The old Clayton County Jail is quite old as surviving Georgia jails go, and has one of the more unusual forms I’ve seen. The parapetted facade is common enough, but the narrow overall depth is unusual.
As can be faintly seen in the photo below, an off-center, narrow wing containing jail cells protrudes at the rear of the structure. It is even narrower than the front of the building.
The structure has most recently served as the home of the Clayton County History Center.
