St. Mark’s Episcopal Church is in the small southern Georgia town of Woodbine. It was built in 1900 and has tabby covering the exterior walls. Tabby was once common on old structures in the region, first used by Spanish settlers, and then later by English colonists. It’s made by burning oyster shells to create lime, and then mixing it with water, sand, ash, and broken oyster shells to form a concrete type of mixture. Below is an example from a tabby slave quarters from Kingsley Plantation in northern Florida.
On the way back through town I also passed the church below named Ebenezer Missionary Baptist Church. Nothing yet on the history here.
