National Trust’s 20th List of America’s Most Endangered Historic Places: America’s priceless heritage is at risk—from the storied waterfront of Brooklyn to the neon-clad mom-and-pop motels of Route 66—some of America’s most irreplaceable landmarks are threatened. “The sites on this year’s list of America’s 11 Most Endangered Historic Places embody the diversity and complexity of America’s story, and the variety of threats that endanger it,” said Richard Moe, president of the National Trust for Historic Preservation. “The places on this year’s list span the continent and encompass the breadth of the American experience. Each one is enormously important to our understanding of who we are as a nation and a people.”
