Mason Temple, located in Memphis, Tennessee, is a Christian international sanctuary and central headquarters of the Church of God in Christ, the largest African American Pentecostal group in the world. The building was named for Bishop Charles Harrison Mason, founder of the Church of God in Christ, who is entombed in a marble crypt inside the Temple.
Mason Temple was the site of Martin Luther King Jr.'s 1968 "I've Been to the Mountaintop" speech the night before his assassination.
