Each year, America’s 11 Most Endangered Historic Places sheds light on important examples of our nation’s heritage that are at risk of destruction or irreparable damage. More than 300 places have been listed in its 33-year history, and in that time, fewer than 5 percent of listed sites have been lost.

The 2020 list includes a diverse mix of historic places nationwide that highlight many of the cultures, stories, and experiences—including seven sites with significant connections to women’s history—that help tell the full American story.

But with threats ranging from neglect to natural disasters to inappropriate development, these special places are at serious risk. Browse the list below and learn what you can do to support these irreplaceable sites.
