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 270 sites to date, has been so successful in galvanizing preservation efforts that only a handful of sites have been lost.

To mark the 30th anniversary of the America’s 11 Most Endangered Historic Places list, we are highlighting 11 once-endangered sites that are now thriving and contributing to their communities. The diverse range of places on this list reflect not only their rich history and compelling stories, but also the tireless dedication of the people who brought each place back from the brink.

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 protect these important endangered places.
