Chichen Itza - "At the mouth of the well of the Itza."

Chichen Itza is the largest pre-Columbian archaeological city built by the Maya civilization located in the northern center of the Yucatan Peninsula, Yucatan, Mexico. It is one of Mexico's most visited tourist destinations.

Chichen Itza was a center of pilgrimage for the ancient Maya for over 1,000 years. The Maya name "Chichen Itza" means "At the mouth of the well of the Itza."

Dominating the center of Chichen Itza is the Temple of Kukulkan (the Maya name for Quetzalcoatl), often referred to as "El Castillo" (the castle).

"Templo de los Guerreros" (the Temple of the Warriors) complex consists of a large stepped pyramid fronted and flanked by rows of carved columns depicting warriors.

"El Caracol" (the snail), this structure was an observatory with its doors aligned to view the vernal equinox, the Moon's greatest northern and southern declinations, and other astronomical events sacred to Kukulcan, the feathered-serpent god of the wind and learning.
