Today, the Martin Luther King, Jr. National Historical Park is a 38.4-acre park consisting of a Visitor Center, Historic Ebenezer Baptist Church (Heritage Sanctuary), The King Center, Historic Fires Station No. 6, King Birth Home, Historic Residential Area, Prince Hall Masonic Building, where the Southern Christian Leadership Conference (SCLC) relocated their headquarters in 1963 and the Family Home of Dr. Martin Luther King, Jr., and Mrs. Coretta Scott King. Rev. Dr. Martin Luther King, Jr. was the first co-pastor of the Historic Ebenezer Baptist Church, serving with his father from 1960 to April 4, 1968. His brother, Rev. Alfred Daniel Williams King served as co-pastor, until his tragic death on July 21, 1969. Their father, Daddy King, retired from active ministry in 1975, nearly a year after his wife, Mrs. Alberta Christine Williams King (Mama King) was assassinated in Ebenezer on June 30, 1974.
