Completed in 2011, the memorial of Martin Luther King Junior along the National Mall celebrates his cultural leadership in confronting racism and inequality through non-violence.

The 30-foot tall granite sculpture is engraved with a line from King’s “I Have A Dream” speech that forms the basis of is symbolism: “out of a mountain of despair, a stone of hope.” He gave that speech at the Lincoln Memorial, steps away, on August 28, 1963.

An adjacent 450-foot long inscription wall features 14 quotes from Martin Luther King Junior.
