These American landmarks are in danger of disappearing

Some of America’s landmarks are already gone, including Art Deco theaters, buildings designed by Frank Lloyd Wright and New York City’s original Pennsylvania Station. And there’s still a surprising number of existing spots that are neglected, unprotected and at risk – many of which are included on an annual list compiled by the nonprofit National Trust for Historic Preservation. Some are surprising, others you might never have heard of – but all are places that could be lost forever.
