Read more about these significant sites and learn how you can support them.
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. Now in its 39th year, the annual list has identified more than 350 sites to date, and it has proven so successful in galvanizing preservation efforts that only a handful of sites have been lost.
The 11 Most Endangered program uplifts and catalyzes community-led preservation work through a high-impact public awareness campaign resulting in increased visibility, public attention, and new resources to save and activate historic places for the public good.
The places featured on the 2026 list of America’s 11 Most Endangered Historic Places span the country, from rural areas to densely populated city centers. Each of these places has different challenges and needs, but they are all united in how they illuminate stories of remarkable individuals who fought to bring our country closer to its founding aspirations of equality. These historic places, and the inspiring stories they preserve, are necessary so that America may learn from its past in the hopes of building a more perfect union.
Just as the tireless work of the National Trust, its partners, and local preservationists across the country have saved dozens of previously listed sites and set many more on a path to a positive solution, so now can we work together on behalf of these endangered places.
