Observe the Palace
As you approach the edge, a formerly hidden circular fountain rises from below you, the pool of Latona, which we'll visit later. The alignment of the perspective, the color of the path you're walking on blending with the path beyond, the greenery near and far, gave no indication of the hidden details we've just uncovered. Le Nôtre has many such surprises in store for us. One which you can't see is the immense reservoir beneath your feet. We'll speak at the end about the incredible engineering marvels created to bring massive amounts of water here.
But now, please turn around to face the Palace.
[3 SECOND PAUSE]
The middle floor is the Hall of Mirrors, with 17 windows (the three you see on each side are separate foyers). For numerologists, 16 represents the four corners of the Earth, grounded as a 4x4 square. The number 18 represents the heavens, a 3x6 rectangle reaching to the skies. The number 17 then, in-between the two, is the Way, the means by which you ascend to Paradise.
The middle window on the middle floor aims dead center all along the Grand Perspective to an infinity point on the horizon. Behind that window, behind a hidden door to the Hall of Mirrors, are the King's chambers.
Turn left now and walk forward, keeping the Palace on your right.
