 Fairfield County has numerous churches, some of which have existed for over 200 years.Perhaps the most famous church, built in 1788, is the Old Brick Church, where the Associate Reformed Presbyterian Synod of the Carolinas was organized in 1803.A note penciled on the wall of the Old Brick Church is testimony to a Union soldier's regret at the church's floor boards being taken up to build a crossing over the nearby river for General Sherman's troops during the American Civil War.
