11 Most Endangered Historic Places

Since 1988, the National Trust has used its list of America's 11 Most Endangered Historic Places to raise awareness about the threats facing some of the nation's greatest treasures. The list, which has identified more than 300 sites to date, has been so successful in galvanizing preservation efforts that only a handful of sites have been lost.

The 2021 list includes a diverse mix of historic places nationwide that celebrate the interconnection of American culture and acknowledge it as a multicultural fabric that, when pieced together, helps tell the full American story.

Dozens of sites have been saved through the tireless work of the National Trust, its partners, and local preservationists across the country. Many more sites are now considered "favorable" and are on the path to a positive solution. Still, others remain threatened, and the National Trust and its partners continue in their efforts to save America's historic sites.

We are now accepting Letters of Intent for the 2022 list of America's 11 Most Endangered Historic Places. The deadline for submissions is Friday, November 12 at 11:59 p.m. Eastern Standard Time. Learn more about the application process and begin your submission here.
