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."
