The most recent session of the UNESCO World Heritage Committee is taking place right now in Saudi Arabia, and it was just announced that they are inscribing the 25th World Heritage Site in the United States — a group of eight ancient earthwork sites in southern Ohio — the Hopewell Ceremonial Earthworks.

In this episode, we'll delve into what's known of the history of the Earthworks and how a World Heritage Site gets listed.
