Pyramid of Kukulcan at Chich'en Itza

Every equinox this Maya pyramid puts on a spooky ancient light show.

Twice a year, when the day and night are in perfect balance, this pyramid dedicated to the feathered serpent god Kukulcan (or Quetzalcoatl), is visited by its namesake deity. 

A two-and-a-half hour bus ride from Cancun takes you away from the thumping parties of spring break and into the once-thriving ancient capital of the Yucatán Maya, Chich’en Itza. During the spring and autumn equinoxes, thousands of tourists and locals pack in around the pyramid to recreate the parties of a thousand years ago—sans the cutting out of hearts—and to watch the “descent of Kukulcan.” A carnival atmosphere fills the surrounding meadow with the sounds of drums, traditional music, and cheering crowds.

In the Yucatec Maya tradition, Kukulcan (pronounced Koo-kool-kan) is a creator god who brings rain and winds. He is depicted as a feathered serpent, and closely related to the god Quetzalcoatl in Aztec mythology, and the god Gucumatz to Guatemala’s Quiché Maya. 

On the equinox, Kukulcan returns to earth to commune with his worshipers, providing a blessing for a full harvest and good health before entering the sacred water, bathing in it, and continuing through it on his way to the underworld.

A handclap near the base of the pyramid results in an unusual chirping echo, which is said to replicate the call of the sacred quetzal bird.

Legends aside, crafty and mathematically brilliant architecture combined with the natural rotation of the Earth creates an amazing and somewhat eerie image of a giant snake crawling down the temple. For five hours an illusion of light and shadow creates seven triangles on the side of the staircase starting at the top and inching its way down until it connects the top platform with the giant stone head of the feathered serpent at the bottom. For 45 minutes this impressive shadow stays in its entirety before slowing descending the pyramid and disappearing along with the crowd that gathered to see it.

The Pyramid of Kukulcan or Kukulkan (also known as El Castillo, a name given by the Spanish Conquistadors) is the center of Chich’en Itza, it was built over a preexisting temple between 800 and 900. It is the biggest pyramid in Chich’en Itza; at its base 53.3 meters wide on all four sides. It towers above the other monuments at 24 meters tall with a six-meter temple on top of the highest platform. Before access to the throne room of the pyramid was restricted, you could climb to the top and, on a clear day, see the top of the grand pyramid at the nearby ruin site of Ek Balam.

In 2015, researchers discovered a large cenote, or sinkhole cave, beneath the Pyramid of Kukulcan. It measures 35 meters across and is filled with water that reaches a depth of over 20 meters.

The Mesoamerican fascination with, and knowledge of, math and astronomy shines when examining the details of its architecture. Each of the four sides has 91 steps ascending it, 364 steps total, with the temple topping the pyramid considered an additional step, for a total of 365. Each step represents a day in the calendar. 

Additionally, the pyramid’s nine stages, bisected by a staircase on each side, represent the eighteen months of the Maya Calendar year. The pyramid was built to be a physical representation of the Maya Calendar (the same calendar that predicted the end of the world in 2012), while its orientation, slightly North East, is believed to have been calculated to create the phenomenon known as the “Descent of Kukulcan.”

This phenomenon is recreated nightly (artificially) during the Light and Sounds Show at 7 p.m. in winter and 8 p.m. in summer.

Chich’en Itza is spread over an area of four square miles (10 square kilometers). At its peak, it would have been home to an estimated 35,000 people. The site is one of the New Seven Wonders of the World and a UNESCO World Heritage Site

The archaeological site features various structures that are grouped into major clusters. The most famous and visited cluster is the Great North Platform where, besides the Kukulcan Pyramid, one can find the Temple of the Jaguars and the Great Ball Court.

Know Before You Go

From Cancun it is very easy to get a tourist bus to Chichen Itza. Or drive west on Hwy 180. Ask your hotel for more specific directions due to constant change in Mexican roads and lack of detailed information available online.
