When did The National Museum of African-American History and Culture in Washington, D.C. open?
Washington D.C. is the place to be to learn about history, and now there's one more place for visitors to check out. It took 13 years of planning and preparation for the NMAAHC to become the latest addition to D.C.'s museums, opening on Sept. 24, 2016. The 400,000-square-foot building contains 36,000 artifacts spanning the entire history of African-American culture. Source: Smithsonian Magazine
