African Burial Ground National Monument

African Burial Ground National Monument at Duane Street and African Burial Ground Way (Elk Street) in Lower Manhattan (New York City) preserves a site containing the remains of more than 400 Africans buried during the late 17th and 18th centuries in a portion of what was the largest colonial-era cemetery for people of African descent, some free, most enslaved. Historians estimate there may have been 15,000-20,000 burials in what was called the "Negroes Burial Ground" in the 1700s. The site's excavation and study was called "the most important historic urban archeological project in the United States."

The discovery highlighted the forgotten history of African slaves in colonial and federal New York City, who were integral to its development. By the American Revolutionary War, they constituted nearly a quarter of the population in the city, which had the second largest number of slaves in the nation after Charleston, South Carolina. Scholars and African-American civic activists joined to publicize the importance of the site and lobby for its preservation. In 1993 the site was designated a National Historic Landmark and in 2006 a National Monument.

In 2003 Congress appropriated funds for a memorial at the site and directed redesign of the federal building to allow for this. A design competition attracted more than 60 proposals for a design. The memorial was dedicated in 2007 to commemorate the role of Africans and African Americans in colonial and federal New York City, and in United States history. A visitor center opened in 2010 to provide interpretation of the site and African-American history in New York.
