Join Jesse Blackwood of Alithea Travel on a walk through Rome as he visits some of the outdoor architectural highlights of the city.

Join Molly at the ruins of the McIntosh Sugar Mill in St. Marys, Georgia, where she discusses a rare historic building material – tabby! The Spanish invented this early form of concrete: oyster shells, lime, sand, and water in the 16th and 17th centuries, and it remained a popular building material under the British and Americans in the Southeastern U.S. until the early 1800s.
