The legend of El Dorado has fascinated explorers since the days of the Spanish Conquistadors and sparked what may be the bloodiest gold rush in history. The mythical lost city of gold was inspired by an opulent ancient Colombian tribe, and while the culture has disappeared, an invaluable relic of theirs--a small golden raft statue--lives on. Host Adam Mastrelli tracks a team of metal experts and archaeologists as they study this artifact in hopes of unlocking the secrets of this fabled city and discovering the truth of a vanished civilization.

The Tower of Babel is one of the most dramatic stories in the Bible, an apocalyptic tale of the construction of a mighty stairway to heaven that was destroyed by the wrath of God. Now, an incredible discovery suggests that this immense structure wasn't simply a work of fiction, but existed in the legendary city of Babylon. Host Adam Mastrelli examines the mysteries of this lost wonder of the ancient world, the legendary King Nebuchadnezzar II who built it, and his prisoners of war, who may have inspired the biblical tale.
