Mason Temple, a flagship sanctuary for the Church of God in Christ (COGIC), was once the largest African-American church in the country. The temple, listed on the National Register of Historic Places, has also played a pivotal role in the civil rights movement.
It was at Mason Temple that Martin Luther King Jr. delivered his famous “I’ve Been to the Mountaintop” speech in 1968. Mason Temple served as a spiritual center for the black community throughout the 1950s and 1960s.
