The Smithsonian Institute began construction of the National Museum of African American History and Culture on Feb. 22, 2012. The museum, which, according to the NMAAHC website, "will be a place where all Americans can learn about the richness and diversity of the African American experience, what it means to their lives and how it helped us shape this nation," is set to open in 2015.
