states. U.S. territories such as Guam (134), Puerto Rico (381), and the Virgin Islands (96) contribute significantly to the cultural record. Additionally, a small number of sites outside the United States are recognized, including a single site in Morocco.
