Chichen Itza was the most important city of the ancient Mayans. It is located in the Yucatan Peninsula, on the north-eastern part of Mexico, about 80 miles west of Cancun. The colonnade in the stereograph belonged to one of the main buildings, on a site covering about one square mile. Chichen Itza, meaning the Mouth of the Wells of Itza, was founded in the 6th century AD and eventually became the most important city of the Mayan culture in the Yucatan. In the 13th century it was conquered by the Toltecs and finally abandoned about a hundred years before the Spanish arrived to the New World.

One of the most prominent structures remaining is El Castillo, a large pyramid rising to about 120 feet and housing the temple of Kukulcan at the top. It has stairs which can be ascended from 4 sides of the pyramid, a rather scary experience, especially when looking down, as there is barely anything to hang on to.
