The National Trust for Historic Preservation (NTHP) recently released its 2011 list of America’s 11 Most Endangered Historic Places. To see the list of endangered sites visit the Trust’s website.

NTHP has annually released the list to raise awareness of the serious threats facing the nation’s greatest treasures. Since the program’s inception, the Trust has identified 233 endangered sites. The program has been so successful in galvanizing preservation efforts across the country that, in over two decades, only a handful of sites have been lost.
