Join a local guide in Paris to explore the paths of “The Da Vinci Code,” Dan Brown's novel and its film adaptation directed by Ron Howard. Begin in front of the Ritz Hotel, the setting for the film's final chapter. Discuss the ending and how Robert Langdon discovered the last piece of the puzzle.

Next, head to the Palais Royal, a historic palace and tranquil square featured in the film. Walk through the same passages as Robert Langdon (played by Tom Hanks) as he searches for the end of the rose line. See which elements of the storey exist in reality and which remain in the realm of fiction.
