Marvel at the ornate frescoes, gilded carvings, and large globes that decorate this space. Then, follow your guide to the Astronomical Tower. On your way there, make a stop at the Meridian Hall. View the collection of instruments housed here and learn about how this space was used to determine the exact time of noon thanks to a small beam of sunlight shining through a hole in the wall.
