The Other Pyramid
In the ancient Mayan city of Chichen Itza is the Temple of Kukulcan, a Mesoamerican step-pyramid that overlooks the center of the city. Most famous for its staircases, which form triangular shadows during the spring and autumn equinoxes and create an illusion of a large serpent crawling down the pyramid, Kukulcan is aligned with the astronomical solar zeniths and was also used for sacrifices.
