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

On May 9 we are announcing the 2023 list of America’s 11 Most Endangered Historic Places and this year’s lineup features incredible work from a wide array of communities who are working hard to protect threatened places they care about. Sign up for emails and be among the first to get the news.

The two exhibits on Google Arts & Culture provide a look back on six different places that previously were on the 11 Most Endangered Historic Places list. Read about each site's significance, hear directly from advocates about the impact of the listing on the preservation of the site, and learn how you can help.
