In 1991 workers excavating the foundation for a new building uncovered human remains, which turned out to be from the site where historians say 15,000 slaves were buried from 1640 to 1795 on nearly seven acres near what is now City Hall Park.
The African Burial Ground Monument is located just north of City Hall in a Federal Building
