Just south of Savannah Georgia on Coastal Hwy US 17 in Townsend Georgia you can visit the smallest church in America. Recently rebuilt due to a fire it is a quiet spot with a picnic area if you are traveling in the area.  Along this route there are many historic markers and further south is the City of Darien.  Definitely worth the stop if you are in the coastal Georgia area and it gets you off I95 for some site seeing.
