The "red-rose" city of Petra stands as one of the most glorious and mysterious archaeological sites on earth. Created over 2,500 years ago, the ornate Petra cityscape was literally carved into the rose-colored walls of Jordan's Shara Mountains.

What was Petra and could the Arabian site be still hiding precious treasure? Join host Josh Bernstein as he examines Petra's only surviving parchment manuscript, and goes underneath the ancient "Treasury" in search of hidden riches.
