For Black History Month, the Association for the Study of African American Life and History is building on the National Park Service’s “Journey through Hallowed Ground” to honor the contributions African Americans have made to our country. The Black History Month 2016 theme, Hallowed Grounds: Sites of African American Memories includes a complete list of historic landmarks that have been certified by the National Park Service’s National Register of Historic Places.
