Martin Luther King Jr. Memorial

The Martin Luther King Jr. Memorial is in West Potomac Park next to the National Mall in Washington, D.C., United States. 
It covers and includes the Stone of Hope, a granite statue of Civil Rights Movement leader Martin Luther King. The inspiration for the memorial design is a line from King's "I Have A Dream" speech: "Out of the mountain of despair, a stone of hope." 
The memorial opened to the public on August 22, 2011, after more than twenty years of planning, fund-raising, and construction.
