Atlanta is now the home of a new major attraction that embodies the living history of the civil rights movement. The National Center for Civil and Human Rights opened Monday in downtown Atlanta, after almost a decade of planning.

The gleaming 42,000 square-foot museum has permanent exhibits about the civil rights movement, including the personal papers of Martin Luther King, Jr. It will also have rotating exhibits about ongoing struggles worldwide.

One of those exhibits focuses on the 1963 bombing of the 16th Street Baptist Church in Birmingham, where four young girls were killed.

Barbara Cross’ father was the pastor of the church. She says the pain hasn’t gone away, even though the bombing happened more than 50 years ago.
