New York is home to many monuments and memorials hidden in the shadows of the skyscrapers and crowds. For every period in American history, you can probably find a statue to commemorate it somewhere on the island.
The African Burial Ground National Monument at 290 Broadway was buried for years under urban development before being rediscovered in 1991. The 6.6 acre burial ground in lower Manhattan is a memorial to the 15,000 free and enslaved Africans who ended their journeys in the former New Amsterdam in the 17th and 18th centuries.
Those paying their respects and interested in American history can stop in to the free visitor center, which features four exhibit areas and a theatre.
