Overlooking Franklin Square is First African Baptist Church. This church, which is still active, is descended from the oldest African-American congregation in the United States. George Leile, a slave, began making missionary visits to plantations up and down the Savannah River as early as 1774. A permanent congregation was formed at Brampton Plantation in 1788—the first black missionary Baptist church in Savannah. Eventually, the congregation constructed the current building. It is the first brick building erected in Georgia by African-Americans for African-Americans; it was built by slaves who worked on it at night after being in the fields all day. The sanctuary has beautiful stained-glass windows framing the back of the altar, which displays pictures of the founding pastors. In the balcony are original pews with markings left by the slaves who built the church.
