The focal point of Chichen Itza is the 75-foot-tall Temple of Kukulkan, also known as El Castillo, or the castle. The Mayas, which invented the concept of zero, also mastered astrology. They created the temple as a physical calendar aligned with the sun. It's designed with such perfection that in the late afternoon on the spring and autumn equinoxes, the sun casts shadows depicting the plumes of a serpent that slithers down the steps. The creature's body eventually links with the stone serpent's head at the bottom of one of the staircases.
