The iconic architecture of Chichen Itza was named one of the 7 wonders of the Middle Ages because of this pyramid. In addition to the well-preserved and magnificent appearance of the pyramid, the study of acoustics and astronomy by the ancient Mayan civilization was incredible. The echoes of the pyramids are like a bird in Mexico, and on the spring equinox and autumn equinox, the sun's light and shadow form a snake on the steps of the pyramid, which is the rain snake god worshipped by the Mayan civilization.
