It covers and includes the Stone of Hope, a granite statue of Civil Rights Movement leader Martin Luther King Jr. carved by sculptor Lei Yixin.

The memorial opened to the public on August 22, 2011, after more than two decades of planning, fund-raising, and construction. This national memorial is the 395th unit in the United States National Park Service.
