The museum's building, collaboratively designed by Freelon Group, Adjaye Associates and Davis Brody Bond, is on the National Mall in Washington, D.C. It has close to 37,000 objects in its collection related to such subjects as community, family, the visual and performing arts, religion, civil rights, slavery, and segregation . </P> <P> Early efforts to establish a federally owned museum featuring African - American history and culture can be traced to 1915, although the modern push for such an organization did not begin until the 1970s . After years of little success, a much more serious legislative push began in 1988 that led to authorization of the museum in 2003 . A site was selected in 2006 . The museum opened September 24, 2016, in a ceremony led by U.S. President Barack Obama . </P>
