All 4 Seasonal Fountains
You have now begun crossing the square. At the midpoint you'll be able to halt and see all four season fountains from the same spot. To get there, pay attention to the opening of the wood at 10 o'clock. As soon as you can see all the way through it, halt and pivot. Latona should be at your back, the middle of the green carpet should be in front of you, with your feet pointed toward the Grand Canal at high noon.
From this magic spot, without moving your feet, turn your head from your left shoulder clockwise to your right shoulder. Over your left shoulder is Bacchus or Fall, where you just came from, and over your right shoulder is Ceres, or Summer, which we saw before. But the real magic happens when you look DIAGONALLY through the woods at 10 o'clock on your upper-left, and at 2 o'clock on your upper-right to see far in the distance, the two seasonal fountains we haven't yet visited. It's a great spot for a unique panoramic photo.
Continue toward the biggest statue at 11 o'clock, walking right diagonally.
