Grail Location Revealed

Back in Paris, Langdon awakens from a long sleep with a sudden realization. He follows the ancient Parisian Rose Line, marked by bronze medallions, to the Louvre. He stands before the inverted glass pyramid, La Pyramide Inversée, and the small stone pyramid beneath it. He understands that the blade and chalice are represented by the two pyramids, and that the Holy Grail—the tomb of Mary Magdalene—lies hidden beneath the small pyramid, directly under the inverted one, 'beneath the starry skies.' He kneels in reverence.
