Savannah’s NAACP chapter celebrated its centennial this fall at the historic First African Baptist Church. The church was also honored by the Georgia Historical Society earlier this year for its extensive role in African-American history and the civil rights movement, from hiding people on the underground railroad, to being the site of Dr. Martin Luther King Jr.’s first public speech in 1944. GPB’s Ryan McFadin went to a Sunday service, and sent back an audio postcard.
