The Revealer Returns

After a brief summer hiatus, our featured segment, "The Revealer", returns this Thursday!  So, you know what that means... the return of The Revealer Game.  Long-time fans of the show already know the drill:  In the days leading up to the debut of this week's Revealer segment, we will post new photographs each day, offering visual clues to the subject of this week's episode.

Here's the first clue:  It's a historic site that draws millions of tourists every year.  We know a great deal about how it was created.  But, for the longest time, no one was sure WHY it was built where it was.
