Yellowstone. The Everglades. Great Smoky Mountains. It might be surprising to find the Frederick Douglass National Historic Site at 1411 W St. SE in the company of these vaster expanses of the National Park Service. Yet the D.C. landmark has the dubious distinction of joining these and six other sites on the National Parks Conservation Association’s (NPCA) annual list of America’s Ten Most Endangered Parks. The influential abolitionist resided in the home for the final 18 years of his life, and the NPCA points to a $2 million gap in funding to make interior and exterior repairs, and protect books, photographs, and other memorabilia from deterioration as the reason for including the site on its list. —Richard Byrne
