Today, the nonprofit National Trust for Historic Preservation published its annual list of the most endangered historic places in the United States.

Every year, the nonprofit aims to galvanize Americans to help local communities preserve historically significant buildings and sites under threat of destruction from factors such as natural disasters, pressure for infrastructure development, and disrepair. Since the designation’s establishment in 1988, almost 300 threatened places have been identified. Less than five percent of those sites have been destroyed thanks to the awareness and community fostered by the organization.

This year’s designated sites include a neglected early Modernist house in Texas, a Maryland park that, due to construction of a gas compressor, faces the loss of its historic viewshed of Mount Vernon, and five secondary schools—each central to the 1968 East LA student walkouts—which are being threatened with demolition. The full list includes 11 historic places and one-of-a-kind treasures throughout the nation: 

●       Annapolis’ City Dock Area – Annapolis, MD

●       Ashley River Historic District – Charleston County, S.C.

●       Dr. Susan LaFlesche Picotte Memorial Hospital – Walthill, NE

●       Historic Resources of Puerto Rico and the U.S. Virgin Islands

●       Isaiah T. Montgomery House – Mound Bayou, MS

●       Larimer Square– Denver, CO

●       Mary and Eliza Freeman Houses – Bridgeport, CT

●       Mount Vernon & Piscataway National Park, Mount Vernon, VA. and Accokeek, MD

●       Route 66 – Multiple States

●       Ship on the Desert – Salt Flat, TX

●       Walkout Schools of Los Angeles – Los Angeles, CA

The nonprofit also included a 12th site, reserved for historical locations with growing, less eminent threats. Four Towns of Vermont’s Upper Valley—charming village centers surrounded by farms and forests in rural Vermont—are at risk of being permanently altered by a development proposal to construct a new planned community.

“From the East L.A. Chicano Student Walkout schools to Route 66, America’s Mother Road, to historic resources in Puerto Rico and the U.S. Virgin Islands severely damaged by last year’s hurricanes, this year’s list reflects both the diversity of America’s historic places and the variety of threats they face,” says Stephanie K. Meeks, president and CEO of the National Trust for Historic Preservation. "We hope this list inspires people to speak out for the cherished places in their own communities that define our nation’s past.”
