(February), and on the anniversary of King's April 4, 1968, assassination in Memphis, Tennessee. Preservation The Martin Luther King Jr. Historic District, an area bounded roughly by Irwin, Randolph, Edgewood, Jackson, and Auburn avenues, was listed on the U.S. National Register of Historic Places on May 2, 1974. The district included Ebenezer Baptist Church, King's grave site and memorial, Dr. King's birthplace, shotgun row houses, Victorian houses, the Atlanta Baptist Preparatory Institute site, Our Lady of Lourdes Catholic Church, Fire Station No. 6, and the Triangle Building at the intersection of Old Wheat Street and Auburn Avenue. Much of the area was designated as a national historic landmark district on May 5, 1977. The Trust for Public Land purchased 5 single-family homes along Auburn Avenue in the late 1970s, the same block Martin Luther King Jr. grew up on. The Trust for Public Land purchased more than a dozen properties over the next 20 years to create a parking lot as well as a pedestrian greenway to link the King district to the Jimmy Carter Presidential Center. In 2008, The Trust for Public Land acquired one of the remaining historic properties in the neighborhood, on the corner of Auburn Avenue. By U.S. Congressional legislation, the site with associated buildings and gardens was authorized as a national historic site on October 10, 1980; it is administered by the National Park Service (NPS).

In 2018, it was redesignated as a national historical park, adding Prince Hall Masonic Temple to the protected area.
