Alexandria Black History Museum
This collection, devoted to the history of African Americans in Alexandria and Virginia, is housed in part in the Robert H. Robinson Library, a building constructed in the wake of a landmark 1939 sit-in protesting the segregation of Alexandria libraries. The Watson Reading Room, next to the museum, holds a vast collection of books, periodicals, videos, and historical documents detailing the social, economic, and cultural contributions of African Americans who helped shape the city's growth since its establishment in 1749. The federal census of 1790 recorded 52 free African Americans living in the city, but the town was one of the largest slave-exporting points in the South, with at least two highly active slave markets.
