Sites associated with the childhoods of Martin Luther King Jr. and Malcolm X and the Ellis Island hospital complex where thousands of immigrants received medical treatment upon arriving in America are on the National Trust for Historic Preservation’s 2012 list of 11 endangered places, according to USA Today and the Associated Press.

The nonprofit trust, which annually publicizes sites, entities, or institutions it says are threatened by development or neglect, also included U.S. post offices on the 2012 roster, saying hundreds of historic mail facilities face uncertain futures as the Postal Service downsizes.

While Ellis Island is a popular tourist destination, its medical complex is dilapidated, the trust said. The group also cited Malcolm X’s boyhood home in Boston, which has been vacant and deteriorating for decades, and raised alarms about commercial redevelopment in Atlanta’s Sweet Auburn Historic District, where Martin Luther King Jr. was born.

Details about all the sites on the 2012 list are available at the trust’s Web site.
