In 2003, after time at the lab at Howard University, the remains from the African Burial Ground were returned to New York City in a grand ceremony. Each of the 419 sets of remains was placed in its own hand-carved coffin made in Ghana. The coffins were split between seven crypts. Each crypt—along with nearly eight thousand handwritten letters “from the living to the African ancestors”—was lowered into the ground and marked with seven burial mounds. The site was designated a National Historic Landmark in 1993, and in 2006 it was designated a National Monument by President George W. Bush.
