NEW YORK (AP) -- The African Burial Ground National Monument in lower Manhattan was one of more than 300 sites around the country marking the 50th anniversary of Rev. Martin Luther King's "I Have A Dream" speech.
About a dozen visitors were at the monument in New York City on Wednesday to listen as a bell rang out around 3 p.m., accompanied by a West African drum. Other places around the nation from Alaska to the National Cathedral in Washington also rang bells to commemorate King's call to "let freedom ring."
The timing of the commemoration marked the time King gave his speech on Aug. 28, 1963, at the March on Washington.
The monument marks part of the grounds where thousands of African slaves and their descendants were once buried.
