Chichen Itza, an ancient Maya city in Mexico, was a vital political and economic center, with around 3500 inhabitants, built around 600 A.D. and later expanded by the Toltec civilization, blending two cultures. 1
El Castillo, or the Pyramid of Kukulkan, is Chichen Itza’s iconic structure. During equinoxes, sunlight creates a serpent-like shadow along its steps, symbolizing the descent of Kukulkan. 2
Chichen Itza was a hub of astronomical knowledge. The Maya aligned buildings with celestial events, including the observatory El Caracol, used to track Venus and seasonal changes. 3
