The Post and Courier of Charleston reports that Charleston City Council has approved an agreement with the National Park Service to place the memorial at Liberty Square - the four-acre park at the Fort Sumter National Monument Visitors Center in Charleston.
Fort Sumter Superintendent Tim Stone says the monument is appropriate for the square.
A citizens committee working on the memorial will decide its design and then raise money. There is no estimate of the cost.
The only public tribute to King in Charleston is a street sign marking a neighborhood as the Martin Luther King Jr. Memorial District.
