A 2014 museum next to Centennial Olympic Park that places the American civil rights movement of the 1950s and 60s in the context of the global human rights struggle. The upstairs galleries cover Martin Luther King Jr.'s papers — the museum holds his archives, on loan from Morehouse College — alongside Mahatma Gandhi, Nelson Mandela, and contemporary movements.
The downstairs civil rights gallery and the lunch-counter exhibit are emotionally exhausting in the way the best of these museums should be. Allow at least two hours. The architecture, by Philip Freelon, is itself worth a look.
